Connecting SCSI and RAID Adapters
9-2
RAID Configuration Guidelines
•
Fault management must be supported and enabled by the host
adapter for disk drive hot swapping.
•
When adding a RAID host adapter to a server that does not have
RAID installed, use the RAID software to configure your server for
RAID operation.
•
Use narrow SBB disk drives with a narrow RAID host adapter.
•
Select the disk drives in the SBB bays for hot-swap support in a
RAID server.
•
Use the same capacity disk drives in a RAID group, otherwise the
difference in disk drive capacity will be lost.
•
The maximum number of logical disk drives in a RAID group is
eight.
•
To maximize the I/O performance of your multi-channel RAID
subsystem, connect each disk drive in a RAID group on a separate
SCSI channel. This enables the RAID host adapter concurrent
access to all disk drives.
•
Supported RAID levels include: 0, 1, 0+1, 5, and RAID 7 (JBOD).
