Abstract:
1. A method for coercing disk drive capacity in a RAID (Redundant Array of Inexpensive Disks) configuration, comprising: determining actual disk drive capacities of a first disk drive and a second disk drive in the RAID configuration; and if the actual disk drive capacities of the first disk drive and the second disk drive differ, multiplying the smaller actual disk drive capacity by a coercion ratio to establish an optimal disk drive capacity, the optimal disk drive capacity setting a minimum capacity threshold for any disk drive utilized within the RAID configuration; if the actual disk drive capacities of the first disk drive and the second disk drive are an equal value, multiplying the value by the coercion ratio to establish the optimal disk drive capacity; wherein the coercion ratio is a quotient of a first interpreted value for a number of bytes in a unit of disk drive capacity measurement and a second interpreted value for a number of bytes in the unit of disk drive capacity measurement.
