Improving VOB host performance
Maximize disk performance

Maximize disk performance

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 NAS device.

Consult your system documentation for details about how to use disk striping and mirroring.
