Field Description

Fault Tolerance For 1 disk drive = No

For 2 or more disk drives = Yes

Spare For 1-3 disk drives = No

For 4-8 disk drives = Yes

Optimization For 1 disk drive = Performance (no fault

tolerance)

For 2 disk drives = Performance

For 3 or more disk drives = Capacity

Logical Drive Count 1

Total (Useable) Capacity Depends on the fault tolerance overhead:

For 1 disk drive of n GB = n GB

For 2 disk drives of n GB = n GB

For 3 disk drives of n GB = 2n GB

For 4,5,6,7,8 disk drives of n GB =

2n,3n,4n,5n,6n GB respectively

a. With four or more drives, one drive’s capacity is used for fault tolerance

overhead, and one additional drive is reserved as a spare.

Disk Drive Identification Depends on disk drives.
