v Use ServeRAID Manager to:
– Configure arrays
– View the RAID configuration and associated devices
– Monitor operation of the RAID controllers
Consider the following information when using the IBM ServeRAID Configuration
Utility program and ServeRAID Manager to configure and manage arrays:
v The ServeRAID-8k-l SAS controller that comes with the server supports only
RAID level-0, level-1, and level-10. You can replace it with a ServeRAID-8k SAS
controller that supports additional RAID levels.
v Hard disk drive capacities affect how you create arrays. The drives in an array
can have different capacities, but the ServeRAID controller treats them as if they
all have the capacity of the smallest hard disk drive.
v To help ensure signal quality, do not use drives with different speeds and data
rates.
v To update the firmware and BIOS code for an optional ServeRAID SAS
controller, you must use the IBM ServeRAID Support CD that comes with the
ServeRAID option.
