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.

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.

Spare 11

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, 250- and 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,

PRELIMINARY

and select a disk to be a Hot Spare. Record this information in the Storage System disk information worksheet.

Intel Storage System SSR212PP User Guide 7

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

Disks 4-11

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 starting with 1. However, you can substitute a more meaningful name, such as

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.

217 Gbytes per disk 458 Gbytes per disk

230 Gbytes per disk 445 Gbytes per disk

Virtual Disk n, where n is the sequential number,

Users or

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.

PRELIMINARY

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

PRELIMINARY

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.

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 QLogic SANsurfer

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.

1 login per server to each SP data port

1 login per HBA to each SP data port

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

PRELIMINARY

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 SSR212PP-

Series 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.

Administration W orksheet

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

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, valid only for the username you specified.

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:

Port IP address Subnet mask Gateway

Storage Processor A

iSCSI port

iSCSI NIC/HBA 1

Storage Processor B

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.)

What is Microsoft iSNS?

Microsoft Internet Storage Naming Service (iSNS) is an option that applies to configurations with multiple hosts.

The iSNS service provides automated discovery, management and configuration of iSCSI devices. It eliminates the need to manually configure each individual storage device with its own list of initiators and targets. Once configured, the iSNS server assumes responsibility for the discovery and management of iSCSI devices.

The iSNS service includes an iSNS server component and iSNS client components. The iSNS server must reside somewhere within the IP storage network, for example, in the switch firmware, or on a host. An iSNS client resides on both the SSR212PP-Series iSCSI storage system and any iSCSI hosts connected to the storage system. When you start the storage system, the iSNS client on the storage system gathers all the storage system s iSCSI port information and stores it locally on the storage system. When you add a server to the storage system s iSNS configuration, Navisphere Express establishes a connection from the storage system to the iSNS server, and then registers all the stored information on the storage system with the iSNS server.

To use the features of the iSNS service in an iSCSI storage environment:

 An iSNS server must be running on a network to which the storage system has access.

 The NIC or iSCSI HBA initiators must be able to use the iSNS service.

 The iSNS server must be able to communicate with the storage system.

Figure 19 represents a sample iSNS configuration. In this configuration, the management

and storage networks are separate. The management station is used to configure both the iSNS servers and the storage system (using Navisphere Express). The iSNS servers are also connected to the storage network so that the clients may query them for target information. The storage system uses either the storage or the management network to register its targets (ports) with the iSNS servers.

What is CHAP?

Challenge Handshake Authentication Protocol (CHAP) is an optional iSCSI authentication method where the target authenticates iSCSI initiators. CHAP consists of initiator CHAP and mutual CHAP, depending on which way the authentication occurs. For initiator CHAP, the target authenticates the initiator. Mutual CHAP can be configured in addition to initiator CHAP. For mutual CHAP, the initiator authenticates the target.

Initiator CHAP

To establish a connection and gain access to storage in an initiator CHAP configuration, the initiator must present a username and secret to the iSCSI target. The storage system compares the username and secret with a database of CHAP user accounts to authenticate the initiator.

To set up initiator CHAP authentication, you enter the username and secret on the target, then configure each initiator to use that username and secret.

Mutual CHAP

In a mutual CHAP configuration, both the target and the initiator authenticate each other. In addition to setting up initiator CHAP, you can configure the initiator with a username and secret that the target must present to establish a connection. You must also configure the target to present this username and secret to initiators.

If you are planning to set up optional CHAP authentication security on the storage system, prepare the following storage system CHAP security worksheets for initiator CHAP and mutual CHAP.

PRELIMINARY

46 Intel Storage System SSR212PP User Guide

Revision 1.0

iSCSI CHAP Authentication Worksheets

If the storage system is on a private LAN, you can elect not to configure CHAP authentication. If the storage system is on a public LAN, we strongly recommend that you set CHAP security. If you do not set CHAP security for the storage system, any host connected to the LAN can read from and write to the storage system.

CAUTION

Whenever you record any security information such as the CHAP usernames and secrets (passwords), it is imperative that you store the data in a secure location.

Storage System CHAP Levels

To set up a basic CHAP level, you can add one or more usernames and corresponding

secrets. Any initiator configured with one of these usernames/secrets can establish a connection.

To set up an CHAP. You can create initiator CHAP so that all initiators can use each username/secret (as in basic CHAP). You can also use the iSCSI node name (IQN) to create usernames/secrets that are restricted for use by a single initiator. Optionally, you can configure mutual CHAP with a single target CHAP username/secret.

Initiator CHAP Worksheet

If you want the storage system to authenticate initiators, fill out the Initiator CHAP Worksheet for all initiator accounts. Initiator CHAP must be set up and enabled for iSCSI security to work. The easiest way to configure initiator CHAP is to create a friendly username and secret for all initiators.

Initiator name: ___________________________________________________________ Use initiator name as system CHAP username: Yes___ No___ Allow any initiator to log In with this username and secret: Yes___ No___ CHAP username: _________________________________________________________ CHAP secret: ________________________________ Speciﬁed in hex: Yes___ No___

Handling Field-Replaceable

This section describes the precautions that you must take and the general procedures you must follow when removing, installing, and storing disk modules, fans, memory cards, battery-backed cache cards, the storage processor assembly, or any other field replaceable unit (FRU).

Power issues and FRUs

SSR212PP-Series storage systems are designed to be powered up continually. Disks and power supplies are hot repairable; that is, you can replace faulty units while the system is running. Front bezels should always be attached and each compartment should contain a FRU or filler panel to ensure EMI compliance and proper air flow over the FRUs.

You should not remove a faulty FRU until you have a replacement available.

When you replace or install FRUs, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage. Follow the procedures below to prevent damage to the equipment.

Units (FRU)

Read and understand the following instructions:

 Provide enough room to work on the equipment. Clear the work site of any

unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.

 Do not remove replacement or upgrade FRUs from their antistatic packaging until you

are ready to install them.

 Before you service a storage system, gather together the ESD kit and all other

materials you will need. Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.

 An ESD wristband is supplied with your storage system. To use it, attach the clip of

the ESD wristband (strap) to any bare (unpainted) metal on the storage system; then put the wristband around your wrist with the metal button against your skin.

 Use the ESD kit when handling any FRU. If an ESD kit is not available, follow the

PRELIMINARY

procedures in the "Without an ESD Kit" section.

Intel Storage System SSR212PP User Guide 59

Without an ESD Kit

When an ESD kit is not available, use the following procedures to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

These procedures are not a substitute for the use of an ESD kit. Follow them only when an ESD kit is not available.

 Before touching any FRU, touch a bare (unpainted) metal surface of the cabinet or

storage system.

 Before removing any FRU from its antistatic bag, place one hand firmly on a bare

metal surface of the storage system, and at the same time, pick up the FRU while it is still sealed in the antistatic bag. Once you have done this, do not move around the room or touch other furnishings, personnel, or surfaces until you have installed the FRU.

 When you remove a FRU from the antistatic bag, avoid touching any electronic

components and circuits on it.

 If you must move around the room or touch other surfaces before installing a FRU,

first place the FRU back in the antistatic bag. When you are ready again to install the FRU, repeat these procedures.
