Hi TSMers!
I'd like to know what you prefer for protecting the DB since I'm planning in
upgrading the system I can think about the following options:
1 - Main DB files on RAID 1, mirror on RAID 0 and
MirrorWriteDB=Parallel
2 - DB on RAID 1 and no mirror
3 - Main DB files on RAID 1, mirror on RAID 0 and
MirrorWriteDB=Sequential
4 - Other options?
What's the performance impact of having TSM do the mirroring? Since I'll be
moving the DB to a storage array (HP EVA) which can self replace failing
disks I'm tempted to go for option 2
Thanks in advance!
Regards
Alex
