Abstract
Devices (e.g. “servers”) in a data storage system access data contained in logical volumes contained in a plurality of storage devices or storage arrays. The servers issue access requests through any available transfer path from the servers to the storage devices or storage arrays. I/O (input/output) devices control access between the servers and 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.
