Abstract: A storage controller for cache management that includes a cache memory and a cache management module. The cache management module to, on receipt of region specification requests from hosts, extract from the region specification requests cache rules for management of regions of data storage of a storage array, and on receipt of data operation requests from hosts, process the data operation requests based on the extracted cache rules.

Abstract: In some examples, techniques for virtual storage includes configuring a single physical storage disk to a virtual storage device that includes a plurality of virtual storage disks from a command specifying storage characteristics of the virtual storage disks including number of virtual storage disks, virtual strip size, and fault tolerance of the virtual storage disks. In response to access the virtual storage disks and specifying a virtual storage disk Logical Block Address (LBA), converting the virtual storage disk LBA into a physical storage disk LBA based on a sum of factors that includes a first factor comprising a modulo of the virtual storage disk LBA and virtual strip size, a second factor comprising number of virtual storage disks multiplied by a result of the virtual storage disk LBA minus the first factor, and a third factor comprising a virtual storage disk number multiplied by the virtual strip size.
