Configuring SATA RAID devices

This section describes how to use the Intel® Rapid Storage Manager option ROM Configuration utility
to set up and manage SATA RAID volumes.
The following SATA RAID configurations are supported on this computer:
Up to the computer-specific maximum number of internal SATA hard disk drives and eSATA drives
(if you use an optional eSATA bulkhead cable)
Intel Rapid Storage Manager (IRSM) for Windows
If only a single HDD is attached, the Intel Rapid Storage Manager option ROM does not execute.
Associated messages are not displayed.
The Intel SATA AHCI BIOS executes when you select RAID+AHCI for the SATA emulation mode. This
BIOS is only used to support serial-attached drives configured as a RAID array.
This section does not apply to configuring SATA RAID in the Linux environment. For Linux SATA RAID,
refer to the Software RAID in Linux Workstations section in the HP Workstations for Linux User Guide at
http://www.hp.com/support/linux_user_manual.

Attaching SATA HDDs

Attach the required minimum number of SATA hard drives for the desired RAID level:
RAID 0 – Striped disk array
Two drive minimum
Improved I/O performance
No fault tolerance
RAID 1 — Mirrored disk array
Two drives
100% redundancy
Can recover from single drive failure
Improved read performance
RAID 5 — Striped disk array with distributed parity
Three or more drives (for workstations that support three or more hard drives)
Fault tolerant and provides I/O performance improvement, especially for write-biased
applications
Single drive failure does not cause data loss (performance is compromised until the failed
drive is replaced and the array rebuilt).
