viii IBM Advanced SerialRAID/X Adapter: Installation Guide

Chapter 1. Overview

The IBM Advanced SerialRAID/X Adapter allows you to connect SSA disk drives to certain system units with a Peripheral Component Interconnect (PCI) bus. These disk drives can be accessed individually or they can be configured in RAID arrays. RAID (Redundant Array of Independent Disks) provides a way to spread stored data among a number of hard disk drives attached to a host system. A PCI bus provides high-speed data transfer. A Fast-Write Cache feature further improves the performance of the adapter.

You can create, control, and manage a RAID configuration with supporting host software. The IBM Advanced SerialRAID/X Adapter supports data rates up to 40 MB per second on each SSA interface; and data rates up to 120 MB per second on the PCI bus. You can install up to 6 IBM Advanced SerialRAID/X Adapters in some host systems, depending on the system unit.

Serial Storage Architecture (SSA) is a high-performance serial-interconnect technology used to connect I/O devices and host adapters. SSA is an open standard, and SSA specifications have been approved by the SSA Industry Association and are in the process of being approved as an ANSI standard through the ANSI X3T10.1 subcommittee.

Handling the Adapter

Attention: Static electricity can damage this adapter and your system unit. To avoid

damage, keep your adapter in its protective bag until you are ready to install. To reduce the possibility of electrostatic discharge, follow the precautions listed below.

Electrostatic Discharge Protection

To prevent electrostatic discharge: v Always wear an electrostatic discharge (ESD) wrist strap correctly connected to an

ESD ground bracket when you handle the adapter. This prevents possible damage to the adapter and decreases any possible impact to system operations.

v Limit your movement. Movement can cause static electricity to build up around you. v Handle the adapter carefully and by the edges. v Do not touch any exposed printed circuitry. v Prevent other people from touching the components or the adapter card. v When you are installing the adapter, touch the static-protective package containing

the adapter to a metal expansion-slot screw or other unpainted metal surface on the computer, for at least 2 seconds. (This drains static electricity from the package and from your body.)

v When possible, remove the adapter and install it directly into the computer without

setting it down. If this is not possible, place the adapter, component side up, on the static-protective bag on a flat surface until the adapter is installed.

v Do not place the adapter on the computer cover or on a metal table.

SSA Connectors

The IBM Advanced SerialRAID/X Adapter has four external connectors, arranged in two pairs. Up to 48 SSA disk drives can be connected in a loop between each pair of external connectors. If you are not using RAID-0 arrays you can connect up to two IBM Advanced SerialRAID/X Adapters in the SSA loop.

“Appendix A. Connecting SSA Devices to the Adapter” on page 31 provides more information about SSA loops. Figure 1 shows the card.

Adapter Card Lights

On the IBM Advanced SerialRAID/X Adapter card, there is a light next to the pair of SSA connectors (port 1 and port 2) for each SSA loop. v The light is on continuously when power is turned on to the adapter and both ports

for that loop are operational; that is, the devices connected next to the adapter in the loop have power turned on to them, are connected correctly to the adapter, and are operational.

v The light flashes continuously if one of the ports is not operational. That occurs when

the cable to that port is not connected correctly or the device connected next to the adapter in the loop is not operational.

v The light is off if both ports are not operational.

Summary of Installation Procedures

Installing the adapter consists of the following steps:

v Taking an inventory of all pieces necessary for installation v Installing the adapter v Connecting the SSA disk drives v Installing the SSA device drivers, software, and any required microcode.

4 IBM Advanced SerialRAID/X Adapter: Installation Guide

Chapter 2. Preparing for Installation

This section shows you the items you need to install the IBM Advanced SerialRAID/X Adapter. It also describes the cable requirements.

Inventory

To install the IBM Advanced SerialRAID/X Adapter, you need:

v The adapter. v The diskettes that are supplied with the adapter. v The CD-ROM that is supplied with the adapter contains the device-driver software,

the event logger, the Remote Systems Management (RSM), the SSA-disk-drive microcode, the SSA-adapter microcode, and the product manuals in Adobe Acrobat PDF format.

v Your system unit documentation. v Your operating system documentation. v A flat-blade screwdriver. v An electrostatic discharge (ESD) kit.

To connect SSA disk drives to the IBM Advanced SerialRAID/X Adapter, you need:

v External SSA cables. v SSA Screwdriver Part Number 32H7059. v Fibre-Optic Extenders, if you are using fibre optic cables. (The extenders are

supplied in pairs as a feature of the unit in which the SSA disk drives are installed, for example, the 7133 disk system.)

v The plan for your SSA subsystem configuration. v The documentation for the unit in which the SSA disk drives are installed.

Determining Your Cable Requirements

There are two types of SSA cable: v Copper cables with conventional connectors at each end. These enable you to

connect SSA nodes at distances up to 25 m (82 feet).

v Fibre-optic cables. These enable you to connect two SSA nodes at distances up to

10 km (32800 feet) in single-mode operation. These require the use of Fibre-Optic Extenders; these are supplied in pairs as a feature of the unit in which the SSA disk drives are installed, for example, the 7133 disk system.

The number and type of cables that you need and their lengths should have been decided at the time that your SSA subsystem was ordered. If the configuration plan that was created then is not available to you, use the sample configuration information that is provided in the documentation for the unit in which the SSA disk drives are installed. “Appendix A. Connecting SSA Devices to the Adapter” on page 31 provides some general information about SSA configurations.

This section describes how to install the device driver. You must have either downloaded an updated Windows NT device driver from the SSA World Wide Web Support page, or have the diskette labeled Windows NT Device Drivers that is provided with your adapter.

The following steps describe how to install the device driver:

1. Select Start, select Settings, select Control Panel, double click on SCSI Adapters.

2. Select the Drivers tab, and click Add

3. When prompted, click Have Disk and insert the Windows NT device drivers diskette.

Note: Windows NT Server 4.0 may ask you for the path a second time. Enter a:\

again.

4. Select IBM Advanced SerialRAID/X Adapter from the list that appears even if you have any other SSA adapters installed in the machine.

5. When finished you will be prompted to restart your computer. Click OK

6. When the system unit restarts, install the host software as described below.

Installing the Host Software

Note: It is assumed you have Windows NT Server 4.0 installed and running on the

your system unit, that you have already installed the IBM Advanced SerialRAID/X Adapter in the system unit and have installed the appropriate device driver. Windows NT Networking must also be installed, including the TCP/IP protocol if installing the stand-alone version of RSM.

1. Insert the CD-ROM provided. Go to Start and select Run. Enter the following

<cd>:\nt\setup.exe

Where <cd> is your CD-ROM drive letter.

2. The setup program will proceed as follows: a. Look for the device driver on the system and exit if not found. b. Select the type of installation, either Automatic or Custom. If installing for the

first time, you should select Custom. c. Look for existing software components. d. Inform you of what needs to be updated and what is at the latest level. You can

choose to install any component even if you have the latest level, or wish to

downgrade. e. Update the host software as necessary. f. Launch Adobe Acrobat Reader Setup (if required).

Note: Setup must stop running services before updating the program files; you will

be prompted if setup needs to stop a service. If the subsequent file copy fails, the service may have failed to stop. Follow the instructions in “Checking the SSA Services Status” on page 17, but click Stop instead of Start and re-run setup.

3. When setup completes, it will open a text document which describes how to get further help, access the SSA Tools Menu, and describes what else the CD-ROM contains. You should take the time to read the readme files contained in the \docs\readme directory on the CD-ROM. They are also available in HTML format via the SSA Tools Menu.

Relevant microcode is also supplied on the CD-ROM in the \ucode directory. This microcode was correct at the date of manufacture and you should check the SSA World Wide Web Support page when you have finished installing the host software. See “Chapter 5. Downloading the Latest Microcode” on page 27 for details.

You should now verify that the installation of the software has been completed successfully. “Verifying the Installation” on page 16 describe this process.

Installing NT onto an SSA Resource in a New Server

There are four main steps involved:

1. Upgrade the firmware on the IBM Advanced SerialRAID/X Adapter and create an SSA resource using the DOS configurator.

2. Install Windows NT, introducing an updated version of the Hardware Abstraction Layer (HAL) during the normal install procedure.

3. Install Service Pack 5 (this is the minimum level of NT Service Pack required to operate the IBM Advanced SerialRAID/X Adapter).

4. If the Intel Server is a multiprocessor machine, then upgrade the installed software to the multiprocessor version.

Notes:

1. If you have an existing installation with Windows NT Server (at Service Pack 4) on a RAID 5 array attached to an IBM SSA RAID adapter (32H3811), then this can be transferred to an IBM Advanced SerialRAID/X Adapter (provided it meets the configuration rules for the IBM Advanced SerialRAID/X Adapter). However this must only be performed after the adapter firmware upgrade (step 1) has taken place.

2. We do not recommend the use of RAID-5 for the NT system disk for performance reasons.

Before starting

Copy the updated Uniprocessor HAL (hal.dll) for your computer obtained from the Microsoft Windows NT Service Pack 5 CD to a blank diskette. Add the files txtsetup.oem, and halapic.tag provided in the \ntboot directory within the SSA driver package. If your server uses a different uniprocessor HAL DLL to ″halapic.dll″ then also edit txtsetup.oem, and change the line which begins: ″hal = d1, ...″ to point to the HAL file your computer uses.

Note: Even if your computer is a multiprocessor server you must use the uniprocessor

HAL for installation, and then follow step 4 to upgrade to a multiprocessor HAL.

Detach or disable any SCSI, IDE, or other non-SSA devices in the Server (other than the CD-ROM and diskette drive). Install the IBM Advanced SerialRAID/X adapter into

Chapter 4. Installing the Device Driver Software and Microcode 13

one of the PCI slots. If your machine hardware manual describes PCI slot priority, then this adapter should be in a higher priority slot than any other storage device which may be installed later.

Attach the SSA drives to the adapter, and power them on.

Upgrading the firmware

Upgrade the firmware on the IBM Advanced SerialRAID/X Adapter:

1. The latest level of firmware for all IBM SSA Adapters is available from the SSA World Wide Web Support page at:

http://www.hursley.ibm.com/ssa/

The level required is 6300 or later. The firmware should be installed under DOS, instructions for doing this are contained in the README.NOW file contained in the firmware download package for DOS.

2. Insert the bootable DOS firmware upgrade diskette in the server and power on. During the power on sequence the IBM Advanced SerialRAID/X Adapter will display a banner. If this states that the CBIOS is disabled, enable the CBIOS by pressing the Tab key.

3. Configure the SSA disks attached to the IBM Advanced SerialRAID/X Adapter using

ISSACFG. Instructions for using the configurator can be found in the IBM Advanced SerialRAID/X Adapter: User’s Guide and Maintenance Information.

You should only create one resource at this time, that is the resource that you want to install Windows NT on.

When the resource on which NT is to be installed is attached as a System Resource, ensure the Resource ID given to it is 1. If the resource is in a cluster environment, the disk or array must be made private to this server.

4. Reboot the Server using a DOS boot diskette. During the power up process, the IBM Advanced SerialRAID/X Adapter will display the line ″Attached devices...″. The number displayed at the end of the line should be ″80″ hexadecimal, this indicates the boot hard disk. If it is not, then re-run ISSACFG to correct the disk configuration.

Install windows NT

Install Windows NT, introducing an updated version of the HAL during the normal install procedure.

1. Before NT can be installed, a boot partition must be created on the SSA disks using DOS. We recommend creating a 1GB partition using FDISK. Make this the active partition, reboot, and then FORMAT the partition under DOS.

2. Install the NT Server V4.0 setup diskette 1, and reboot the Server.

3. Shortly after displaying the IBM Advanced SerialRAID/X Adapter banner the text: ″Setup is inspecting your computer’s hardware configuration″ will appear. You must press F5 as soon as this appears.

4. Soon after this you will be prompted with the message:

Windows NT Setup Setup could not determine the type of computer you have, or you have chosen to manually specify the computer type. Select the computer type from the following list, or select "Other" if you have a device support disk provided by your computer manufacturer.

Select ″Other″ and when prompted insert the diskette containing the updated Uniprocessor HAL for your computer.

5. When this has been read proceed with the installation. You will be asked if you wish to install any storage devices. Press ″s″ twice, and when asked to insert the Manufacturer’s OEM diskette, place the latest SSA driver/installation diskette in the drive (the latest version is available from the SSA World Wide Web site).

6. After returning to the ″search for devices″ panel, press ″s″ again, scroll up, and select the appropriate CD-ROM driver for your server.

7. Proceed with the installation, and install NT on the 1GB partition created earlier. It may be that NT will not accept the partition created under DOS, in which case, delete and create the partition within the NT install process. We recommend that you format with FAT.

8. Proceed with the installation. At the point where networking is installed, we recommend you select:

Do not connect this computer to a network at this time.

and complete network installation after Service Pack 5 has been installed. See “Network Installation” on page 16. You will have to re-apply SP5 after you have set networking up.

9. Complete the installation of NT Server V4.0 as described in “Installing the Host Software” on page 12.

Install Service Pack 5

Install Service Pack 5 on the Server. (This is the minimum level of NT Service Pack required to operate the IBM Advanced SerialRAID/X adapter).

Upgrading a multiprocessor version

If the Intel Server is a multiprocessor machine, then upgrade the installed software to the multiprocessor version.

1. If your machine has more than one Intel processor installed, then the HAL and associated code needs to be upgraded to the multiprocessor version.

2. Before following this procedure we recommend that you should read articles:

Q156358

How to manually add support for a second processor

Q197896

Uptomp.exe requires access to the Txtsetup.sif file

from the Microsoft support Web site.

Chapter 4. Installing the Device Driver Software and Microcode 15

| | | | | |

| |

| | | |

| |

| | | |

| |

| | |

| |

3. The Uptomp.exe code is provided by Microsoft on their Windows NT Resource Kit (in the directory i386\config). If you do not have access to this then you will have to follow the process described in article Q156358. Otherwise follow the steps below.

4. Create a temporary directory on the NT boot partition, and copy into it all the files from the \i386 directory of the Service Pack 5 CD.

5. Create another temporary directory and copy all the uptomp*.* files from the Resource Kit.

6. Copy the file Txtsetup.sif into both of these directories from the \i386 directory of the NT Installation CD.

7. Run uptomp.exe, and where it prompts for a directory containing the HAL, point to the directory created in 4. Select the correct Multiprocessor HAL for your Server (for instance, on IBM Netfinity Servers it is MPS Multiprocessor PC).

8. At the point where the process prompts to install NT files, again point to the directory created in 4 above.

Network Installation

When networking is not installed until after SP5 has been applied, and the server is eventually added to an NT domain, the Domain Admins global group is not automatically added to the local administrators’ group. This means that if a domain administrator tries to log on to the server, they will get a message that says:

The local policy of this system does not permit you to log on interactively.

This can be easily remedied by logging on as the local administrator and adding the global Domain Admins group to the local Administrators group.

Verifying the Installation

When the adapter, the device drivers, and the host software, have been installed you can verify everything has completed successfully as described below.

If you encounter any problems during installation or after you install, refer to:

1. The IBM Advanced SerialRAID/X Adapter: User’s Guide and Maintenance Information Manual contained in the \docs directory on the CD-ROM.

Chapter 5. Downloading the Latest Microcode

Attention: Do not download code to drives that are in use. Ensure that no I/O

operations are in progress to the disk drive and that any disk drive that is a download target is not being used by any other system.

Since I/O operations may be performed by a RAID adapter without any host system involvement, for example, when rebuilding an array, you must also avoid downloading to disk drives that are members of an array that is in the rebuilding state.

Downloading the Microcode

Notes:

1. All microcode updates may be performed under Windows NT, but we recommend that, if possible, you restart your system unit from the PC-DOS bootable diskettes that are available from the SSA World Wide Web Support page at:

http://www.hursley.ibm.com/ssa/

2. For Novell NetWare, microcode updates must be performed from PC-DOS.

3. Adapter microcode may be also referred to as firmware.

The SSA World Wide Web Support page contains the latest levels of all SSA adapter, drive and enclosure microcode. The URL below is for the microcode page; you should visit it and get the latest packages. The microcode files and download tools it copies to your hard drive (usually to c:\issa\update for Windows NT) should be used in preference to those on the CD-ROM.

http://www.hursley.ibm.com/ssa/pcserver/

To download from DOS we recommend you download the relevant diskette image from the SSA World Wide Web Support page. Follow the instructions provided in the readme file. The relevant microcode is supplied on the CD-ROM in the \ucode directory. This microcode was correct at the date of manufacture but you should check the SSA World Wide Web Support page for the latest levels. Usage information for the DOS download utilities can be found in the DOS readme (DOSRME.TXT).

The instructions below describe how to download under Windows NT.

Downloading Adapter Microcode

1. Ensure that no I/O is being performed by the adapter you wish to download to.

2. Copy the new adapter microcode image to the same directory as the download tool where you installed the host software (usually c:\issa).

If you have downloaded a microcode update from the website above, the latest download utility and microcode will have been extracted to c:\issa\update\ssaflash.

| | |

| |

Note: Adapter microcode images are called:

ADAPxxxx.Lyy

where xxxx is the microcode level and yy is the ″Loadable Microcode Level″ (LL) in the adapter VPD (Vital Product Data).

For the IBM Advanced SerialRAID/X Adapter, the LL = 05.

3. Run the following command from a command prompt, after changing drive and directory to where you copied the microcode image :

issaadld ADAPxxxx.L05

4. The downloader will only download the microcode image to adapters with the appropriate LL type. That is, an adapter of type LL05 can only have microcode images of type LL05 downloaded to it. If the downloader finds another LL type, such as 04, it will ignore it and an appropriate ″skipping adapter with LLxx″ message is displayed.

Run issaadld.exe with no command line parameters to view full usage instructions, or for Windows NT, click on the SSA Tools Help link on the SSA Tools menu.

Optionally you can specify to only download to one adapter. You require the node number for this adapter which is available on the Adapter List page of RSM for Windows NT or by using ISSACFG for both NT and NetWare.

Attention: Care should be taken not to change the file extension on microcode files as damage may be caused to adapters if the wrong image file is applied.

5. When you are returned to the command prompt, you have completed updating the adapter microcode and all modified adapters will have been automatically reset.

Downloading Disk Microcode

1. Ensure that no I/O is being performed to any of the target disk drives.

2. Ensure you have fully read, understood and complied with the warning notes at the start of this chapter.

3. Copy the new drive microcode image (or images) to the same directory as the download tool to the same directory as the host software (usually c:\issa).

If you have downloaded a microcode update from the website above, the latest download utility and microcode will have been extracted to c:\issa\update\ssaflash.

Note: Drive microcode images are called: xxxxyyyy.dl

where xxxx is the drive type, one of DFHC, DCHC, DGHC, DRHC, DRVC, or WAAH; and yyyy is the microcode level (from the disk VPD level fields)

4. Run the following command from an NT Command Prompt, after changing drive and directory to where you copied the microcode image:

issaddld xxxxyyyy.dl

Note: You may required to download more than one type of drive microcode to

update all drives. We recommend you apply all types of drive microcode to determine which type of drives you have.

28 IBM Advanced SerialRAID/X Adapter: Installation Guide

5. The downloader will only download the microcode image to drives of the appropriate type. For example, a drive of type DCHC can only have microcode images of type DCHC downloaded to it. If the downloader finds another drive type such as DFHC it will ignore the drive and an appropriate ″skipping drive of type xxxx″ message is displayed. Optionally you can specify to only download to one disk. You require the SSA UID for this disk which is available on the appropriate Disk View page of RSM or ISSACFG (in Disk service Aids).

Attention: Care should be taken not to change the file names of microcode files as damage may be caused to drives if the wrong image file is applied.

6. When you are returned to the command prompt, downloading of this drive type has completed. Repeat for all download types, DFHC, DCHC, DGHC, DRHC, DRVC, and WAAH.

Notes:

a. The downloader skips drives that are at the current level. b. If a download image does not get used, in other words the downloader skips all

drives, you do not need to apply this download type in the future unless you add new drives to your system.

c. You will need to use the same download types when later levels are released.

7. When all appropriate drive types have been updated you have completed downloading the disk microcode and all modified drives will have been automatically reset.

Enclosure Controller Microcode (7133 Models D40 and T40)

Certain models of SSA drive enclosures, those with SCSI Enclosure Services (SES) controllers, can be updated with new microcode.

1. Ensure that no I/O is being performed by any of the drives in the enclosure you wish to download to.

2. Copy the new enclosure microcode image to the same directory as the download tool, usually c:\issa.

If you have downloaded a microcode update from the website above, the latest download utility and microcode will have been extracted to c:\issa\update\ssaflash.

Note: Enclosure microcode images are called mcodexxx.hex where xxx is the

controller code level.

3. Run the following command from an NT Command Prompt after changing drive and directory to the location where you copied the microcode image to:

issaedld mcodexxx.hex

4. The downloader will only download the microcode image to enclosures containing the appropriate controller.

5. When you are returned to the command prompt, you have updated all enclosure controller microcode and all modified controllers will have been automatically reset.

Checking the Existing Levels of Microcode and Host Software

You can check the microcode and software levels by using ISSACFG for NetWare or by using the RSM for Windows NT, Netware 4.2, and Netware 5.

RSM provides an online level check function that allows you to check the level of your adapter microcode over an internet connection. Simply click any of the check levels links within RSM on an internet connected browser.

RSM provides level checking for :

v The device drivers v The event logger v The RSM configurator itself v All adapter, drive, and enclosure microcode

To find out what level of software, device driver, or microcode you are using: v View the device driver version (on the RSM Adapter List page, above the list of

adapters).

v View the Event Logger version (on the RSM Event Logger page). v View the RSM Configurator version (in the browser title bar) v Determine the adapter type and microcode level (on the Adapter View pages, the

Appendix A. Connecting SSA Devices to the Adapter

SSA devices can be connected to the adapter and to each other in many ways. Sample configurations are given in the documentation for the units (for example, the 7133) in which SSA devices can be installed. Marketing representatives have additional information on configuring for performance and availability.

The configuration must be planned at the time that the SSA subsystem is ordered. This must be done so that the correct cables are ordered. This plan should be made available to whoever installs the adapter and the devices.

This section provides general information on SSA configurations.

SSA Loops and Links

In the simplest SSA configuration, SSA devices are connected through two or more links to an SSA adapter that is located in a using system. The devices, SSA links, and SSA adapter are configured in loops. Each loop provides a data path that starts at one connector of the SSA adapter and passes through a link (SSA cable) to the devices. The loop continues through the devices, then returns through another link to a second connector on the SSA adapter.

The maximum permitted length for an external copper cable that connects two SSA nodes (for example, disk drives) is 25 meters (82 feet).

The maximum permitted length for an external fiber optic cable that connects two SSA nodes (for example, disk drives) is 10 kilometers (32808 feet).

Details of the rules for configuring SSA loops are given for this SSA adapter in “Rules for SSA Loops” on page 34.

Loops and Data Paths

All devices that are attached to an SSA adapter, 1 in Figure 2 on page 32, are connected through SSA links 2. The SSA links are configured as loops. Data and commands to a particular device pass through all other devices on the link between the adapter and the target device.

Data can travel in either direction round a loop. The adapter can, therefore, get access to the devices 3 (disk drives in this example) through two data paths. The using system cannot detect which data path is being used.

If a disk drive fails, or is turned off, the loop is broken, and one of the data paths to a particular disk drive is no longer available. The disk drives on the remainder of the loop continue to work, but an error is reported to the system.

In Figure 3 on page 33, disk drive number 3 has failed. Disk drives 1 and 2 can communicate with the using system only through connector A1 of the SSA adapter. Disk drives 4 through 8 can communicate only through connector A2 of the SSA adapter.

Figure 2. SSA Loop

32 IBM Advanced SerialRAID/X Adapter: Installation Guide

If two or more disk drives are turned off, fail, or are removed from the loop, some disk drives might become isolated from the SSA adapter

In Figure 4 on page 34, disk drives 3 and 7 have been removed. Disk drives 1 and 2 can communicate with the system only through connector A1 of the SSA adapter. Disk drive number 8 can communicate with the system only through connector A2 of the SSA adapter. Disk drives 4, 5, and 6 are isolated from the SSA adapter.

Appendix A. Connecting SSA Devices to the Adapter 33

Rules for SSA Loops

For SSA loops that include the IBM Advanced SerialRAID/X Adapter, the following rules apply:

v Each SSA loop must be connected to a valid pair of connectors on the SSA adapter

(that is, either connectors A1 and A2, or connectors B1 and B2).

v A maximum of 48 disk drives can be connected in a particular SSA loop. v If you are not using RAID-0 arrays, a second pair of adapter connectors can be

connected in a particular SSA loop. The second adapter must be another IBM Advanced SerialRAID/X Adapter. If an adapter is connected in two SSA loops and each loop contains a second adapter, the same two adapters must be in both loops, as shown in Figure 5 on page 35.

Subsystem Performance Recommendations

The physical relationship between the disk drives and the adapters in an SSA loop can affect the performance of the subsystem. The guidance below helps you to get best performance from your subsystem.

The following sequence enables you to determine the best relationship between the disk drives and the adapter on an SSA loop that contains a IBM Advanced SerialRAID/X Adapter.

1. Determine which data is accessed most frequently.

2. Assign that data to those disks drives that are farthest (round the loop) from the adapter connectors. By doing this, you prevent the activity of the busiest disk drive from obstructing the data path to the other disk drives.

For example, if a loop contains 16 disk drives, and the adapter connectors are between disk drives 1 and 16, the most-frequently-accessed data should be on disk drives 8 or 9 as shown in Figure 6.
