General System Layout Tips
Multiple FWD SCSI adapters for 3590s (4 in use)
- 2 drives per adapter
- Define devices so that ADSM uses adapters in turn
Multiple SSA adapters for disks (5 in use)
DB on fastest drives available, dedicated adapter
Optimize disk volume layout for storage pools ...
- Have more disk volumes than concurrent clients
- Spread volume numbers down adapters rather than across
May be some benefits in mirroring versus RAID (must be weighed against costs for large capacity)
