19.2 Maximize Disk Performance

Follow these recommendations to obtain the best I/O performance on the ClearCase LT server:

• Use disks with fast seek times and high rotational speeds.

• Where practical, dedicate a disk spindle for each VOB.

• For very busy VOBs, dedicate two disk spindles per VOB if the VOB server host provides such a feature: one for the database and source directories, and one for the cleartext and DO pools.

• Use stripe technology (RAID 0) for improved performance.

• Use mirroring (RAID 1) if high availability is desired.

• Avoid RAID 5, unless your benchmarks show equal performance to RAID (0+1).

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