Abstract
Data storage space in a data storage system is represented to the devices that access the data (e.g. 'servers') as a single virtual storage device containing logical volumes of data, even though the storage space is typically formed from several storage devices and possibly from arrays of storage devices containing multiple volumes of data. Therefore, the servers can issue the access requests through any available transfer path from the servers to the virtual storage device. However, I/O (input/output) devices control access between the servers and the devices that control access to the data (e.g. 'array controllers'), so that the access requests from the servers are uniformly routed to the preferred array controllers independently of the transfer paths through which the servers issue the access requests.
