Storage-System Hardware

The storage systems attach to the server and the interconnect components as described in Chapter 1. To review the installation types:

• Unshared direct , with one server, is the simplest and least costly;

• Shared-or-clustered direct , with a limit of two servers, lets two servers share storage resources with high availability; and

• Shared switched , which has two switch fabrics, lets two to 15 servers share the resources of several storage systems in a storage area network (SAN).

For FC4700 storage systems, at least one network connection is required.

Hardware for FC4700 Storage Systems

The primary hardware component for FC4700 storage is a ten-slot disk-array processor enclosure (DPE) with two storage processors

(SPs). Each FC4700 SP has two ports (front-end ports for server or switch connection) and two back-end buses that run the disks.

A DPE can support up to nine separate 10-slot enclosures called disk array enclosures (DAEs) for a total of 100 disks.

Storage Hardware — Rackmount DPE-Based Storage Systems

The DPE rackmount enclosure is a sheet-metal housing with a front door, a midplane, and slots for the storage processors (SPs), link control cards (LCCs), disk modules, power supplies, and fan packs.

All components are customer replaceable units (CRUs) that can be replaced under power. The DPE rackmount model looks like the following figure.

The disks — available in differing capacities — fit into slots in the enclosure. Each module has a unique ID that you use when binding or monitoring its operation. The ID is derived from the enclosure address (always 0 for the DPE, adjustable on a DAE) and the disk module slot numbers.

EMC1829

Figure 6-4 Disk Modules and Module IDs

Storage Processor (SP)

The SP provides the intelligence of the storage system. Using its own proprietary software (called Base Software), the SP processes the data written to or read from the disk modules, and monitors the modules themselves. An SP consists of a printed-circuit board with memory modules (RIMMs), and status lights.

Each FC4700 SP has two front-end ports for server or switch connection, and two back-end buses that run the disks.

For high availability, a storage system comes with two SPs. The second SP provides a second route to a storage system and also lets the storage system use write caching (below) for enhanced write performance.

Storage-System Caching

Storage-system caching improves read and write performance for several types of RAID Groups. Write caching, particularly, helps write performance — an inherent problem for RAID types that require writing to multiple disks. Read and write caching improve performance in two ways:

• For a read request — If a read request seeks information that’s already in the read or write cache, the storage system can deliver it immediately, much faster than a disk access can.

• For a write request — the storage system writes updated information to SP write-cache memory instead of to disk, allowing the server to continue as if the write had actually completed. The disk write occurs from cache later, at the most expedient time. If the request modifies information that’s in the cache waiting to be written to disk, the storage system updates the information in the cache before writing it; this requires just one disk access instead of two.

EMC Fibre Channel Storage System Model FC4700 Configuration Planning Guide


6

Data in the cache is protected from power loss by a standby power supply (SPS). If line power fails, the SPS provides power to let the storage system write cache contents to the vault disks. The vault disks are standard disk modules that store user data but have space reserved outside operating system control. When power returns, the storage system reads the cache information from the vault disks, and then writes it to the file systems on the disks. This design ensures that all write-cached information reaches its destination.

Vault disks are independent of user data storage; a disk’s role as a vault disk has no affect on its data capacity or performance.

SP Network Connection

Each SP has an Ethernet connection though which the Navisphere

Manager software lets you configure and reconfigure the LUNs and

Storage Groups in the storage system. Each SP connects to a network; this lets you reconfigure, if needed, should one SP fail.

Planning Your Hardware Components

This section helps you plan the hardware components — adapters, cables, and storage systems and site requirements — for each server in your installation.

For shared switched storage or shared-or-clustered direct storage, you must use high-availability options: two SPs per storage system and at least two HBAs per server. For shared switched storage, two switch fabrics are required.

For unshared direct storage, a server may have one or two HBAs.

Components for Shared Switched Storage

The minimum hardware configuration required for shared switched storage is two servers, each with two host bus adapters, two Fibre

Channel switch fabrics with one switch per fabric, and two SPs per storage system. Two SPS units (standby power supplies) are also required. You can use more servers (up to 15 are allowed), more switches per fabric, and more storage systems (up to four are allowed).

Components for Shared-or-Clustered Direct Storage

The minimum hardware required for shared switched or shared-or-clustered direct storage is two servers, each with two host bus adapters, and one storage system with two SPs. You can use more storage systems (up to four are allowed).

Components for Unshared Direct Storage

The minimum hardware required for unshared direct storage is one server with two host bus adapters and one storage system with two

SPs.You can choose more storage systems (up to four are allowed).

Storage-System Management

Introducing Navisphere Management Software

Navisphere software lets you bind and unbind disks, manipulate caches, examine storage-system status and logged events, transfer control from one SP to another, and examine events recorded in storage-system event logs.

Navisphere products have two parts: a graphical user interface (GUI) and an Agent. The GUIs run on a management station, accessible from a common framework, and communicate with storage systems through a single Agent application that runs on each server. The

Navisphere products are

• Navisphere Manager, which lets you manage multiple storage systems on multiple servers simultaneously.

• Navisphere Analyzer, which lets you measure, compare, and chart the performance of SPs, LUNs, and disks.

• Navisphere Integrator, which provides an interface between

Navisphere products and HP OpenView, CA Unicenter, and

Tivoli.

• Navisphere Event Monitor, which checks storage systems for fault conditions and can notify you and/or customer service if any fault condition occurs.

• Navisphere failover software. Application Transparent Failover

(ATF) is an optional software package for high-availability installations. ATF software lets applications continue running after the failure anywhere in the path to a LUN: a host bus adapter, cable, switch, or SP. ATF is required for any server that has two host bus adapters connected to the same storage system.

Another failover product is CDE (Driver Extensions) software, which has limited failover features. CDE is included with each host bus adapter driver package.

• Navisphere Agent, which is included with each storage system, and Navisphere CLI (Command Line Interface), which lets you bypass the GUI and type commands directly to storage systems.

The Agent runs on any of several different platforms, including

Windows and popular UNIX platforms; the other products run on

Windows platforms only.



7

Using Navisphere Manager Software

Navisphere Manager software (Manager) lets you manage multiple storage systems connected to servers on a TCP/IP network. Manager offers extensive management features and includes comprehensive on-line help.

Manager runs on a management station, which is a Windows NT

®

or

Windows

®

2000 server. The servers connected to a storage system can run Windows 2000, Windows NT, or a UNIX operating system such as Sun Solaris. Servers connected to the SAN can run different operating systems.

Storage Management Worksheet

The following worksheet will help you plan your storage-system management environment. For each server, complete a section.

For anyone to manage a storage system connected to a server, that person’s username and hostname must be identified as privileged though Navisphere management software.

On the worksheet, complete the management station server hostname and operating system; then decide whether you want the

Navisphere Analyzer and/or Event Monitor and, if so, mark the appropriate boxes. Then write the name of each managed server, with operating system, Storage Group, and manager user@host names.

You can copy much of the needed information from the LUN and

Storage Group planning worksheet in Chapter 5.

The Storage Group feature is provided by EMC Access Logix software.

Access Logix is required for all shared installations (shared switched or shared direct), but optional for unshared direct installations. If you don’t need Storage Groups and Access Logix, then on the LUN and Storage Group worksheet, skip the Storage Group entries.
