Moving to new servers and storage can bring myriad benefits to your
business, from saving space to running more applications. But when
you’re considering an upgrade, how do you know which new solution is
right for you?
In the datacenter at Principled Technologies, we compared a bare-metal
legacy solution with a new solution featuring Intel processor-powered Dell
PowerEdge R730 servers, a VMware vSphere 6 virtual environment, and
Dell Storage SC4020.
Both solutions ran the same mixed workload of database, email,
and simulated file server work, but the upgraded solution handled a
staggering 18 times the work of the older one. That means you can
consolidate many workloads from multiple user groups or departments.
You can also do significantly more work in the same amount of
rack space, leaving room in the datacenter for growth, and can use
virtualization to maximize the value of your resources.
Do the work of
18 legacy solutions
We used the Dell Performance Analysis Collection Kit
(DPACK) to evaluate and understand the performance
of the new environment. By running DPACK in your own datacenter, you can
characterize your environment’s performance and identify bottlenecks.
Then, take a look at the DPACK results for our newer solution to see its
performance metrics. In your environment, using DPACK can highlight
upgrade opportunities and help you better understand specific
performance requirements.

Your time to upgrade
Legacy infrastructure woes
As they get older, legacy infrastructures may struggle to keep up with the growth of business. Components in legacy
hardware can degrade and begin to malfunction from use over time. What’s more, legacy hardware lacks new processors
that can speed up applications; new designs that can lower power consumption; and new, effective management
features that can save time for IT staff and reduce downtime for users.
Do more work in the same space
In hands-on work in our datacenter, we determined that by upgrading from a legacy solution to the new Intel processorbased Dell PowerEdge R730 and VMware vSphere solution, you could do 18 times the work without taking up any more
rack space. By completing so much more work in the same amount of space, your company can consolidate workloads
from multiple departments. For instance, we centralized multiple Exchange mail servers, SQL databases, and file
servers into one location while keeping them separate on VMs. At the same time, your business can grow without costly
datacenter expansions.
Take full advantage of your resources
Virtualizing with VMware vSphere can help you maximize the value of your newer, more powerful hardware and better
utilize compute, networking, and storage resources that would otherwise go unused. It gives you a more efficient
environment and more control over precisely how your applications utilize your newly increased resources. With this
control, you can use a single server to run multiple workloads, each of which might have maxed out a single server in
your legacy environment.
Your current infrastructure may already be fully or partially virtualized, or you may be working with a bare-metal
environment. Whatever your starting point, VMware vSphere can help you make the most of your investment in an
upgraded environment.

Keep your favorite parts of your
current infrastructure
By moving to newer physical servers
and centralized storage, you gain the
benefits of the latest technologies while
maintaining the hardware features on
which you rely, including the flexibility of
general‑purpose servers and centralized
storage features such as snapshots and
compression. At the same time, your
company has new opportunities for added
density, faster workload processing, and
better resource management.
This solution also enables you to
use a management tool that may
already be familiar to your IT staff: Dell
OpenManage™ Essentials (OME). If you
were previously using OME to manage a Dell server and storage infrastructure from five or six years ago, the new version
of OME will allow you to manage your new servers in a similar way to how you managed your old ones. Newer hardware,
such as the Dell PowerEdge R730 powered by Intel Xeon processors, can take advantage of the new features and
functions in the latest version of OME while maintaining the familiar management interface your IT administrators may
already use. In previous studies, we found OME can save time and improve efficiency in datacenter management.1 These
advantages may help enable a more straightforward transition from the old hardware to the new.
Take a look at DPACK
DPACK measures the throughput, disk I/O, memory, capacity, and CPU utilization of your servers and storage. Its reports
present this data to help you better understand what hardware you’ll need when you upgrade.
Using the DPACK online viewer, you can review your results in two ways: Aggregate or Individual. Aggregate results offer
performance data for the full environment, while Individual results provide numbers for a specific server. When we ran
DPACK on the new Dell and VMware solution, we viewed Aggregate results.
In addition to simply running DPACK in your own environment, you can contact a Dell salesperson who can help you
interpret your DPACK results and size your upgraded environment. We did not test this service.

How we navigated the path to an upgraded datacenter
Our legacy environment
We created our legacy solution to approximate an infrastructure that a small enterprise might have
purchased five or six years ago and still use today. This bare-metal (non-virtualized) environment
contained three Dell PowerEdge R710 legacy servers with one legacy Dell EqualLogic™ PS6110
storage array. Appendix C has complete details on the solution.
Our upgraded environment
Our upgraded environment represents
a possible next step for an enterprise
moving from the legacy environment we
chose. It contains newer products with an
architecture and functionality similar to
those in the legacy environment.
Our new solution contained three Dell
PowerEdge R730 servers powered by Intel
Xeon processors E5-2660 v4 and one allflash Dell Storage SC4020 array powered
by an Intel Xeon processor E3-1265L v2.
We utilized VMware vSphere 6 for the
hypervisor with VMware vCenter Server™
and VMware vRealize® Operations
Manager™ for hypervisor management.
This tool provides customizable
dashboards you can use to analyze risk,
monitor capacity issues, and check on
your virtual environment’s health. See
Appendix C for more details.
What we did
On the legacy environment, each application of the mixed workload had a dedicated server. We tuned each application
to its maximum performance while maintaining acceptable thresholds for storage latency—a measure of how fast storage
can complete a request. For our purposes, those thresholds were under 20ms.
Then, we virtualized all legacy application servers on the upgraded solution and increased the number of VMs in sets
until we reached 80 percent utilization of at least one hardware resource. In this case, that was storage capacity and
allocated RAM. With additional storage capacity and RAM, you could potentially obtain an even higher consolidation
ratio because CPU and storage latency thresholds were not at full capacity.
To capture data on the upgraded environment’s performance, we ran DPACK. (For our DPACK results, see Appendix D.)
Run more applications without expanding your datacenter
August 2016 | 4
Our workloads
We generated the workloads for each application using industry-standard tools.
For a database workload, we chose Microsoft® SQL Server® 2014 running the
DVD Store 2 benchmarking tool; for email, we chose Microsoft Exchange 2013
running a Microsoft Exchange Load Generator 2013 workload; and for simulated
file server, we chose the Iometer tool, which generates synthetic data streams
mimicking a file server workload.
This mixed workload may reflect many companies’ operations. In a traditional
legacy setup, IT may assign a single application to a single server. That
application uses the hardware resources it needs, but the rest of the server’s
resources are wasted. This problem grows with the company; as the organization
splits into multiple departments with distributed IT staff, it can get even worse.
With a virtualized solution like the one from Dell, Intel, and VMware, IT can
consolidate multiple different workloads onto virtualized clusters, making the
most out of their storage and compute resources and letting fewer resources go
to waste.
DVD Store 2
We used DVD Store Version 2.1, or
DS2.2 DS2 is a database performance
tool. It models an online store where
customers log in, search for products,
and make purchases. It also performs
other actions, such as adding new
customers, to exercise a wide range of
everyday database functions.
Conclusion
By upgrading from the legacy solution we tested to the new Intel processorbased Dell and VMware solution, you could do 18 times the work in the same
amount of space. Imagine what that performance could mean to your business:
Consolidate workloads from across your company, lower your power and
cooling bills, and limit datacenter expansion in the future, all while maintaining a
consistent user experience—the list of potential benefits is huge.
Try running DPACK, which can help you identify bottlenecks in your environment
and inform you about your current performance needs. Then consider how the
consolidation ratio we proved could be helpful for your company. The Intel
processor-powered Dell PowerEdge R730 solution with VMware vSphere and
Dell Storage SC4020, also powered by Intel, could be the right destination for
your upgrade journey.
Microsoft Exchange Load
Generator 2013
Microsoft Exchange Server is an email
application that businesses use widely
across multiple industries. To test
how well the solutions could run an
Exchange server workload, we used
Microsoft Exchange Load Generator
2013 (LoadGen), which functions as
a sample Exchange workload and
simulates a large number of users
generating email activity.3

Many businesses use file servers, so
we simulated a file server workload
using Iometer 1.1.4 Iometer uses action
profiles to perform input/output (I/O)
operations that approximate data
operations such as reading files, writing
files, and updating files.

Configuring the Microsoft SQL Server 2014 server
For the legacy environment, we created large dedicated LUNs on the Dell EqualLogic PS6110 for the SQL database,
logs, and backup. For the upgraded VMware environment, we added a 60GB VMDK for the database, a 30GB VMDK for
logs, and a 50GB VMDK for backup to the SQL VM using the Dell Storage SC4020 datastore.

Generating the DVD Store 2 data
We generated the data using the Install.pl script included with DVD Store version 2.1 (DS2), providing the parameters
for our 40GB database size and the Microsoft SQL Server 2014 platform. We ran the Install.pl script on a utility system
running Linux.® The Install.pl script also generated the database schema.
After processing the data generation, we transferred the data files and schema creation files to a Windows-based system
running SQL Server 2014. We built the 40GB database in SQL Server 2014, then performed a full backup, storing the
backup file on the SQL backup LUN for quick access. We used that backup file to restore the server between test runs.
The only modifications we made to the schema creation scripts were the specified file sizes for our database. We
explicitly set the file sizes higher than necessary to ensure that no file-growth activity would affect the outputs of the
test. Apart from this file size modification, we created and loaded the database schema according to the DVD Store
documentation. Specifically, we followed these steps:
1. Generate the data and create the database and file structure using database creation scripts in the DS2 download. Make size modifications specific
to the 40GB database and the appropriate changes to drive letters.
2. Transfer the files from a Linux data generation system to a Windows system running SQL Server.
3. Create database tables, stored procedures, and objects using the provided DVD Store scripts.
4. Set the database recovery model to bulk-logged to prevent excess logging.
5. Load the generated data into the database. For data loading, use the import wizard in SQL Server Management Studio. Where necessary, retain
options from the original scripts, such as Enable Identity Insert.
6. Create indices, full-text catalogs, primary keys, and foreign keys using the database-creation scripts.
7. Update statistics on each table according to database-creation scripts, which sample 18 percent of the table data.
8. On the SQL Server instance, create a ds2user SQL Server login using the following Transact-SQL (T-SQL) script:
USE [master]
GO
CREATE LOGIN [ds2user] WITH PASSWORD=N’’,
DEFAULT_DATABASE=[master],
DEFAULT_LANGUAGE=[us_english],
CHECK_EXPIRATION=OFF,
CHECK_POLICY=OFF
GO
9. Set the database recovery model back to full.
10.Create the necessary full text index using SQL Server Management Studio.
11.Create a database user and map this user to the SQL Server login.
12.Perform a full backup of the database. This backup allows a restore of the database to a pristine state relatively quickly between tests.

Appendix C – Our setup
Legacy environment
For our legacy environment, we configured three identical Dell PowerEdge R710 servers. Each server contained 48
GB of RAM and dual Intel Xeon E5520 processors. We installed Windows Server 2012 R2 with updates on each server
and configured each server for its individual workload purpose. For the database workload server, we installed SQL
Server 2014 SP1 with updates and configured a single SQL instance with a 40GB database for the DVD Store 2 server
to target. For the mailbox workload server, we installed Microsoft Exchange 2013 with updates. We then generated a
typical 500-mailbox environment using a Load Generator 2013 client. Finally, we configured the file server with Iometer
and configured it to act as the Active Directory server for the Exchange environment. We cabled all three servers to a
standard 1Gb Ethernet switch using the onboard NICs for client and management traffic. For information on our test
methodology, see Appendix B.
For the backing legacy storage, we configured a Dell EqualLogic PS6110 array with 24 10K HDDs and 10Gb iSCSI
connectivity. We cabled each of the EqualLogic’s controllers to a 10Gb Dell Networking S4810 switch with redundant
paths. We then installed an Intel Ethernet Server Adapter X520 in each PowerEdge R710 and cabled both ports on each
card to the S4810. We then configured each port for iSCSI traffic and multipath I/O using native Windows tools and the
EqualLogic HIT Kit software. We presented each server with individual LUNs on the EqualLogic PS6110 for their specific
workloads: three LUNs for the SQL database, logs, and backups to the database server; three LUNs for the Exchange
mailbox database, logs, and backups to the mailbox server; and one LUN for the Iometer work file to the file server. See
below for a detailed diagram of our legacy environment test bed.

Upgraded environment
For our upgraded environment, we configured three identical Dell PowerEdge R730 servers. Each server contained
256 GB of RAM and dual Intel Xeon E5-2660 v4 processors. We installed VMware vSphere 6 Update 2 on each server
and created a three-node cluster in VMware vCenter Server. We cabled each server to a standard 1Gb switch using the
onboard 1Gb NICs for client, management, and VM traffic. Additionally, we cabled the onboard 10Gb NICs to a Dell
Networking S4810 switch for vMotion traffic. We configured all networks using VMware best practices.
For the backing storage, we configured a Dell Storage SC4020 array with twelve write-intensive SSDs and twelve mixedused SSDs. For storage connectivity, we connected two 8Gb fibre channel ports from each of the two storage controller
modules to a Brocade 300 fibre switch with NPIV enabled. We then installed a QLogic GLE2562 8Gb fibre channel card
in each PowerEdge R730 and cabled both ports to the Brocade switch. We created a single 18TB LUN on the storage
and mapped the LUN to the PowerEdge R730 servers for VM storage with read and write cache enabled on the storage.
See below for a detailed diagram of our upgraded environment test bed.

Each server hosted a mix of database workload VMs, mailbox workload VMs, and file workload VMs, with each VM
matching the software configuration of the legacy servers. With load-balancing, each PowerEdge R730 ran six sets of
legacy workload VMs. We resized the VMs resources lower than the legacy environment servers to allow for maximum
resource utilization and workload consolidation because our test VMs were performing at the level of the legacy
environment or better. We also reserved all RAM for each VM to avoid memory contention. All VMDKs were thick
provisioned eager zeroed. For each VM type, we used the following VM hardware settings:

Appendix D – DPACK data
While we were testing, we ran DPACK on the upgraded Dell and VMware environment. Below are screenshots of
the DPACK reports covering an hour-long test run in which the new solution is doing 18 times the work of the legacy
solution. We used this data for the performance analysis of our test runs, specifically CPU, IOPS, and storage latency.
CPU
In the screenshot below, the upgraded environment achieved a peak CPU of 52.7 percent with an average of
approximately 33 percent at a steady state. Storage capacity became our bottleneck. If we had added more storage
capacity, we could have provisioned additional VMs on each host to get the most out of the compute resources because
this environment was virtualized.
IOPS
The upgraded environment with the all-flash array peaked at 17,576 IOPS during our testing.

Latency
Though the upgraded environment hit a peak of 56.7ms read and 25.1ms write latency early during the Exchange
workload ramp-up, the latency during a steady performance state remained fairly even, at approximately 5ms write and
9ms read latency.

Additional DPACK counters
DPACK also provides many other graphs showing metrics like memory utilization, network and storage throughput, I/O
size, and more. We did not use these graphs in our analysis. When you examine all the graphs together, the data they
provide can give you a clear picture of your current environment’s performance needs as well as potential bottlenecks
and limitations.
