Assignee: DELL PRODUCTS L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A method comprising:
organizing non-volatile drives into drive clusters, each having G non-volatile drives with G subdivisions, where G equals a number of data members and parity members of an implemented RAID level;
creating a G*G drive matrix for each of the drive clusters, the drive matrix representing the corresponding drive cluster;
creating a G×G overlay matrix in which a value at row R, column C equals a remainder of (R+C−2) divided by G, such that there are G distinct values in a range of 0 to G−1; and
responsive to addition of N new drives to one of the drive clusters, adding the N new drives to the corresponding drive matrix and using the overlay matrix to relocate RAID members within the drive matrix.
