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
