Abstract
A technique provides a RAID resiliency set from a plurality of storage devices. The technique involves identifying a minimum sub-RRS width based on a predefined RAID level to be enforced on the RRS. The technique further involves, based on the minimum sub-RRS width, allocating segments from the plurality of storage devices to create a maximum number of sub-RRSs. The technique further involves forming the RRS from the created maximum number of sub-RRSs.
