Take a hybrid approach to data protection

The old fundamentals of data protection that required separate processes, systems and data for backup, DR and archive can’t keep up with today’s data capacities.

F

OR YEARS,

I’ve been among those promoting a best-practices approach to data storage protection that made clear distinctions among the processes and data related to backup, archive and disaster recovery (DR). Our articles here in Storage magazine more often than not followed the same track, addressing each of these activities separately much more frequently than as connected processes.

I still believe those distinctions are important to maintain. You copy data on a daily (or more frequent) basis to ensure that if a file gets deleted or corrupted you can easily retrieve a copy that’s a duplicate or at least a relatively recent version. That’s backup . Then there’s data you replicate so that if your company’s primary systems become unavailable because of a storm, fire or any other system-crippling occurrence, you’ll be able to start up at least some of your key applications so business can continue as near to normally as possible. That’s DR or business continuity . Finally, you probably also make copies of data that your company doesn’t need right now, but is bound by law or internal policy to hold onto—just in case it’s ever needed—and that’s archiving .

At its most basic level, each of those data protecting functions requires making a copy of data and putting it somewhere besides the primary storage on which it was created and where it’s still accessed. So, you could argue that treating backup, DR and archive as separate operations will result in redundant copies that need to be tracked, maintained and kept up to date. That’s true, and probably the biggest reason why so few companies hew to the practice

EDITORIAL  |  RICH  CASTAGNA of isolating each data storage protection activity . And those companies that wanted to were often thwarted by staggering data growth and the complexity of dealing with three distinct processes with short staffs and limited budgets.

Still other companies took a “leave well enough alone” approach and continued with a fairly dysfunctional data protection process that treated backup and

DR as equivalents, and considered their dusty old backup tapes an “archive.”

Both of these approaches are likely to fail at some point, possibly with disastrous results. So what’s needed is something that reduces the number of copies of data floating around, is a lot easier to maintain and can integrate easily into the overall storage management process .

So while a new methodology and maybe even some new tools to put it in motion are required, we need to remember that a few basic rules will still apply. There are still very different reasons for copying data for backup,

DR and archive, and there are very different reasons and methods of retrieving that data.

It’s possible that a single copy of data may suffice for both backup and DR, assuming the specific recovery tools are still available.

So any kind of hybrid data storage protection system has to meet the specific needs of each recovery scenario. Archiving should be considered more of a data preservation process that removes unused data from primary systems, effectively paring the amount of data that gets copied for backup and DR purposes.

It’s possible that a single copy of data may suffice for both backup and DR, assuming the specific recovery tools are still available. You’ll still need to be able to restore single files for routine recoveries from daily backups and have the ability to fire up new virtual servers to access production data from a remote site so that critical apps can continue to run even if the data center is out of commission. The data must also be copied to a remote site frequently enough so that it can be rolled back to a known, stable state if primary data becomes corrupted.

The good news is that a growing number of software and hardware vendors are developing products that meet these new requirements—no sacrifice when it comes to functionality, but with a simpler and less redundant process for copying data.

Startup Actifio touts its “virtual copies” approach, which reduces the number of copies of the same data that must be maintained for various purposes.

The company claims its Actifio Protection and Availability Storage (PAS) product can make managing copies much easier while saving on disk capacity. But more established vendors are also addressing the data protection sprawl issue.

CommVault has built a variety of protection apps on a common platform that makes each process easier to manage; avoids duplication; and even allows searching across data stored for backup, DR or archive. Symantec and other backup vendors offer similar functionality, and hybrid data protection is clearly the direction the industry is headed.

It all makes sense, and represents a break from traditional methods that have become less realistic and more expensive as the amount of data we store continues to grow. But it also makes sense to approach hybrid data storage protection with some caution; make sure that as you cut down the number of copies of data you retain, you still have sufficient and available tools to meet your

RTOs and RPOs. n

The dangers of 3D data

Get a 3D printer and build your own storage array. Or get a

3D printer and watch your storage array fill up with data.

A

WHILE BACK,

I read an article in a tech publication that discussed the concerns of toy companies regarding knock-offs of their popular toys being made by do-it-yourselfers using

3D printing. The article detailed how an increasingly inexpensive 3D printer—capable of converting a computer-aided design (CAD) model of an object into a physical (three-dimensional) version of the object by depositing layer upon layer of hardening plastic material—was being used to “print” things like Lego building blocks and Hasbro Transformers characters. I kept the article in my file folder of topics to track just in case

I ever needed another Optimus Prime figure.

I was reminded of this clipping when my dear wife told me recently that she wanted one (a 3D printer, not a Transformers figure) as a holiday or birthday present. It shouldn’t have surprised me that she was already expert on the processes for “dimension layer resolution and material deposition.” And since she was already pretty conversant with a number of 3D imaging and drawing programs that we use in our animated video work, she knew all the software and hardware elements required to make a working system.

She argued for the 3D printer with all the enthusiasm of a kid asking permission to keep a stray dog: “Assemble-it-yourself printers run about $500, while a good hobby-grade printer is about $1,000, and it will make its own replacement parts if anything breaks down.” This was strangely similar to the arguments I once made to get my parents to approve spending money on an early hobbyist computer kit.

“The files for 3D are comparatively small,” she continued, “ranging from a few hundred kilobytes to a gigabyte or 10 for very complex CAD models. So, our current video-editing storage array is more than adequately sized to hold the data.”

I was delighted to hear her trying to justify the purchase in terms of its impact on our data storage infrastructure, and so charmed by her approach that I stopped myself from observing that storage requirements might be a bigger issue if she develops her skills to a point where she wants to print a T-1000 (a mimetic poly-alloy assassin robot from Terminator 2: Judgment Day) or a life-sized electric car.

Another potential rub: copyright infringement. We all know the bad things that happen when your ISP gives your

IP address (and home address information) to the Recording Industry of

America, Motion Picture Association of America or to an attorney who has built a cottage industry around extorting money from copyright violators.

3D printing files may comprise yet another kind of data that needs to be spotted and segregated for review by risk managers to reduce exposure to potential legal prosecution.

The bootleg copy of Mars Attacks! or the bit torrent of “Slim Whitman Greatest Hits” you forgot you stored on a hard disk all those years ago are all it takes to see thousands of dollars drained from your kids’ college funds and deposited into the coffers of an aggrieved media conglomerate.

What if the object involved in your 3D printing project is itself copy protected? While you may be safe for now (in 2010, the European Court of Justice said Lego couldn’t trademark its product shape), lobbyists for manufacturers of everything from toys to torque wrenches are seeking to expand laws like the Digital Millennium Copyright Act ( DMCA ) to cover the shapes and designs of their wares. To give the effort teeth, they seek to extend liability for infringement to those who enable it as well as those who actually do the deed of printing.

What has this to do with storage? Is someone “printing” disk drives using

Seagate designs? Not that I know of. These 3D printing files may comprise yet another kind of data that needs to be spotted and segregated for review by risk managers in your business to reduce exposure to potential legal prosecution.

More directly, 3D printing may become a convenient way to generate memory chips comprising wafers of conductive and non-conductive polymers (plastics), an idea advanced by the three researchers who won the 2000 Nobel Prize in Chemistry . Who knows, you may need an alternative to gallium arsenide chips in the not too distant future to protect against infestations of GFAJ-1, a new life form discovered by NASA at California’s Mono Lake that appears to digest arsenic to sustain its vital functions.

Zerto Virtual Replication 2.0

Zerto Virtual Replication (ZVR) 2.0

is a hypervisor-based replication product that enables replication from a VMware vSphere environment to a VMware vCloud environment, and vice versa.

Version 2.0

is hardware-agnostic, and offers multisite replication, off-site cloning and backup with support for virtual machine (VM) boot order and automatic updates of VMware vApp changes. Full integration with VMware vCloud Director is offered, as well as full awareness of VMware vMotion, Distributed Resource Scheduler and High

Availability.

Because the product is hardware-agnostic, users can set up different tiers of storage, repurpose older storage and mix storage vendors. Multisite replication allows users to protect their main data center and remote offices; data can be replicated from any site to any site or from many sites to one shared infrastructure.

Virtual Replication 2.0’s off-site cloning and backup lets users create copies of VMs for testing, backup or development without any impact on the production environment; the product’s journal can now store up to five days of data to protect against corruption. Another new feature, infrastructure masking, allows administrators to limit access to parts of the infrastructure for security.

Full integration with vCloud Director enables replication from vSphere to vCloud and offers multi-tenancy for cloud environments , which ensures separation of department or customer data within a shared infrastructure. In the past, multiple instances of vCenter were necessary for multi-tenancy, which increased cost and complexity.

Zerto Virtual Replication also allows for centralized management, so users don’t have to switch back and forth between vCloud Director and vSphere consoles.

One of our judges said the product took an “interesting and fresh approach for an important new environment.” Another said Zerto Virtual Replication 2.0 was a “highly innovative, simple alternative to [storage resource management] SRM” and called the

VMDK-awareness “ingenious.”

Actifio Protection and Availability Storage 5.0

Multiple data protection applications create multiple copies of the same data, which contributes to data growth. Actifio Protection and Availability Storage (PAS) 5.0

replaces multiple data protection and availability storage applications with a single, complete storage system to manage numerous copies of data generated from backup, snapshots, replication, analytics, test and development environments. The Actifio PAS platform uses virtualization to eliminate multiple copies of data created by separate data protection applications. It’s also intended to replace tools like WAN optimizers and deduplication appliances.

The PAS Virtual Data Pipeline technology creates virtual pointin-time copies of production data, eliminating backup windows while making data instantly available to applications. Only one copy is saved and updated with incremental changes. Actifio PAS can be deployed in a single-site configuration or among multiple sites to use its native replication capabilities.

PAS users can consolidate devices and software licenses, using one license to protect a data volume, regardless of the number of user sites or data centers. Since its data store is virtualized, PAS lets you use any third-party SAN as a back-end device. The Actifio

Enterprise Manager can manage multipetabyte PAS environments via a single console.

Actifio’s DeDupe Async technology also reduces network bandwidth utilization, so separate WAN optimization hardware and software isn’t needed. For cloud environments, the system provides multi-tenancy, network optimization and advanced reporting capabilities.

Actifio PAS connects to any host through a Fibre Channel or iSCSI link. Actifio’s

20T system scales to 20 TB, and is intended for remote or branch offices and small-tomidsize VMware and Oracle environments. The 100T system scales to 100 TB for data centers or compute farms, big data applications, and heterogeneous physical and virtual environments. The PAS enterprise edition, which can grow to more than 100 TB, is for cloud or managed service providers, and globally distributed enterprises.

ExaGrid Systems Inc. EX130-GRID with Secure Erase

The EX130-GRID encrypted disk backup with deduplication system and Secure Erase is a deduplicating backup target device that can encrypt backup data with its Secure

Erase feature that eliminates the risk in backup data security breaches . In most filebased systems, deletion means marking areas of a disk as free but actually leaving the deleted data intact until it’s later overwritten. For companies with high security concerns, that approach is inadequate as they need assurances that deleted information has been destroyed and is unrecoverable. Secure Erase uses a deletion technique that truly removes data by performing overwrites to the affected areas, ensuring that the previous data is not recoverable.

The system can erase data from an entire node or down to more granular levels such as a single backup job.

To ensure that data at rest is always encrypted, the 130 TB disk backup system uses Seagate’s Self-Encrypting Drive

(SED) with 128-bit AES. The system can ingest and return data at up to 24 TB per hour and supports advanced virtual machine recovery . It’s compliant with the Department of Defense 5220.22-M standard and the National Institute of Standards and Technology SP800-88 standard.

QLogic Corp. FlexSuite 2600 Series Fibre

Channel Adapters

QLogic Corp.’s FlexSuite 2600 Series Fibre Channel adapter won the networking equipment category in the Storage magazine/SearchStorage.com 2012 Products of the Year competition. Only one product was presented with an award in this category this year.

As organizations upgrade their SANs to 16 Gbps Fibre Channel (FC) and 10 Gigabit

Ethernet (GbE), networking products that are upgradeable to the newest technologies but preserve investments in existing infrastructure will be essential.

The sixth-generation QLogic 2600 Series FC adapter supports 16 Gbps FC throughput per port with full hardware offload, and is backwards compatible to 8

Gbps and 4 Gbps networks. More impressively, the 2600 Series is transformable to a converged network adapter

(CNA) to support 10 GbE networks.

With a single PCI Express (PCIe) slot, you can install a host bus adapter for your 8 Gbps or 4 Gbps

FC network, and use the same PCIe

3.0 card when you upgrade to 16

Gbps FC or 10 GbE.

“CNA cards are approaching a strategic default, and the flexibility of this card fits an unpredictable IT future,” commented one judge.

The FlexSuite 2600 Series also received high marks for performance and functionality.

A field-programmable firmware upgrade is all that’s required to transform the FC adapter into a QLogic 8300 series 10 GbE CNA. It will then support network interface cards, Fibre Channel over Ethernet (FCoE) and iSCSI traffic.

And just because it’s so flexible doesn’t mean it won’t perform as well as fixed 16

Gbps FC adapters. The 2600 Series can provide up to 1.2 million IOPS as a full-duplex, line-rate 16 Gbps FC adapter. As a 10 GbE CNA, it supports up to 1 million FCoE IOPS.

QLogic provides the QConvergeConsole single-pane management application with the adapters. They also support application programming interfaces from most thirdparty management tools such as VMware Inc.’s vCenter for virtualized environments.

The dual-port FlexSuite 2672 is priced at $2,225 with a five-year warranty. A singleport model (the 2670) is also available. In dual-port configurations, each port has its own processor, memory and driver for high availability. This port-level isolation means that if one port fails, the second port continues to operate without interruption.

Dell Inc. vFoglight Storage 2.0

Dell’s vFoglight Storage 2.0 won the gold in the 2012 Products of the Year storage management tools category (this year, only one prize was awarded in this category).

Version 2.0 of vFoglight Storage is designed to give server and storage administrators a common performance monitoring tool . The product is Dell’s “last-mile” module for its Foglight performance management software family, which it acquired when it bought Quest Software in September 2012. At the application level of the product family is Dell’s Foglight, which monitors performance from an application level through physical hardware. Its vFoglight carries that monitoring through to the virtual hardware . vFoglight Storage extends monitoring to the storage that supports the servers, to pinpoint performance problems within the storage or to help identify problems in the adjacent infrastructure that may be affecting storage performance.

The agentless product, which is included with vFoglight, allows users to see how much I/O is generated by each virtual machine. Its functionality is accomplished by combining metrics data from VMware vCenter, the storage array and the switch.

Dell vFoglight Storage 2.0

, which shipped in early October 2012, allows users to “rewind” (like a DVR) to examine past events in storage devices, applications and servers, to determine the source of a performance problem. The new version also adds compatibility with the EMC VNX and Dell Compellent platforms, as well as data and user interface integration with Dell’s vOPS Server Enterprise.

Our judges gave vFoglight Storage 2.0 the highest marks in the storage management tools category in five of the six ratings areas: ease of use and manageability, innovation, performance, ease of integration and value. One judge said vFoglight Storage 2.0 provides “excellent all-around storage and network management.”

Pricing for vFoglight Storage 2.0 is $1,298 per CPU socket when purchased with vFoglight. This version of vFoglight Storage requires vFoglight Version 6.7.

drives (SSDs) for faster retrieval. All Tegile arrays have FlashVols that pin data into

SSDs, ensuring maximum quality of service to those volumes so they run at maximum performance.

Tegile’s reporting allows users to associate storage resources to virtual machines, accelerating capacity and performance planning as well as troubleshooting. Tegile also uses in-line compression and data deduplication for its SSDs and hard drives, which it claims can increase usable capacity up to five times. The arrays feature snapshots and remote replication for data protection.

Zebi arrays support Fibre Channel, iSCSI and network-attached storage (NAS) protocols. An array can be optimized for backup operations with high network throughput and in-line dedupe and compression, or for virtualization with high IOPS. For caching,

Zebi arrays use a combination of DRAM and SSDs.

Our judges gave the HA2800 high marks for innovation and value, with its base price of approximately $235,000. One judge called the system “One of the more complete hybrid unified storage products—full storage array functionality and excellent performance at a reasonable price.”

Another judge noted that the HA2800’s “inline dedupe and hybrid disk, and snapshot and replication make for a comprehensive feature set.”

NexGen Storage Inc. n5-150 Storage System

Startup NexGen designed the n5 Storage System to deliver storage quality of service

(QoS). That means IT administrators can guarantee performance to specific applications and isolate workloads from one another on the SAN. Its users can provision performance in the same way they would provision capacity, so they can apply different

QoS profiles to multiple applications simultaneously.

NexGen’s hybrid iSCSI systems use

Fusion-io PCI Express

(PCIe) flash cards along with hard drives, and they tier data in realtime with their Dynamic

Data Placement feature.

The n5-150 is the largest of NexGen’s three models. It scales from 2.4 TB to 4.8 TB of

SSD capacity, and from 48 TB to 192 TB of overall storage capacity.

Judges gave NexGen high scores for innovation, with one calling out its QoS and use of PCIe solid-state drives (SSDs) in a hybrid architecture.

NexGen offers a performance guarantee for the n5-150, promising to double the system’s capacity or improve performance by 50% for free if it doesn’t increase performance of a user’s previous disk system by 10 times, triple IOPS per rack unit of hybrid storage or triple the capacity per rack unit of all-SSD arrays.

Nimbus Data Systems Inc. Gemini Flash

Memory Array

Nimbus is already three generations into its all-flash array architecture, and the Gemini model comes with a 10-year warranty for multi-level cell (MLC) flash . That’s about twice as long as the expected maximum life of most flash systems available today.

Gemini also has a new processor and Parallel Memory Architecture that stripes I/O across a non-blocking internal switch to increase throughput and eliminate the need for over-subscription. Each flash drive has dedicated bandwidth to the controller and runs at line-rate speeds. The flash array can scale to 48 TB in a 2U device.

Nimbus claims it can sustain

1,000,000 IOPS.

Nimbus Data Systems’

Gemini can support 1 GbE/10

GbE/40 GbE iSCSI, 8 Gbps and

16 Gbps Fibre Channel, and 40

Gbps and 56 Gbps InfiniBand connections.

Our judges found that Gemini goes beyond just the performance you’d expect from a flash array. It also supports block and file storage and has dual controllers for high availability.

“Excellent unified storage functionality in an all-flash array ,” one judge wrote. “It has broad interconnect support and high performance in a no-single-point-of-failure architecture.”

Microsoft Corp. Windows Server 2012

The many new data storage features and enhancements in Microsoft’s Windows Server

2012 caught the attention of our judges in the storage system software category of this year’s Storage magazine/SearchStorage.com 2012 Products of the Year competition.

The latest version of Microsoft’s server operating system earned the highest average score for functionality among the 11 storage system software finalists. Windows Server

2012 also was tops in value, ease of use and manageability, and ease of integration into existing environments. One judge cited the “great new innovations” in the product.

Among the most prominent new features are Server

Message Block (SMB) 3.0

for high-throughput, low-latency data transfers between servers and storage; the Resilient

File System ( ReFS ), which offers greater scalability than

NTFS; Storage Spaces virtualization technology to create storage pools and enable failover between multiple nodes on commodity hardware; data deduplication; clustering enhancements; and virtualization improvements, such as live storage migration and Hyper-V Replica disaster recovery .

“This version of Windows will be very appealing to Microsoft shops,” said one judge.

“It’s faster, has better storage performance, is more flexible and it’s more feature rich.”

The IT manager of a Midwestern grain processing company said Storage Spaces is an important feature that will help to lower the entry cost for shared storage, facilitating a “just a bunch of disks” (JBOD) configuration.

“This is going to be huge in the SMB space,” predicted the IT manager.

A senior system engineer at a large, diversified manufacturing and retail company in Eastern Europe said he’s happy to have the ability to use a continuously available file server for Hyper-V workloads. “It simplifies storage management and decreases investments into an expensive Fibre Channel infrastructure,” he wrote in an email.

Microsoft announced the general availability of Windows Server 2012 in September

2012. Windows Server 2012 also serves as the underlying technology for Windows Storage Server 2012, which is used in NAS and iSCSI storage systems sold by OEMs.

Atlantis Computing Inc. ILIO Diskless VDI 3.0

Atlantis’ ILIO Diskless Virtual Desktop Infrastructure (VDI) 3.0 scored the highest average marks for performance of all the entries in the storage system software category. The software reduces the size of virtual desktop images , making it possible to store them in the local server’s memory, rather than disk drives, and to reduce their boot time.

One judge on our panel called Atlantis ILIO Diskless

VDI software “highly innovative software that reduces VDI infrastructure requirements and admin manual-labor-intensive tasks.” The judge viewed the product as the “true definition of doing more with less: higher performance at lower cost.”

Atlantis ILIO Diskless VDI is installed on each physical server that runs virtual desktops. The software requires a Citrix XenServer, Microsoft Hyper-V or VMware vSphere hypervisor. When deployed, Atlantis ILIO Diskless VDI becomes the NFS or iSCSI data store for Citrix XenDesktop or VMware View virtual desktops.

Product features include inline deduplication, in-memory compression, automation of installation and configuration, and content-aware analysis of I/O operations in realtime at the NTFS file-system and block levels.

VeloBit Inc. HyperCache 1.12

One of the hottest trends in storage is server-based flash caching, and VeloBit Hyper-

Cache 1.12 stood out in an increasingly crowded field, scoring high marks from the judges on performance, value and ease of integration into the data center environment.

Like other flash cache software, HyperCache is able to boost performance without changes to existing applications, storage or data protection. The product works with any type of solid-state drives, including PCI Express and

SATA, and supports major operating systems and hypervisors.

One of the main differentiators VeloBit touts is Hyper-

Cache’s content-locality caching algorithm, which prioritizes data in the cache based on popularity rather than how recently it was used. Another point of distinction from some other flash cache software is Hyper-

Cache’s support for both read and write caching.

“Good idea, good price,” commented one judge.

Other product features include data compression, user-defined write-cache depth, automatic performance optimization, and a performance monitoring utility that displays metrics in real-time and enables past-performance analysis.

The benefits of virtualizing servers and desktops are usually evident, but the storage side of the shop often struggles to support virtualized environments. Here’s what storage vendors are doing to address the problem.

THE NOTIONS OF CONSOLIDATION

and aggregation, and the anticipated efficiency gains and lower costs that will be realized from those approaches, have been the primary drivers behind the adoption of server virtualization and virtual desktop infrastructure (VDI). While virtualization has generally lived up to its promises, with less physical infrastructure needed to support servers, desktops and applications, it has had a less advantageous effect on storage. “With server virtualization and VDI, storage has become one of the main virtualization challenges,” said Mark Peters, a senior analyst at Milford, Mass.-based Enterprise

Strategy Group (ESG).

VM-SPECIFIC  STORAGE

The complexity of shared storage, inconsistent performance related to resource contention caused by virtual machines ( VMs ) competing for available storage resources, and storage management challenges have been the main areas of concern. As these challenges abound, there’s an increasing list of vendors offering products that employ techniques and strategies to solve or at least mitigate the storage challenges that have plagued virtual server and VDI deployments up to now.

CONVERGING VM

s

AND STORAGE

Collapsing server virtualization and storage, with both compute and storage services running on a single system, is touted by one group of vendors as the ideal approach. The idea is to dedicate a certain percentage of the computing resources of the underlying host to storage tasks and the remaining resources to virtual machines. The simplification resulting from including and managing storage within a single platform is the primary value proposition. Being able to optimize and manage storage better in relation to VMs can be another benefit of combining storage and VMs in a single system. On the downside, and depending on the underlying design, combining storage and VMs in a single system can limit the ability to scale storage and computing resources independently of each other. Moreover, in solutions where storage and VMs share the same underlying computing resources (CPU, memory and networking), storage processing is more likely to impact VMs and vice versa.

A handful of vendors are now offering converged virtualization and storage products.

On the lower end of the spectrum, Scale Computing with its HC3 system offers converged virtualization and storage systems for small and medium-size companies. Descending from a multinode scale-out NAS origin, HC3 runs the open-source Red Hat KVM hypervisor on top of its storage system. With all storage and virtualization tasks managed within a single console and an all-inclusive licensing model that covers the cost of the hypervisor, HC3 tries to minimize the cost and complexity of server virtualization for smaller environments.

While Scale Computing added virtualization to its storage platform, Nutanix

Inc. took a server-centric approach where the storage stack simply runs as an additional service parallel to the VMs. Nutanix virtualizes storage from physical server nodes into a unified pool of scale-out converged storage (SOCS),

VM-SPECIFIC  STORAGE with VMs running on each server accessing the shared storage pool as if they were accessing a SAN. With a software-based scale-out NAS architecture and hybrid solid-state drive (SSD)/SATA storage nodes claiming NetApp-parity in storage features, Nutanix targets both SMBs and enterprises.

Contrary to Nutanix, SimpliVity Corp., with its OmniCube platform , claims to be a storage platform first that can also host virtual machines. A VM-centric scale-out NAS targeted as primary storage, with features like real-time data deduplication and compression, cloud integration and hybrid SSD/SATA storage nodes, it competes head-on with Nutanix.

Pivot3’s vStac unified storage and compute product shares the block storage of local servers into an iSCSI SAN, which can be accessed by VMs running on those servers. Pivot3 is targeting its converged storage and compute platform at the VDI and surveillance markets.

MANAGING STORAGE AT A VM LEVEL

Traditional storage is usually managed and provisioned to servers at a LUN or volume level and shared among multiple VMs. As a result, it’s been difficult to perform storage management tasks, such as snapshotting or replication, at a VM level. Several storage startups have acknowledged this problem and bypassed traditional LUN/volume-based storage management for a VM-centric model.

Tintri Inc., with its VMstore product, offers a hybrid disk/SSD dual-controller storage system for virtualized server environments that features real-time deduplication; Tintri claims to keep all active VM data in SSD while it shuffles inactive data to SATA disks in the background. Most significantly, Tintri provisions and manages storage at a VM level . Cloning, snapshotting and replication are all performed at a VM or virtual-disk level. “We are able to monitor and control I/Os by VM and, as a result, are able to have both server and desktop VMs on the same server,” said Kieran Harty, Tintri’s CEO. Similar to Tintri, both Nutanix and SimpliVity provision and manage storage at a VM level.

The price they pay for managing storage at a VM level is that these storage systems can no longer be used to serve non-virtualized physical servers. In fact,

Nutanix, SimpliVity and Tintri are currently only available for VMware, but all three vendors claim to be hypervisor-agnostic, and both Nutanix and Tintri

said they’ll support Microsoft Hyper-V and Red Hat KVM in the near future.

Traditional storage vendors have been busy adding the ability to get VMspecific metrics and monitoring to their reporting and monitoring tools. “EMC

Storage Analytics, available for VNX and VMware first [Q1/2013] is designed to do predictive analysis to be able to spot problems on a VM and LUN,” said Eric

Herzog, senior vice president (VP), product management and product marketing, EMC.

SOFTWARE-DEFINED STORAGE AND

VIRTUAL STORAGE APPLIANCES

By definition, virtualization decouples application services from the underlying hardware and there’s a clear trend for it to expand beyond computing. Examples of this shift include software-defined networking ( SDN ), which has gotten much buzz lately, and VMware Inc.’s active promotion of the concept of software-defined data centers ( SDDCs ). Software-defined storage ( SDS ) is simply a part of this concept, and a number of storage vendors are picking up on it.

For instance, Nutanix touts its solution as software-defined storage that runs on a standardized sheet metal infrastructure. Virtual storage appliances (VSA) , where the storage software runs on a virtual machine and is distributed as a VM image, are other examples of this trend of abstracting the storage application from the underlying hardware. The VMware vSphere Storage Appliance transforms the local storage of up to three servers into a shared storage resource that runs virtualized applications. Similarly, NetApp Inc.’s Data Ontap Edge is a virtual machine that runs Data Ontap, currently only supporting a single server node, but able to seamlessly interact with other NetApp storage. Hewlett-Packard (HP) Co.’s StoreVirtual VSA , based on the LeftHand OS, is able to pool the local storage of up to 10 hosts and present it as shared storage.

VM-SPECIFIC  STORAGE

But at the same time, it has increased the performance requirements of storage systems,” said Greg Schulz, founder and senior analyst at StorageIO in Stillwater, Minn.

Storage systems in virtualized environments have to be able to withstand spikes such as “boot storms,” in which a large number of systems tax the storage system simultaneously. Solid-state storage plays a major role in dealing with this problem. While disks perform reasonably well with sequential workloads, they fare poorly with random workloads of virtualized servers and desktops.

Available flash-based storage products can be categorized into two groups:

● ●

All-flash arrays

● ●

Hybrid flash/disk arrays

All-flash array vendors target the very high end of the application market, where latency needs to be minimized at any cost and the number of IOPS maximized to as high as 1 million-plus. Nimbus Data, Pure Storage, Violin Memory and Whiptail are key players in the all-flash storage array market . As a result of the high cost of SSD, all-flash arrays are pricey and data reduction techniques like compression and data deduplication are often not an option since they may adversely impact performance. With the focus on performance, some all-flash array vendors are lacking a few storage features of traditional storage arrays.

Hybrid flash/disk arrays combine SSD and high-capacity disk drives to achieve a favorable price-performance ratio. While their performance doesn’t usually exceed a few tens of thousands of IOPS, they cost much less than allflash arrays. Instead of targeting the very high-end market, they target the mass market. Besides traditional storage vendors, several startups, such as Green-

Bytes, Nimble Storage and Tegile Systems, offer hybrid flash/disk products with a focus on the virtualized server and VDI market . Hybrid flash/disk storage arrays are more likely to enable inline deduplication or compression. “Unlike NetApp, our metadata acceleration engine deduplicates across the whole array,” said Rob Commins, Tegile Systems’ vice president of marketing.

HYPERVISOR INTEGRATION

The integration with hypervisors has been one of the main differentiators of storage products that target the virtualized server and desktop market. VMware

has spearheaded storage APIs (see “ Key hypervisor storage APIs

”) that allow offloading of storage tasks, such as snapshotting and copying, to the storage system, and that enable reporting on and managing storage from within hypervisor management tools such as VMware vCenter. Microsoft Windows Server

2012, with its greatly improved SMB 3.0 file system and Offloaded Data Transfer (ODX) feature that enables offloading of storage tasks to storage arrays, is clearly narrowing, if not closing, the gap with VMware. Evaluation of the level of integration of a storage system with hypervisors should be a top priority when evaluating a storage system for virtual servers or VDI.

ASSESSMENT AND OUTLOOK

With multiple competing approaches and products, choosing the right product for your virtual server and VDI infrastructure may seem intimidating. The simplicity of a converged VM/storage product is appealing as long as scalability concerns can be addressed and you can tolerate that they can only be used as storage for supported VMs. Proven packaged turnkey solutions may be more expensive but are most likely to scale and perform as expected. And, by relying on the experience and support of the vendor, they’re especially attractive in larger virtual server and VDI deployments with limited IT resources. While all-flash arrays have a place for very high-end applications where performance matters most, hybrid flash/disk arrays from both traditional storage vendors and startups are likely to dominate, especially if they take advantage of available storage APIs and integrate tightly with hypervisor products.

Server and desktop virtualization is significantly impacting the direction of storage products, and features such as VM-specific storage management and software-defined storage are likely to play a bigger role in evolving storage systems. n

Among the technologies being employed to help address application and data growth are server virtualization, solid-state storage technologies and a new generation of servers. Although very different, these technologies share a common characteristic: they demand I/O and flexible configurations that many storage fabrics simply can’t provide.

● ●

Server virtualization. Server virtualization is solidly entrenched in today’s

IT environment, and the number of virtual machines (VMs) deployed per physical host is growing. Not long ago, five to 10 VMs per host was typical,

STORAGE  NETWORKING often based on the number of processor cores and amount of memory available in the physical server. Recently, it has become more common for a single physical server to host 15, 20 or 25 VMs. As the density of virtual machine deployments increases, so does the I/O on the storage network.

● ●

Solid-state storage. Solid-state storage provides a tremendous boost in data storage performance and, for the first time, our lab tests are beginning to show that storage devices are no longer the data center bottleneck in many cases. That’s the good news; the bad news is that the bottleneck is shifting to the storage network.

● ●

PCI Express (PCIe) 3.0. The latest generation of data center servers includes the PCIe 3.0 peripheral interface. PCIe 3.0 supports twice the bus speed of the previous PCIe generation, and these newer servers support up to double the total number of lanes of PCIe per processor, resulting in a quadrupling of the total I/O bandwidth available in a single server. These new servers produce network-taxing I/O, but have enough horsepower to offer

10 Gigabit Ethernet (10 GbE) on the motherboard, which is a step toward wider adoption and more affordable prices for 10 GbE.

NEXT-GENERATION STORAGE INTERFACES

The networking industry is responding to these new demands, offering enhancements to existing networking products and protocols, as well as more innovative responses to growing I/O issues. Not only do we have higher speeds available for all familiar storage interfaces, including Ethernet, Fibre Channel

(FC) and others, but we also have ways to virtualize the I/O path that are particularly complementary to server virtualization.

Ethernet. Ethernet is widely used for both data and storage networking.

Ethernet provides a good transport for file storage protocols such as Network

File System (NFS) and Server Message Block (SMB, formerly known as CIFS), and can also be used for block storage protocols such as iSCSI and Fibre Channel over Ethernet (FCoE).

The 10 GbE specification was ratified in 2002, yet a decade later use of 10

GbE is just beginning to pick up and it soon will become the dominant Ethernet

STORAGE  NETWORKING connection interface. According to the most recent Storage magazine/Search-

Storage.com Storage Purchasing survey, 28% of respondents have implemented

10 GbE for their storage networ ks (versus 30% with 1 GbE); two years ago, only 13% had deployed 10 GbE. Early uses of 10 GbE were limited to trunking between switches and the components were expensive. The 10GBASE-T specification, ratified in 2006, described the familiar RJ45-style Ethernet and with it the promise of a lower price- per-port for 10 GbE.

Increasing adoption of 10 GbE might also be attributed to blade servers, which typically have 10 GbE interfaces in the blade chassis, and the declining prices of 10 GbE components.

According to the most recent

Storage magazine

SearchStorage.com Storage

Purchasing survey, 28% of respondents have implemented 10 GbE for their storage networks.

There are two different connector types used with 10 GbE: SFP+ and

RJ45. The SFP+ connector technology has been around for several years and is the same technology that’s used with 8 Gbps and 16 Gbps Fibre Channel connections, although with different line rates. 10 GbE SFP+ is available with either copper or fiber-optic cables . The copper cables, known as Direct Attach

Copper (DAC), have the transceivers mounted directly on the cable, and are good for short distances such as within a rack or to a nearby rack. The fiber-optic cables generally require the transceiver to be mounted into the cage in the switch or adapter port. The fiber-optic cables are used for short and moderate distances.

The RJ45 connectors are the familiar connectors used on Cat5, Cat5e and

Cat6 Ethernet cables. 10GBASE-T cables should be Cat6a or Cat7 to use the full supported distance of 100 meters. Cat6 cables can be used with 10GBASE-

T environments up to 55 meters. Cat5e cables aren’t recommended for 10 GbE.

The 10 GbE server adapters support SFP+ or RJ45 connectors, but not both on the same adapter. 10 GbE switches support either SFP+ or RJ45, although some support both in the same switch.

Even as 10 GbE products are beginning to proliferate, 40 GbE and 100 GbE specifications were ratified in June 2010. These technologies are available in products today, but they’re expensive and primarily used for switch-to-switch trunking or aggregation. These technologies use multiple lanes of 10 GbE to

Fibre Channel is still the dominant high-end storage networking architecture , satisfying enterprise workloads, server virtualization and cloud architectures.

The technology is known for its reliability and high performance.

Ethernet.

We’ve seen the first 40 Gigabit Ethernet (GbE) host adapter cards become available, and more are expected in 2013. The next server refresh cycle, probably happening in the second half of 2013 or early 2014, will trigger yet another wave of new I/O capabilities, including more 40 GbE host adapters.

● ●

Fibre Channel.

The 32 Gbps Fibre Channel (FC) specification is expected to be stabilized in the first half of 2013. Once it’s stabilized, products are expected within a year or two. Figure on seeing 32 Gbps FC products in late 2014 or early 2015.

1997, when the first 1 Gbps FC components became available. The current top speed is 16 Gbps FC, first introduced in switches and adapters in 2011. As a

SAN interface, FC is very much alive and well, and work is already underway on development of 32 Gbps FC. These days, FC is rarely used on the back end— as a disk drive interface for enterprise disk drives—because drive manufacturers have moved to SAS for that interface.

FC maintains backward compatibility with at least two previous generations, so 16 Gbps FC works with 4 Gbps and 8 Gbps FC gear. Current 16 Gbps FC SAN switches are also backward compatible with 2 Gbps FC. That means a company can upgrade adapters, switches and storage systems independently, without having to upgrade the entire FC SAN infrastructure at one time.

Hardware isn’t the only issue. VMware vSphere 5.1 and Windows Server

2012 (and Hyper-V) support and have specific knowledge of 16 Gbps FC and,

Fibre Channel maintains backward compatibility with at least two previous generations, so 16 Gbps FC works with 4 Gbps and

8 Gbps Fibre Channel gear.

in some cases, have in-box drivers for some 16 Gbps FC components. With these hypervisors both supporting 64 virtual CPUs and 1 TB of RAM per virtual machine, it’s not hard to imagine a virtual server environment that can easily take advantage of the increased I/O bandwidth. Windows Server 2012 with

Hyper-V also supports Virtual Fibre Channel. For the FC host bus adapters

(HBAs) that support N_Port ID Virtualization (NPIV), this allows a guest VM to access a virtual FC HBA directly, giving the virtual machine the same Fibre

Channel support and access as a physical machine.

I/O VIRTUALIZATION

Virtualizing the I/O path allows physical devices such as network or storage adapters to be allocated as multiple logical devices; conversely, it also makes it possible to combine physical devices into larger logical devices. In the Fibre

Channel example above, we can see that virtual Fibre Channel allows us to take advantage of NPIV, providing multiple virtual FC HBAs to guests in a virtual machine environment.

Single-root I/O virtualization is another way to share I/O adapters such as

Ethernet network interface cards (NICs). Not only can these NICs be shared among several guests in a virtual machine environment, the management of this sharing can be offloaded into the card, freeing up host CPU cycles. This is now supported for Ethernet NICs in most hypervisors.

SOFTWARE-DEFINED NETWORKS

If you’re running a hypervisor, you already have one form of a software-defined network ( SDN ). The hypervisors can use the Ethernet NICs to make a virtual network switch within the adapter, providing network switching functions entirely within a server. For network activity that stays within the guests running on one physical server, this becomes a form of a software-defined network.

Other forms of SDN that have emerged recently separate the control functions from the hardware itself. These are especially appealing with cloud providers who have to pool resources across multi-tenant environments.

The Open Networking Foundation is leading an industry effort to move

SDN forward. However, SDN is still very new with much yet to be developed.

It looks like an interesting effort and promises to provide several benefits, including improved automation and management of networks, and the opportunity to increase the speed of innovation. n

We need a backup dedupe layer

As backup dedupe matures, it’s still very much a proprietary technology. We need standardization to eliminate some of today’s software-hardware headaches.

J

UST ABOUT EVERYONE

who works with disk-based backup understands the need for data deduplication. For many, that includes the use of a deduplication storage appliance as a data backup target . Most backup software products can use deduplication appliances that present themselves as either a file share (NFS or CIFS) or a tape device (virtual tape library or VTL). The challenge with those approaches is that the backup software doesn’t know it’s writing to a deduplication target. All the data is sent from the backup software to the appliance, and then most of the data is discarded when the appliance determines it has it stored.

If simply leveraging a deduplication appliance was “Dedupe 1.0,” then

“ Dedupe 2.0

” is to optimize the process by making the backup software deduplication-aware. It seems as if almost every deduplication array now offers API libraries that enable backup software to optimize the backup process, such as:

● ●

EMC Data Domain with DD Boost

● ●

● ●

HP StoreOnce Catalyst

Quantum DXi with Accent

The list goes on, but the point is that for backup software users to better leverage their deduplication hardware , their software provider has to embrace that particular hardware vendor’s accelerator APIs. Of course, many of those hardware providers also sell data backup software that leverages those APIs, such as EMC NetWorker with Data Domain or HP Data Protector with StoreOnce.

We can classify the alternatives a little differently, on a “good-better-best” scale:

● ●

● ●

“Good” deduplication is simply using a deduplication appliance.

“Better” deduplication involves a backup server that’s dedupe-aware.

● ●

“Best” deduplication enables deduplication at the production source server within the backup agents.

Unfortunately, there are very few hardware plus software “best” offerings.

For example, EMC Data Domain offers a “best” solution with NetWorker

(meaning its deduplication can occur client-side), whereas other software solutions that leverage Data Domain only offer “better” deduplication from the backup server . This isn’t a knock on EMC, but on the complexity of adding those deduplication APIs to the client agents. If a third-party software vendor wanted to deliver a “best” deduplication experience that still appealed to that software vendor’s broad customer base, they would have to engineer their agents to use DD Boost, Catalyst, Accent and others, and then absorb some appreciable development, testing and support requirements.

One backup software vendor, Symantec, has a different approach through its OpenStorage Technology (OST) mechanisms . Instead of the deduplication appliance presenting itself as a VTL or file share, or offering its own API accelerator, it can support Symantec’s OST standard that provides interoperability with Backup Exec and NetBackup. Essentially, instead of the software vendors writing to the APIs of one or more hardware vendors, the hardware vendors write to Symantec’s OST specifications. Hardware vendors do this because of the Symantec products’ time and presence in market, but what if other software vendors each published specifications similar to OST? This creates the same challenges described above, where each hardware vendor would have to develop and support multiple software specifications.

So, what’s the answer? In a perfect world, there would be a data deduplication API layer that works across wide ranges of backup software and hardware vendors. Symantec OST is used by many hardware vendors, but only with Symantec software products. EMC DD Boost has a broad ecosystem of software partners, but it only works with EMC Data Domain appliances. What would happen if Symantec or EMC licensed the API libraries for interoperability across all hardware/software players? Who would support it, and what would

HOT  SPOTS  |  JASON  BUFFINGTON happen to the differentiation in the “better together” stacks? At first glance, it appears to benefit a variety of constituents, including participating vendors, partners, and IT organizations struggling with the current mixing and matching. But in reality, it’s a chicken-and-egg challenge and nobody is moving.

A standard backup data deduplication layer may seem like a pipe dream, but it isn’t the first time it’s been suggested. At one time, backup software vendors each wrote their own backup software agents per application workload. Each of those software vendors did their own engineering to understand how to get the data out of the databases and other production applications, as well as how to restore the data. Meanwhile, storage hardware vendors used to create their own application agents to enable their own data protection solutions. All those vendors talked about innovation and differentiation (and they were right), but it made solution designs and support challenging not just for IT teams, but for partners and vendors. What if someone had suggested a common layer for backup software, storage hardware and applications?

Actually, someone did. With Windows as the primary OS, and Exchange and

SQL Server as key applications that would benefit, Microsoft introduced Volume

Shadow Copy Service (VSS) several years ago to enable that common layer from within the Windows OS. Backup software vendors now include VSS requesters in their agents, hardware vendors include VSS providers and application vendors can now use VSS writers. Adoption was slow initially, but now almost every Windows application uses VSS—and everyone benefits. A common layer for backup software and storage hardware to interoperate happened once for application backups. Let’s hope it will happen again for deduplication. n

Cloud has a silver lining for ROBO storage

Providing and managing storage for remote and branch offices can be a challenge, but a hybrid approach using local and cloud-based storage may be the best solution.

S

TORAGE MANAGERS KNOW

that providing great data storage services to remote or branch offices (ROBOs) isn’t simply a matter of replicating a single, small office solution or extending data center storage to each ROBO with a WAN. But some vendors still insist that their traditional storage and data protection products can easily extend to cover ROBO needs, perhaps with just a few add-ons, a third-party product or two, and a bit of custom scripting. What they don’t mention is how quickly costs can climb, how tough management can be, and what to do with users who aren’t happy about compromising performance, accessibility or protection.

But there is hope. At Taneja Group, we’ve seen a couple of key trends that bode well for ROBO storage. First, cloud-based and cloud-enabled services are providing new opportunities to rethink and redesign storage services for distributed and mobile use cases. ROBOs are by definition distributed, and their users tend to be highly mobile. Second, some vendors are taking advantage of cloud services to build specific products to address ROBO storage challenges .

ROBO STORAGE ISSUES

ROBOs can range from a single user to a few dozen users, and some may even have 100 users or more. We estimate that there are more than 10 million

ROBOs worldwide, and that number is growing steadily. Some of the storage challenges that ROBOs contend with include:

● ●

Scalability. Storage capacity and use tends to grow in most ROBOs over time, and the data protection process and associated secondary storage must scale accordingly.

● ●

Manageability and reliability. Typically, ROBOs lack storage and data protection expertise and resources, and remote management of storage provisioning and data protection across a number of ROBO servers and user devices can be cumbersome and error prone.

● ●

Collaboration and sharing. ROBO users often need to share files within and among branches. ROBO users who rely on local branch infrastructure usually won’t be able to share data and collaborate with local colleagues or other sites.

● ●

Cost. The total cost of a full ROBO storage solution includes hardware and software, floor space, power and cooling at each site, and setting up and managing the local storage and data protection. Costs creep in for any additional

“local” elements, as well as for growing complexities in centralized management and operations.

In addition to these inherent challenges, backup agent overhead, slow WANspeed recovery times and distributed security are sources of concern with traditional ROBO storage approaches . Traditional approaches are local offerings that include physical storage at the ROBO, or centralized solutions that employ caching/accelerators to access remote storage at a data center, or in a private or public cloud.

LOCAL STORAGE FOR ROBO

s

The most popular approach has been to deploy a Windows file server or NAS device for local physical storage with backup to local tape (or disk) drives, and offsite backup or replication for disaster recovery. Endpoint devices are backed up locally or remotely to a data center or cloud. This approach provides highly accessible primary storage, but it relies on local users to manage backups and, considering cost and manageability, it can’t scale to many ROBO sites.

CENTRALIZED STORAGE

The other major approach is to allocate storage centrally out of a data center or cloud, and provide access to it over the WAN via some form of cache or accelerator. Local application servers and user endpoint devices are backed up remotely, using agents that are compatible with the caching solution. This method reduces local storage costs and provides some level of centralized management, but it creates a huge dependency on the WAN, is complex to deploy and can reduce storage access performance.

CLOUD-ENABLED ROBO STORAGE

We believe the ideal ROBO storage offering should combine the performance and feel of local storage with the scalability, resilience, manageability and economies of a central data center or cloud. A CTERA Networks Ltd. Cloud Storage

Enablement suite is an example of this approach. CTERA’s offering provides a local ROBO appliance that functions as both local NAS storage and as a cloud gateway . ROBO users get LAN-speed storage, but all files are deduped, compressed, encrypted and replicated to a private or public cloud for data protection. Local applications, servers and users can continue to leverage local backup, while also getting off-site data protection. What marks this as a welldesigned ROBO solution are the cross-ROBO file-sharing and synchronization features provided by the same components and connections.

There are certainly other ways to leverage cloud services for ROBOs, such as piecing together best-of-breed offerings perhaps using Huddle for collaboration, Riverbed’s Granite storage for local performance and Mozy for end-user cloud backup. But purpose-built, cloud-enabled ROBO storage products offer centralized management over large-scale ROBO deployments. Ultimately, the costs to deploy and operate prepackaged cloud-enabled storage, or storage appliance “gateways,” across hundreds of ROBOs can be far less than using traditional or piecemeal storage approaches.

If you’re looking for a storage offering that must scale to tens, hundreds or even thousands of ROBO sites, cloud-enabled storage should be on your shortlist of alternatives. n

SNAPSHOT

Use of cloud backup services expanding

Cloud backup is one of the oldest cloud storage services around, but it’s only in the past couple of years that it’s grown up enough to be seriously considered by enterprises. Approximately two-and-a-half years ago, our survey showed that 24% of companies were using cloud-based backup , but today that number is up to 41%. Those users trust the cloud, too, as 72% are confident enough to ship their primary data backups to the cloud .

It’s also being used as a BYOD antidote with 40% using cloud-based backup services to back up laptops, phones and tablets. Most users (70%) rely on a cloud service provider for software to send their data into the ether. But our respondents don’t put all their backup eggs in one basket: 35% use multiple cloud backup services, with an overall average of 1.7 services per user. How much do they actually use it? Cloud backup users have an average of 13 TB of data in the cloud, representing about 37% of their total backup volume. Eightyeight percent say they’re either satisfied or very satisfied with their cloud-based backup services experiences . —Rich Castagna
