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
