Abstract
Each drive in a cluster is organized into splits of a single size. The splits are used as protection group members for a selected RAID level. Individual clusters can be scaled up with a number of new drives that is less than the number of protection group members for the RAID level by redistributing some data/parity to splits of the new drives. Splits are selected for redistribution such that new protection groups are created. If the number of new drives is equal to or greater than the number of protection group members for the RAID level, then new clusters may be created using the new drives. Any remaining drives are used to scale-up individual clusters.
