Estimating the term…
A method for more efficiently utilizing storage space in a set of storage drives is disclosed. In one embodiment, such a method implements, in a set of storage drives, a first RAID utilizing data striping with distributed parity values. The method further implements, in a subset of the set of storage drives, a second RAID using residual storage space in storage drives belonging to the subset. Storage drives belonging to the subset may have a storage capacity that is larger than storage drives not belonging to the subset. In certain embodiments, the method adaptively alters a parity rotation of the first RAID to provide an increased concentration of parity values in certain storage drives of the first RAID compared to other storage drives of the first RAID. A corresponding system and computer program product are also disclosed.
