IBM Type 7977 manual Using the IBM ServeRAID Configuration Utility program

–View the RAID configuration and associated devices

–Monitor operation of the RAID controller

Consider the following information when you use the IBM ServeRAID Configuration Utility program or ServeRAID Manager to configure and manage arrays:

vThe ServeRAID-8s SAS controller supports RAID levels 0, 1, 1E, 5. 6, 10, 50, and 60.

vServers that come with twelve 2.5-inch hot-swap SAS drives also come with two ServeRAID SAS controllers; a ServeRAID-8k controller in the ServeRAID connector on the system board and a ServeRAID-8s controller in PCI Express slot 2. The ServeRAID-8k controller supports the first eight hard disk drives, and the ServeRAID-8s controller supports the four remaining hard disk drives.

vThe integrated ServeRAID-8k controller is disabled when BIOS detects an optional ServeRAID-10is has been installed in the server.

vWhen you configure the 12 hard disk drives, you may configure the first eight drives into an array that is attached to the ServeRAID-8k and the remaining four drives into an array that is attached to the ServeRAID-8s.

vHard disk drive capacities affect how you create arrays. The drives in an array can have different capacities, but the ServeRAID controllers treat them as if they all have the capacity of the smallest hard disk drive.

vTo help ensure signal quality, do not use drives with different speeds and data rates.

vDo not include SAS and SATA drives in the same array.

vTo update the firmware and BIOS code for an optional ServeRAID controller or controllers, you must use the IBM ServeRAID Support CD that comes with the ServeRAID option.
