Abstract
Table Vectored Parity (TVP) of the present invention is a new method for the allocation of parity check information in multi disk storage systems. This technique permits an optional selection by the end user to store parity check information on a subset of any number of disks ranging from 1 to N, where there are N disks in the system.
