Dear all,
I need advice which RAID Levels (RAID0, RAID5, non-RAID) one should use for
best performance/availability:
- TSM DB Volumes
- TSM Log Volumes
- TSM Diskpool Volumes
As far my knowledge goes about TSM I know that I should place the DB on one
disk and the log on another disk with TSM mirroring or hardware RAID1. This
is common practice for all DB's.
I am pretty unsure about the diskpool volumes. Will the client sessions
generate large sequential writes (non-RAID) OR will there be random writes
in place (RAID0).
Hardware: IBM RS/6000 with SSA disks.
Any help appreciated!
