Configuring a RAID array - IBM Flex System x240 Compute Node Types 7863, 8737, 8738, and 8956

Use this information to configure a RAID array.

About this task

Configuring a RAID array applies only to a compute node in which two or more hard disk drives are installed.

Note: When you configure a RAID array, the hard disk drives must use the same type of interface and must have identical capacity and speed.

You can use two hard disk drives in the compute node 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 the IBM ServerProven website. For the compute node, you must configure the RAID by using the LSI Configuration Utility program.

If an optional RAID expansion adapter is installed, you can use it to control all of the hard disk drives that are installed in the compute node. See the documentation that comes with the expansion adapter for information about how to configure the RAID array.

Important: You must create the RAID array before you install the operating system on the compute node.

You can use the LSI Logic Configuration Utility program to configure the hard disk drives and the SAS controller. To start the LSI Logic Configuration Utility, see Using the LSI Logic Configuration Utility.
