Except as provided in Intel's Terms and Conditions of Sale for such products, Intel assumes no liability whatsoever, and Intel disclaims any express or implied warranty, relating to sale and/or use of Intel® products including liability or warranties relating to fitness for a particular purpose, merchantability, or infringement of any patent, copyright or other intellectual property right. Intel products are not designed, intended or authorized for use in any medical, life saving, or life sustaining applications or for any other application in which the failure of the Intel product could create a situation where personal injury or death may occur. Intel may make changes to specifications and product descriptions at any time, without notice.

Intel® server boards contain a number of high-density VLSI and power delivery components that need adequate airflow for cooling. Intel's own chassis are designed and tested to meet the intended thermal requirements of these components when the fully integrated system is used together. It is the responsibility of the system integrator that chooses not to use Intel developed server building blocks to consult vendor datasheets and operating parameters to determine the amount of airflow required for their specific application and environmental conditions. Intel Corporation can not be held responsible if components fail or the server board does not operate correctly when used outside any of their published operating or non-operating limits.

Warnings

Heed safety instructions: Before working with your server product, whether you are using this guide or any other resource as a reference, pay close attention to the safety instructions. You must adhere to the assembly instructions in this guide to ensure and maintain compliance with existing product certifications and approvals. Use only the described, regulated components specified in this guide. Use of other products / components will void the UL listing and other regulatory approvals of the product and will most likely result in noncompliance with product regulations in the region(s) in which the product is sold.

System power on/off: The power button DOES NOT turn off the system AC power. To remove power from system, you must unplug the AC power cord from the wall outlet. Make sure the AC power cord is unplugged before you open the chassis, add, or remove any components.

Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power, telephone, and communication cables. Turn off the server and disconnect the power cord, telecommunications systems, networks, and modems attached to the server before opening it. Otherwise, personal injury or equipment damage can result.

Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, boards, and other parts. It is recommended that you perform all procedures in this chapter only at an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground any unpainted metal surface on your server when handling parts.

ESD and handling boards: Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After removing a board from its protective wrapper or from the server, place the board component side up on a grounded, static free surface. Use a conductive foam pad if available but not the board wrapper. Do not slide board over any surface.

Installing or removing jumpers: A jumper is a small plastic encased conductor that slips over two jumper pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle nosed pliers. If your jumpers do not have such a tab, take care when using needle nosed pliers to remove or install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper, or you may bend or break the pins on the board.

Storage System Management Ports

The storage system can have two management ports, one per storage processor (SP). Plan the network and security characteristics for each management port and record the data below. Your network administrator should provide this information.

Provide a static IP address for each storage system MANAGEMENT port.

SP A MANAGEMENT port ______.______.______.______

SP B MANAGEMENT port ______.______.______.______

Subnet mask ______.______.______.______

Default gateway ______.______.______._____

Provide a username and password for your storage system.

Username ________________________

Password ________________________

Definitions

IP address The static network IP (Internet Protocol) address (for example, 128.222.78.10) for communication with a management port of a storage processor (SP A or SP B). There is one management port per SP.

Subnet mask The subnet mask for the local area network (LAN) to which the storage system is connected for management, for example, 255.255.255.0.

Gateway The gateway address for the LAN to which the storage system management port is connected.

Username A valid username for logging in to the management interface must start with a letter and may contain 1 to 32 letters and numbers. The name may not contain punctuation, spaces, or special characters. You can use uppercase and lowercase characters. Usernames are case-sensitive. For example, ABrown is a different username from abrown.

Password A password for logging in to the management interface may contain 1 to 32 characters, consisting of uppercase and lowercase letters and numbers. As with the username, passwords are case-sensitive. For example, Azure23 differs from azure23. The password is valid only for the username you specified.

Fibre Channel Switch Information

If your configuration will use one or more Fibre Channel switches, complete a Switch information worksheet for each switch. If your site will not use switches, skip this section, and continue with "Storage System Disk Information" on page 6.

Customer-installable SSR212PP-Series switches are easily configured (some are preconfigured) so any HBA connected to switch ports other than 0 and 4 communicates with storage processors connected to switch ports 0 or 4. With switches set up in such "hard zones," you can connect FE 0 or FE 1 to ports 0 and 4 only, and connect HBAs only to ports 1, 2, 3, 5, 6, or 7...16.

Completing the Switch Information Worksheet

On the worksheet, for each switch port, indicate the SP or HBA port to which the switch port will connect.

SP-to-Switch Connections

Specify the SP-to-switch connections. For preconfigured switches, ports 0 and 4 are the only two switch ports you can connect to storage system SP ports; if you will use both switch ports, specify connections for each. These identify the SP (A or B) and the SP port (labeled FE 0 or FE 1) that you will connect to each switch port.

Switch-to-Server-HBA Connections

Specify switch-to-server connections here for any of the switch ports (1, 2, 3, 5, 6, 7...16 in preconfigured, switches) that you will connect to a server HBA. Specify the server name and HBA name, if you plan to the HBA using Navisphere¤ software.

If you have a second switch, specify the connections you will make to that switch.

Number (1-6 or spare)

You must create at least one disk pool for virtual disks. You can create up to four RAID 5 disk pools or six RAID 1/0 disk pools, numbered 1-6, in a storage system.

6

Intel Storage System SSR212PP User Guide

 

Revision 1.0

If your system has two SPs, you should create at least two disk pools, since the software assigns one or more disk pools to each SP; that is, it assigns disk pool 1 and all its virtual disks to SP A, disk pool 2 and all its disks to SP B, disk pool 3 and its disks to SP A, and disk pool 4 and its disks to SP B. If you create only one pool, all virtual disks in the storage system will be assigned to SP A.

Disks to form each pool

For each pool, specify the numbers of the disks you will include. The number of disks in a pool determines its capacity. Generally, we suggest no more than six; the minimum is three for RAID 5 and two for RAID 1/0 pools.

For maximum use of space on the disks, it is recommended that you do not combine disks 0 through 3 (the operating system disks) in a disk pool with other disks. Part of the space on the operating system disks is preloaded with system data, and as a result, is not available for your data. If you combine operating system disks in a disk pool with other disks, each of the other disks loses space for data equal to the system data space on an operating system disk.

If you have disks of differing capacities (for example, 250and 500-Gbyte), always use disks of the same capacity when creating a disk pool. If the disks have different capacities, the software will format each disk at the smaller of the two disk sizes, wasting more than 200 Gbytes of potential storage on each larger disk.

When you create disk pools, consider making one disk a hot spare. A hot spare allows your system to continue running with its normal performance and retain its redundancy if a disk fails. However, because a hot spare is reserved as a replacement disk, it cannot be used as a virtual disk. You may not want to devote an entire disk to maintaining redundancy after a disk failure.

If you create disk pools that use all the storage system disks, no space will remain for a hot spare. Later, if you need to create a hot spare, you must delete all the virtual disks in the disk pool, delete the pool, create a new pool, and then create the hot spare and new virtual disks on the new pool.

Always use a disk with the largest capacity as a hot spare. You can make any disk other than 0, 1, 2, or 3 a hot spare. If you decide to use a hot spare, write "Spare" in the appropriate row in column 1 and the disk number in column 2.

If you want to create disk snapshots, that is, capture point-in-time images of a virtual disk, then you must reserve disk space for snapshot disk resources. The snapshot resource uses this space transparently for snapshot operations, but the space must be available and not allocated to any virtual disk. The snapshot resource requires a maximum of 20 percent of each virtual disk whose point-in-time images you will capture, allocated in 10-Gbyte blocks. For example, if you will take snapshots of a 290-Gbyte virtual disk, leave 60 Gbytes of disk space unused. Twenty percent of 290 is 58, but space is given in 10-Gbyte blocks; therefore you must reserve 60 Gbytes.

From Disk 0 through Disk 11, select the disks that you want to include in the disk pool, and select a disk to be a Hot Spare. Record this information in the Storage System disk information worksheet.

Disk pool capacity (Gbytes)

To calculate the size of a RAID 5 disk pool, multiply the number of disks less 1 (n-1) by the disk capacity. For a RAID 1/0 disk pool, multiply the number of disks by the disk capacity, then divide by 2. The following table shows the formatted capacity of SSR212PP-Series disks.

 

250 Gbyte Disks

500 Gbyte disks

 

 

 

Disks 0-3

217 Gbytes per disk

458 Gbytes per disk

 

 

 

Disks 4-11

230 Gbytes per disk

445 Gbytes per disk

 

 

 

Name

Name the virtual disks in each disk pool. You can include up to 128 virtual disks in a disk pool. The default virtual disk name is Virtual Disk n, where n is the sequential number, starting with 1. However, you can substitute a more meaningful name, such as Users or Mail. You can choose to have multiple applications on the same virtual disk.

If you will have more than one disk pool, try to place the same number of virtual disks in each pool. Or, if you know that one or more virtual disks will be accessed often, you might choose to place these on their own SP. For example, you might place a heavily accessed virtual disk, such as a database, by itself on disk pool 2, attached to SP B; and place other, lightly accessed virtual disks in disk pool 1, attached to SP A.

Function

Describe the purpose of the virtual disk.

Virtual disk capacity (Gbytes)

Determine the capacity of each virtual disk in the disk pool. The combined capacity of all virtual disks cannot exceed the available space of the parent disk pool.

Decide how much space in the disk pool should be free space. Generally, you should leave a modest amount of free space, such as 10 percent of the disk pool size, in each pool. Then you can expand any of the virtual disks in the pool up to the amount of reserved space.

Free space (Gbytes)

Enter the amount of free space you want to reserve for expansion. Note this space is available to all virtual disks in the disk pool; that is, if there are multiple virtual disks in the pool, you can allocate part or all of the free space to one virtual disk or among several disks.

If you do not reserve adequate free space in a disk pool, and you need more space on a virtual disk in the pool, you must back up the data in the pool, destroy the pool, create a new pool with a larger virtual disk, and then reload the data.

Server to be assigned (assigned servers)

You will need to specify each assigned server when you create the virtual disk. Write the server hostname here. The maximum number of servers you can connect to one storage system is ten.

Introduction

SSR212PP-Series iSCSI storage systems connect to servers through Internet SCSI (iSCSI) interfaces. Storage systems and servers can connect directly from one iSCSI port to another, or through an IP (Internet Protocol) network. iSCSI host bus adapters (HBAs) or network interface cards (NICs) in the servers act as the physical iSCSI interfaces.

You must identify the network settings for each iSCSI I/O port in a storage system, including the IP address, subnet mask, and gateway address. These settings define the targets of input from the servers in your environment. You must also identify network settings for the iSCSI I/O ports in servers that connect to the storage system; these settings define the initiators of I/O between servers and the SSR212PP2i and SSR212PPi storage systems.

In some contexts, iSCSI documentation refers to the servers and storage systems themselves as initiators and targets, respectively.

Terminology

In this document, we use the terms initiator, target, server, and storage system as follows:

Initiator

A port on a NIC or iSCSI HBA that issues I/O requests to a target in the

 

storage system. NICs and HBAs are installed on the environment s

 

servers.

Target

A storage system port (target portal) that accepts and responds to requests

 

from an initiator. In iSCSI systems the targets, called front-end, or data,

 

ports, are on storage processors.

Server

A host connected (directly or through a network router or switch) to the

 

front-end (data) ports on SSR212PP-Series storage systems. A server can

 

also be a management station.

Storage system Your SSR212PP2i and SSR212PPi storage system.

iSNS

You can use the Internet Storage Naming Service (iSNS) on Windows platforms that are part of an iSCSI configuration. iSNS requires an iSNS server on the storage network and a client storage system; other hosts connected to the storage system are also iSNS clients.

The iSNS server acts as the repository where hosts and storage devices register their lists of initiators and targets. Each individual initiator or target registers its components with the iSNS server; the server then answers the initiator s queries for devices with the list of registered targets. Discovery domains implemented on the server restrict what targets an initiator sees.

CHAP

To prevent unauthorized access to the storage system, you can set up CHAP (Challenge Handshake Authentication Protocol) authentication for both the initiator and the target. For CHAP authentication, you specify a username and password (called a secret) that any initiator must use to connect to the target through the iSCSI ports; the target authenticates

16

Intel Storage System SSR212PP User Guide

 

Revision 1.0

the initiators. To increase the level of security, you can also set up mutual CHAP authentication where initiators authenticate targets, thereby ensuring that the correct initiators are connecting to the correct targets.

Planning worksheets

For each storage system that you will configure, complete a copy of the enclosed worksheets and store it in a safe location. While working with this document and planning your configuration, refer to the Tested Hardware and OS List (THOL) document the SSR212PP support website for storage system configuration rules and sample configurations.

CAUTION

All of your security efforts will be nullified if you leave any completed worksheets in public places. Store them in a secure place.

Intel Storage System SSR212PP User Guide

17

iSCSI Configuration Rules

Refer to this section as you plan your iSCSI environment with your network administrator. It provides minimal guidelines for configuring initiator servers and target storage systems in IP networks that use the iSCSI protocol. It is recommended to use discrete networks dedicated to iSCSI data traffic, but support other configurations.

CAUTION

The number and complexity of supported configurations is constantly growing. The rules and examples shown in this document are a subset of those in the more complete, current, and detailed Tested Hardware and OS List (THOL) document the SSR212PP support website.

Login Limitations

Initiator software

Supported logins

 

 

MIcrosoft iSCSI initiator

1 login per server to each SP data port

 

 

QLogic SANsurfer

1 login per HBA to each SP data port

 

 

Supported Network Devices

SSR212PP-Series storage systems support industry-standard switches and routers.

Initiators can connect to target iSCSI storage systems using a Layer 2 (switched) or Layer 3 (routed) network.

VLANs and/or VPNs in the network should be transparent to the storage system and are supported as long as the network quality is adequate.

Supported Server Devices

You can attach an SSR212PP-Series iSCSI storage system to Microsoft Windows 2000 and Microsoft Windows Server 2003 servers that run the native iSCSI Microsoft-certified driver for NICs. Supported devices include both onboard NICs in Microsoft-certified servers and Microsoft-certified PCI-based NICs.

You can attach an SSR212PP-Series iSCSI storage system to Microsoft Windows 2000, Microsoft Windows Server 2003, and Linux servers that use QLogic QLA4010 HBAs and drivers.

You can attach an SSR212PP-Series iSCSI storage system to qualified Linux servers that use the Cisco Linux driver. Supported devices include both onboard and PCIbased NICs.

You can configure SSR212PP-Series iSCSI storage systems with iSNS servers and clients.

You can connect up to four SSR212PP-Series iSCSI storage systems to a single server.

An SSR212PP2i storage system can connect to a maximum of 20 initiators or a maximum of 10 servers (hosts); an SSR212PPi can connect to a maximum of 10 initiators or a maximum of 10 servers.

18

Intel Storage System SSR212PP User Guide

 

Revision 1.0

You can connect up to four iSCSI HBAs or 4 NIC initiators (2 two-port NICs or 4 one-port NICs) in a server to one SSR212PP2i storage system. SSR212PPi systems support connection to 4 iSCSI HBAs 1 two-port NIC, or 2 one-port NICs.

You cannot use both iSCSI HBAs and NICs in a single server.

Separate servers with HBAs and servers with NICs can connect to the same storage system.

Environment and Configurability

A single host cannot attach to an EMC CLARiiON CX-series and an SSR212PPSeries iSCSI storage system at the same time.

For proper traffic routing in an environment that uses physically separated networks, each network must use a unique sub-network address.

This rule applies to both directly-connected configurations and those that use dedicated subnets for the data paths.

When using multiple NICs in a server (host), each card should be on a different subnet. The default Microsoft iSCSI Initiator configuration ignores additional cards on the same subnet, which require use of the Advanced Log On procedure.

The Cisco Linux iSCSI driver does not support multiple NICs/HBAs on the same subnet. Storage systems connected to Linux servers must configure each storage-processor port on a different subnet.

Intel Storage System SSR212PP User Guide

19

Administration Worksheet

The accompanying Administration Worksheet contains the following blanks that you will need to fill in:

Storage system management port

Storage system iSCSI port

Initiator iSCSI port

Storage System Management Ports

The storage system can have two management ports, one per storage processor (SP). Plan the network and security characteristics for each management port and record the data on the accompanying Administration Worksheet. Use the A section to record network information for the management interface. Your network administrator should provide this information.

IP address The static network IP (Internet Protocol) address (for example, 128.222.78.10) for communication with a management port of a storage processor (SP A or SP B). Each SP has one management port. Make sure that your assigned addresses do not conflict with other devices on the corporate network.

Subnet mask The subnet mask for the local area network (LAN) to which the storage system is connected for management, for example, 255.255.255.0.

Gateway The gateway address for the LAN to which the storage system management port is connected.

Username A valid username for logging in to the management interface must start with a letter and may contain 1 to 32 letters and numbers. The name may not contain punctuation, spaces, or special characters. You can use uppercase and lowercase characters. Usernames are case-sensitive. For example, ABrown is a different username from abrown.

Password A password for logging in to the management interface may contain 1 to 32 characters, consisting of uppercase and lowercase letters and SSR212PP-Series numbers. As with the username, passwords are casesensitive. For example, Azure23 differs from azure23. The password is valid only for the username you specified.

Storage System iSCSI Data Ports

Plan the network and security characteristics for each iSCSI data port and record the data in the B section on the Administration Worksheet. Use the DATA port section to record network information for the iSCSI data ports. Your network administrator should provide this information.

IP address

The static network IP address of the storage system port (for example, 128.222.78.10). This is a iSCSI data port on SP A or SP B. Each SP has two iSCSI data ports.

It is recommended to use these standard Internet addresses for private networks between iSCSI data ports and their corresponding network interface cards and/or host bus adapters:

20

Intel Storage System SSR212PP User Guide

 

Revision 1.0

Class A: 10.0.0.0 - 10.255.255.255

Class B: 172.16.0.0 - 172.31.255.255

Class C: 192.168.0.0 - 192.168.255.255

Make sure that your assigned addresses do not conflict with other devices on the corporate network.

Each NIC or HBA in your server requires a unique IP address. In a server with multiple NICs/HBAs attached directly to the storage system, or on a dedicated iSCSI network, the initiator ports must be on separate subnets.

For example, an SSR212PP2i storage system directly attached to network interface cards in one or two servers could assign network identifiers as follows:

Subnet mask

The subnet mask for the LAN subnet to which the iSCSI data port is connected.

Gateway

The default gateway address for the LAN to which the iSCSI data port is connected. If you do not have a gateway, set the field to 0.0.0.0; do not leave the field blank.

Initiator iSCSI Data Ports

An SSR212PPi (single storage processor) storage system supports as many as 10 initiators; an SSR212PP2i (dual storage processor) storage system can support 20 initiators. Record the following initiator information for as many as 20 initiators in the C section on the Administration Worksheet.

Port Name

This field is not mandatory, but you might find it useful to have a self-determined identifier, especially in configurations with multiple iSCSI ports; for example, srvr1NIC3prt0.

IP Address for iSCSI Initiator Port

The network IP (Internet Protocol) address of the initiator port. See the addressing recommendations in "IP address" on page 20.

The initiator port addresses are not the related to the public IP address of the server in which initiator ports reside.

Intel Storage System SSR212PP User Guide

21

Subnet Mask for iSCSI Initiator Port

The subnet mask for the LAN to which the initiator port is connected.

Default Gateway for iSCSI Initiator Port

The default gateway address for the LAN to which the initiator port is connected. This parameter does not apply to a system with a direct connection.

Revision 1.0

Sample SSR212PP2i and SSR212PPi Configurations

The following examples show viable iSCSI configurations in order of increasing complexity. Use them to design your own iSCSI environment. For example, you need to determine whether you want to connect your iSCSI storage system directly to a server, set up a dedicated iSCSI LAN for the storage system and its iSCSI initiators (a recommended, simple configuration) or include the iSCSI storage system in a shared configuration that requires more network expertise and potentially complex Challenge Handshake Authentication Protocol (CHAP) security. (Note that to avoid system downtime, you should set up and enable CHAP before your servers and the iSCSI storage system begin exchanging data.)

This section describes the following sample configurations:

"SSR212PPi Directly Connected to One Server" on page 24

"SSR212PPi Directly Connected to Two Servers" on page 25

Management port IP addresses should match the corporate network scheme.

Advantages

You can easily migrate this low-cost storage for a single server to a switched environment.

The dedicated iSCSI path ensures maximum throughput from the host to the storage system.

The dedicated path provides inherent security.

Disadvantages

Since only one server can connect to the storage system, this configuration does not take full advantage of the SSR212PPi s connectivity capabilities.

While this configuration provides port failover and load balancing, it does not allow SP failover.

Advantages

You can easily migrate this low-cost storage for two servers to a switched environment.

The dedicated iSCSI path ensures maximum throughput from the host to the storage system.

Since two servers can connect to the storage system, this configuration takes advantage of the SSR212PPi s port connectivity capabilities.

The dedicated paths provide inherent security.

Disadvantages

One storage processor does not allow for failover in case of SP failure.

A single path from each server prohibits failover or load balancing.

Management port IP addresses should match the corporate network scheme.

Advantages

You can easily migrate this low-cost storage for a single server to a switched environment.

Redundant paths to the SSR212PP2i provide better failover capabilities. They sustain access to the storage system in the event of an iSCSI initiator, cable, or data port failure.

The dedicated iSCSI path ensures maximum throughput from host to storage system.

Disadvantages

Since only one server can connect to the storage system, this configuration does not take full advantage of the SSR212PP2i s connectivity capabilities.

A single server does not allow for expansion.

Low-cost storage for up to ten servers.

Connection to multiple servers maximizes use of the storage system s capabilities.

Using a dedicated iSCSI LAN avoids network contention with your corporate LAN and reduces security risks.

This configuration provides failover capabilities in the event of a storage processor failure.

Using two storage processors improves overall storage system performance.

Disadvantages

This configuration has limited failover capability since the single initiator and single switch provide only one path from a server to the iSCSI Ethernet switch.
