About the Xserve G5 PCI

Hardware RAID Card

The Xserve G5 PCI Hardware RAID Card offers enhanced

reliability and performance for data transfer and storage

on your Xserve G5 server.

Key features of the PCI Hardware RAID Card and its management software include:

•

Data transfer of up to 150 MB per second per channel

•

Support for RAID levels 0, 1, and 5

•

Ports for three internal SATA drives

•

A built-in hardware engine for RAID parity

•

64 MB of error-correcting (ECC) RAID cache

•

Battery backup for the RAID cache (battery cable must be connected on the card)

•

Hardware support for hot swapping, automatic hot sparing, and drive rebuilding

To install your new RAID card in an Xserve G5, you must install it in a PCI slot, bypassing

the main logic board SATA controllers to allow the RAID card to control the three built-

in drive bays. When configuring the RAID card for the first time, you must reformat the

drives to create at least one RAID volume and then reinstall Mac OS X Server software.

Note:

By bypassing the SATA controllers, your PCI Hardware RAID Card will not support

FireWire Target Disk Mode.

The PCI Hardware RAID Card requires Mac OS X Server version 10.3.5 or later. The card

also requires that the Xserve G5 have BootROM version 5.1.7f0 or later. You can

determine your system’s BootROM version by opening System Profiler (in the Utilities

folder) or by running the command-line utility system_profiler.

Warning:

When you install the PCI Hardware RAID Card, you must completely

reformat your Xserve G5 internal drives and reinstall the Mac OS X Server software. Be

sure to back up any data and system configuration information on your Xserve G5

before proceeding with the card installation.
