iv BladeCenter S Types 7779 and 8886: Storage modules

Chapter 1. BladeCenter S Types 7779 and 8886 disk storage

module

Disk storage modules can be installed in storage module bay 1 and storage module

bay 2 of the BladeCenter S chassis.

Disk storage modules

You can install a maximum of two disk storage modules in the BladeCenter S

chassis and each disk storage module contains hot-swap hard disk drives. A disk

storage module and the hard disk drives installed in that disk storage module are

commonly referred to as integrated shared storage because this storage is integrated

in the BladeCenter S chassis and shared among the blade servers in the

BladeCenter S system.

Each disk storage module can support up to twelve hot-swap, 2.5-inch hard disk

drives. Please note that only SAS hard disk drives are supported. Thus, only SAS

RAID controller modules can be used.

Within each disk storage module, the hard disk drives are numbered 1 through 12

from top to bottom for the 2.5-inch hard disk drive configuration.

Note: Each hard disk drive bay must contain either a hard disk drive or a

drive-bay filler.

Note: Four power modules are required in the BladeCenter S chassis if both disk

storage modules are installed.

To access the hard disk drives in the disk storage module, SAS RAID controller

modules must be installed.

Note:

1. SAS RAID controller modules must be installed, one in I/O module bay 3 and

the other in I/O module bay 4. Each SAS RAID controller module will have

access to both disk storage modules (for high availability).

2. Mixing one 2.5-inch disk storage module and one 3.5-inch disk storage module

in a BladeCenter S chassis is currently not supported.

There is one LED on each disk storage module:

Fault Solid (amber) when there is a disk storage module failure.

There are two LEDs on each hard disk drive:

Green Flashing when an operation, such as a read or a write, is being performed.

Flashing when the hard disk drive is being rebuilt (fast blink) or identified

(slow blink).

Note: When power is restored to the BladeCenter S chassis after a

complete loss of power and you have implemented the hard disk drives as

a redundant array (RAID 1, RAID 10, RAID 5), the green light will blink as

the hard disk drive is being resynchronized.

The redundant array is accessible during resynchronization although

performance may be slightly slower.

Amber

Solid when there is a drive failure.

Chapter 2. Installation guidelines

Before you remove or replace a component, read the following information.

vRead Safety and “Handling static-sensitive devices” on page 4. This information

will help you work safely.

vObserve good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

vYou do not have to disconnect the BladeCenter S system from power to install or

replace any of the hot-swap modules. You must shut down the operating system

and turn off a hot-swap blade server before you remove it, but you do not have

to remove power from the BladeCenter S system itself.

vDo not attempt to lift an object that you think is too heavy for you. If you have

to lift a heavy object, observe the following precautions:

– Make sure that you stand safely without slipping.

– Distribute the weight of the object equally between your feet.

– Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing

up with your leg muscles.

vMake sure that you have an adequate number of properly grounded electrical

outlets for the BladeCenter S system.

vBack up all important data before you make changes to disk drives.

vHave a small flat-blade screwdriver available.

vOrange on a component or an orange label on or near a component indicates

that the component may be hot-swapped, which means that you can remove or

install the component while the BladeCenter S system is running. (Orange can

also indicate touch points on hot-swap components.) See the instructions for

removing or installing a specific hot-swap component for any additional

procedures that you might have to perform before you remove or install the

component.

vBlue on a component indicates touch points, where you can grip the component

to remove it from or install it in the BladeCenter S chassis, open or close a latch,

and so on.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure the

following requirements are met.

vEach of the module bays on the front and rear of the BladeCenter S chassis has

either a module or a module bay filler installed in it.

vEach of the blade bays on the front of the BladeCenter S chassis has either a

blade server or a blade bay filler installed in it.

vEach of the disk storage module bays has a disk storage module or disk storage

module filler installed in it. If a disk storage module is installed, each of the

drive bays has a hard disk drive or a hard disk drive bay filler installed in it.

vEach of the drive bays in a blade server storage expansion option has either a

hot-swap drive or a filler panel installed.

vYou have followed the cabling instructions that come with optional adapters.

vCables for the optional modules are routed correctly.

vA failed fan module is replaced as soon as possible.

Handling static-sensitive devices

Make sure that you read these guidelines before handing static-sensitive devices.

Attention: Static electricity can damage the BladeCenter S chassis and other

electronic devices. To avoid damage, keep static-sensitive devices in their

static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following

precautions:

vLimit your movement. Movement can cause static electricity to build up around

you.

vThe use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available.

vHandle the device carefully, holding it by its edges or its frame.

vDo not touch solder joints, pins, or exposed circuitry.

vDo not leave the device where others can handle and damage it.

vWhile the device is still in its static-protective package, touch it to an unpainted

metal part of the BladeCenter S chassis or rack for at least 2 seconds. This drains

static electricity from the package and from your body.

vRemove the device from its package and install it immediately without setting

down the device. If it is necessary to set down the device, put it back into its

static-protective package.

vTake additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.
