Configuring a RAID array
Use this information to configure a RAID array.
Configuring a RAID array applies only to a blade server in which two or more
storage drives are installed.
Note: When configuring a RAID array, the storage drives must use the same type
of interface. For example, a RAID array can be configured with two SAS storage
drives, two SATA storage drives, or two SSD storage drives.
You can use two storage drives in the blade server to implement and manage
RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that
are listed on the ServerProven list at http://www.ibm.com/systems/info/
x86servers/serverproven/compat/us/.
Refer to the Human Interface Infrastructure Configuration Application User Guide in
http://www.ibm.com/support/docview.wss?uid=psg2MIGR-5088601 for more
information on the storage drives and SAS controller configuration.
If an optional RAID expansion card is installed, you can use it to control all of the
storage drives that are installed in the blade server. See the documentation that
comes with the expansion card for information on how to configure the RAID
array.
Important: You must create the RAID array before you install the operating system
on the blade server.
