RAID Software User’s Guide 1
1 Overview
The software described in this document is designed for use with Intel
®
RAID controllers, and
with on-serverboard RAID solutions that use the Intel
®
RAID Software Stack 3 (driver
package names begin with “ir3”), Embedded Server RAID Technology 2 (driver package
names begin with ESRT2) or Intel
®
IT/IR RAID.
Supported Hardware
This manual covers the software stack that is shared by multiple Intel
®
server products:
• Intel
®
Embedded Server RAID Technology 2 (ESRT2) on the Intel
®
Enterprise South
Bridge 2 (ESB2) in the chipset, the Intel
®
I/O Controller Hub 9R (ICH9R), the Intel
®
3420 PCH chipset, Intel
®
C200 series chipset and Intel
®
C600 series chipset used in the
following:
—Intel
®
Server Board S1200BTL/S1200BTS
—Intel
®
Server Boards based on the Intel
®
S5000 and S7000 chipsets
—Intel
®
Server Boards based on the Intel
®
5500/5520 chipset with the Intel
®
I/O
Controller Hub 10R (ICH10R)
—Intel
®
Server Boards that include the LSI* 1064e SAS (Serially attached SCSI)
controller and some that include the LSI* 1068 SAS controller
—Intel
®
Server Boards S3420GP
—Intel
®
Server Boards S3200SH and X38ML
—Intel
®
SAS Entry RAID Module AXX4SASMOD (when the module is in
ESRTII mode)
—Intel
®
RAID Controller SASMF8I
Intel
®
Embedded Server RAID Technology 2 provides driver based RAID modes 0,1,
and 10 with an optional RAID 5 mode provided by Intel
®
RAID C600 Upgrade Key
RKSATA4R5, RKSATA8R5, RKSAS4R5 or RKSAS8R5.
Intel
®
Embedded Server RAID Technology 2 provides driver-based RAID modes 0, 1,
and 10 with an optional RAID 5 mode provided by the Intel
®
RAID Activation Key
AXXRAKSW5 on the ESB2 and LSI* 1064e on some models of Intel
®
server boards.
ESB2 supports SATA only.
LSI* SAS 1064e and 1068 provide SATA (Serial ATA) and SAS support. Not all 1068
SAS boards provide Intel
®
Embedded Server RAID Technology 2 modes.
Intel
®
Embedded Server RAID Technology 2 must be enabled in the server system BIOS
before it is available. Intel
®
Embedded Server RAID Technology 2 is limited to a
maximum of eight drives including hot spare(s). Expander devices are not yet supported
by ESRT2.
