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
