You are given 4 spindles to place TSM DB on them. How would you set them up to squeeze maximum performance for DB?
1. Dedicate each spindle for a DBC (result: 3 DBCs, one spindle left out, nevermind) 2. Create RAID 0 out of each pair of disks. Place a DBC on each RAID (result: 2 DBCs on two separate RAID 0) 3. Create RAID 1 out of each pair of disks. Place a DBC on each RAID (result: 2 DBCs on two separate RAID 1) 4. Create RAID 5 out of all spindles. Place one DBC on the RAID (result: 1 DBC on RAID5) Notes: a. There is no RAID 0+1 c. Wasted space is not a concern -- Warm regards, Michael Green
