CHAPTER 2

SAN Configurations

This chapter introduces the components that you can include in your Storage Area Network (SAN). It also explains the different operating system environments and configurations that you can use in your SAN.

SAN Components

Servers

In a SAN, servers provide the attached client systems with access to high throughput, reliable storage systems. Servers also manage the storage systems and attached SAN appliances.
When you are installing, configuring, managing, or maintaining a server in a SAN, you must consider both the installed operating system, software, and storage that is beingusedonorbythatserver.

Server Software
The server software that is required on each server varies by the type of storage sys­tem it is using and by whether it is using a SAN Appliance.
Servers Accessing Storage Systems Directly
Ensure that each host server that is only accessing storage systems directly and through a PowerVault 530F SAN appliance, such as the server in Figure 2-1, has the following software installed:
not

Host Bus Adapters
Within a SAN, a host bus adapter (HBA) provides the connectivity from the host com­puter system to the external Fibre Channel device or to a PowerVault 50F, 51F, or 56F switch. The following HBAs are supported.
QLogic QLA2100, QLA2100F, QLA2200, and QLA2200F
The QLA2 nent Interconnect (PCI) 2.1 interface (fully backward compatible with 32-bit PCI). The QLA2100 and QLA2200 support copper media. The QLA2100F and QLA2200F sup­port fiber-optic media. For additional information about HBA cabling, see Appendix A, Cable Types.
QLogic QLA2200/66 and QLA2200F/66
The QLA2200/66 series HBAs support a 66-MHz, 64-bit PCI interface (fully backward­compatible with 32-bit PCI). The QLA2200/66 supports copper media. The QLA2200F/66 supports fiber-optic media. For additional information about HBA cabling, see Appendix A, Cable Types.

PowerVault Fibre Channel Switches

Dell PowerVault Fibre Channel switches are used for building and managing a SAN. The PowerVault 50F and 51F are 8-port Fibre Channel switches, and the PowerVault 56F is a 16-port Fibre Channel switch. The switch is a key component of a SAN. The switch’s primary function is to enable true switched Fibre Channel fabric configura- tions. The PowerVault Fibre Channel switches are necessary for PowerVault 650F, 651F, and 660F storage system configurations that include more than two servers.
In a fully redundant SAN configuration, at least two switches are required. Each switch connects to one of the storage controllers in the PowerVault 650F, 651F, or 660F storage system, which allows all servers connected to the switch to access all logical unit numbers (LUNs) bound on that storage controller. This why each server must have two HBAs installed. Each HBA is connected to one switch and to one stor­age controller. Due to the failover capabilities provided by the Dell OpenManage Application Transparent Failover (ATF) software for 650Fs and 651Fs and by QLogic QLDirect for 660Fs, this configuration eliminates cables, switches, gigabit interface converters (GBICs), and HBAs as single points of failure. If any one of these hardware components fails, connectivity is maintained with no loss of data. The switch also allows you to add and remove devices while the SAN is operational.

PowerVault 650F and 651F Disk Processor Enclosures

The PowerVault 650F storage system is a Fibre Channel-attached, external redundant array of independent disks (RAID) subsystem. The configuration is expandable to 120 hard-disk drives with additional PowerVault 630F disk array enclosures (DAEs). Each 650F and 630F supports up to 10 hard-disk drives. This configuration supports one 650F and up to 11 630Fs connected through link controller cards (LCCs). Standard fea­tures include redundant power supplies, fans, and LCCs.
support.dell.com
The PowerVault 651F is a stand-alone deskside enclosure. The enclosure contains a PowerVault 650F DPE and a PowerVault 630F DAE, which together provide a maxi­mum of 20 hard-disk drives.

PowerVault 660F and 224F Storage Systems

The PowerVault 660F storage system is a Fibre Channel-attached, external RAID stor­age system. The configuration is expandable to 112 hard-disk drives with additional PowerVault 224F storage enclosures. Each 660F and 224F supports up to 14 hard-disk drives. This configuration supports one 660F and up to seven 224Fs connected through input-output (I/O) expansion modules. Standard features include redundant power supplies, fans, I/O expansion cards, and loop resiliency circuit/SCSI enclosure services (LS) modules.

PowerVault 35F Fibre Channel Multiport Bridge

The PowerVault 35F Fibre Channel multiport bridge is a small computer system inter­face (SCSI)-to-Fibre Channel protocol converter that enables SCSI-based high-voltage differential (HVD) tape libraries and autoloaders, such as the PowerVault 130T DLT4000 or DLT7000 library or 120T DLT4000 or DLT7000 autoloader, to be attached to the Fibre Channel fabric and to be shared between multiple servers in the SAN.
SAN Configurations 2-5
Page 6

PowerVault 130T Library and 120T Autoloader

The PowerVault 130T library is a compact, tape-based, HVD SCSI-2 storage sub­system for data backup and restore for one or more servers and disk storage subsystems. Referred to as a tape library, the PowerVault 130T features high capacity, high throughput, data compression, automated backup capability, and reliable, accu­rate data restore functions.
The PowerVault 120T DLT400 0 and DLT7000 autoloaders are fully automated, seven­tape, random-access tape autoloaders that are designed to be more effective network backup solutions than manually operated stand-alone tape drives.

PowerVault 530F SAN Appliance

The Dell PowerVault 530F is a SAN appliance that offers a variety of functions, depending on customer needs and application requirements. The primary function of the PowerVault 530F is local and remote data mirroring for disaster recovery and data replication. In addition, the system features Snapshot Copy, LUN masking, mapping and partitioning, as well as the ability to boot a server through the PowerVault 530F system.
For more information on PowerVault 530F features, refer to the documentation that came with your system.

Supported SAN Configurations

A Dell SAN supports consolidation of storage for Microsoft Windows NT and Windows 2000, both clustered and non-clustered, and consolidation of storage for Novell NetWare. Each of these operating system environments are supported on independent SANs or in separate zones on the same SAN. PowerVault 530F SAN appliances can exist on the same SAN.

or the
The Dell OpenManage Storage Consolidation software does not support NetWare vol­umes. A Dell SAN requires the administrator to manually control the mounting of SAN volumes on each NetWare server.
Table 2-2 lists the maximum number of devices supported in NetWare SAN configurations.
NOTICES: For volumes to be accessed by a NetWare server, the server must mount them. You can mount them by issuing the Mount command; however, most administrators place the command in the autoexec.ncf file. After Net­Ware installation, the Mount all command is placed in the autoexec.ncf file by default. The administrator must remove this command and replace it with a series of Mount commands explicitly mounting each of the volumes on the SAN that should be available to the server. For instructions, see Chapter 12, “Installing, Configuring, and Uninstalling Components in a Novell NetWare SAN.”
2-8 Dell PowerVault SAN Administrator’sGuide
Page 9
If you are using Novell Storage Services (NSS) volumes in your SAN, you must edit each system’s autoexec.ncf file. In this file, find the command
load nss.nlm and change it to LOAD NSS /AutoDeactivateVolume=all /Mail­boxSize=16000 /ClosedFileCacheSize=100000 /CacheBalance=60. This
command prevents the NSS manager from mounting all NSS volumes attached to the SAN.

Heterogeneous SAN Configurations

Heterogeneous SANs are SANs that include multiple operating system environments. Each operating system environment must be in a separate zone. However, Windows NT and Windows 2000 servers can reside in the same or separate zones. NetWare servers must reside in a separate zone, each PowerVault 530F configuration must reside in a separate zone, and each MSCS cluster pair must reside in a separate zone.
Table 2-4 lists the maximum number of devices that are supported in a single hetero­geneous SAN configuration.
NOTE: Windows servers, Windows NT MSCS cluster pairs, Windows 2000 MSCS cluster pairs, and NetWare servers must all be in separate fabric zones. NetWare servers cannot share the same storage systems with Windows servers or MSCS cluster pairs. Windows NT and Windows 2000 servers can share the same zone and storage systems. Although Windows servers and MSCS cluster pairs must be in sep­arate zones, they can share the same storage system, but not the same LUN.

Getting the Connected Device WWNs Using the PowerVault 5xF Fibre Channel Switch Name Server Table

Zoning is required in heterogeneous SAN configurations to separate incompatible environments, such as separating Windows environments and storage from NetWare environments. It may be used in other configurations depending on the components and environments in your SAN. Zoning uses World-Wide Names (WWNs) to uniquely identify each target device in a SAN.
YoucanobtaintheWWNsofdevicesthatareconnectedtoeachswitchbyusingthe nsShow command through a Telnet or serial session. This command lists the con­tents of the name server table in the switch. The list of WWNs are sorted by the physical port number to which the devices are connected. (The position in the name server table listing does not identify the physical port to which the device is con­nected.) The WWN listing shows both the port and node WWNs. This method of obtaining the WWNs is recommended if the fabric contains only PowerVault 50F switches; however, it can be used for PowerVault 51F and 56F switches as well.
In a fabric with a PowerVault 51F or 56F switch (running version 2.1. name server information for the entire fabric can be accessed from the Dell PowerVault Switch Manager application program using a Web browser.
