 US Patent 11714572 Optimized data resiliency in a modular storage system

Article

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.
