In storage virtualization virtual disk (VD) or vdisk is a virtual logical disk or volume with which a computer or application performs I/O operations. Generally it is provided by a storage-virtualization device that is a part of storage area network (SAN).[citation needed] As of 2012 the term vdisk is used in HP EVA disk arrays[citation needed] and in IBM SAN Volume Controller.The disk is classed as virtual due to the way it maps to the physical storage capacity it represents.
