Virtual disk drive system and method

摘要

A disk drive system, capable of dynamically allocating data in a pool of storage, comprising: a data storage subsystem; a plurality of user volumes comprising storage space from the data storage subsystem; and a disk manager having at least one disk storage system controller, wherein the disk manager is configured to: maintain a pool of storage comprising a matrix of virtual volumes of the data storage subsystem, each of the virtual volumes being an abstraction of multiple physical storage devices and having a predefined size; dynamically allocate free virtual volumes from the matrix of virtual volumes to the plurality of user volumes; and write data to the allocated virtual volumes.
