Follow these recommendations to obtain the best I/O performance on VOB
hosts:
- Use disks with fast seek times and high rotational speeds.
- Where practical, dedicate a disk spindle for each VOB.
- For very busy VOBs on hosts running Linux® or the UNIX® system, dedicate two disk spindles
per VOB: one for the database and source pools, and one for the cleartext
and DO pools.
- Use stripe technology (RAID 0) for improved performance.
- Use mirroring (RAID 1) if high availability is required.
- Avoid RAID 5, unless your benchmarks show equal performance to RAID (0+1).
- Place VOB storage pools on a certified NAS device.
Consult your system documentation for details about how to use disk striping
and mirroring.
