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.
