IBM Advanced SerialRAID/X, Руководство по установке

Страница: 13 / 54

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.
