Abstract
Corresponding performance characteristics for storage devices are identified. A calculation is performed using the corresponding performance characteristics for the storage devices. A set of storage devices is allocated for storage of shards of a redundant array of independent drives (RAID) stripe based on results of the calculation.
Claims20
A storage system, comprising:
- a plurality of storage devices;
- and
- a storage controller, operatively coupled to the plurality of storage devices, the storage controller comprising a processing device configured to:
- identify corresponding performance characteristics for the plurality of storage devices;
- perform a calculation using the corresponding performance characteristics for the plurality of storage devices;
- and
- allocate a set of storage devices of the plurality of storage devices for storage of shards of a redundant array of independent drives (RAID) stripe based on results of the calculation.

A method, comprising:
- identifying corresponding performance characteristics for a plurality of storage devices;
- performing a calculation using the corresponding performance characteristics for the plurality of storage devices;
- and
- allocating, by a processing device of a storage controller operatively coupled to the plurality of storage devices, a set of storage devices of the plurality of storage devices for storage of shards of a redundant array of independent drives (RAID) stripe based on results of the calculation.

A non-transitory computer readable storage medium storing instructions which, when executed, cause a processing device of a storage controller to:
- identify corresponding performance characteristics for a plurality of storage devices;
- perform a calculation using the corresponding performance characteristics for the plurality of storage devices;
- and
- allocate a set of storage devices of the plurality of storage devices for storage of shards of a redundant array of independent drives (RAID) stripe based on results of the calculation.
