Abstract
A redundant array of independent drives (RAID) stripe is formed across a set of storage controllers of a plurality of storage controllers, wherein the RAID stripe comprises two or more of a plurality of modular storage devices of at least one of the set of storage controllers. The RAID stripe is written across the set of storage controllers.
Claims20
A storage system comprising:
- a plurality of storage controllers, wherein each of the plurality of storage controllers is configured to support a plurality of modular storage devices;
- and
- a storage system controller operatively coupled to the plurality of storage controllers, the storage system controller comprising a processing device, the processing device to:
- form a redundant array of independent drives (RAID) stripe across a set of storage controllers of the plurality of storage controllers, wherein the RAID stripe comprises two or more of the plurality of modular storage devices of at least one of the set of storage controllers;
- and
- write the RAID stripe across the set of storage controllers.
3 more elements
A method, comprising:
- forming, by a processing device of a storage system controller, a redundant array of independent drives (RAID) stripe across a set of storage controllers of a plurality of storage controllers, wherein the RAID stripe comprises two or more of a plurality of modular storage devices of at least one of the set of storage controllers;
- and
- writing the RAID stripe across the set of storage controllers.
A non-transitory computer readable storage medium storing instructions, which when executed, cause a processing device of a storage system controller to:
- form, by the processing device of the storage system controller, a redundant array of independent drives (RAID) stripe across a set of storage controllers of a plurality of storage controllers, wherein the RAID stripe comprises two or more of a plurality of modular storage devices of at least one of the set of storage controllers;
- and
- write the RAID stripe across the set of storage controllers.
