REDUNDANT ARRAY OF INDEPENDENT DISKS SYSTEM, METHOD FOR WRITING DATA INTO REDUNDANT ARRAY OF INDEPENDENT DISKS SYSTEM, AND METHOD AND SYSTEM FOR CREATING VIRTUAL DISK

摘要

A redundant array of independent disks (RAID) system stores data mapped to a virtual disk, where the virtual disk includes a plurality of virtual sub-disks. The RAID system includes a plurality of storage devices and a controller. The controller is electrically connected to the storage devices, and is utilized for configuring the storage devices into a plurality of zone stripes, where each storage device includes a plurality of zones, each zone stripe includes one zone of each of the storage devices, and each zone stripe stores data mapped to a portion of data of each of the virtual sub-disks.
