System, apparatus, and method for enhancing storage management in a storage area network

摘要

The invention provides a system, apparatus and procedure whereby a controller manages computer access to a number of storage volumes in a storage peripheral. To accomplish this, a system administrator assigns a plurality of port IDs to a disk array controller, the disk array controller being responsive to requests from a computer using any of the plurality of port IDs. Next, the system administrator configures a data structure in a memory of the controller such that at least a subset of the plurality of port IDs are mapped to particular ones of the number of storage volumes. Next, in response to an access request by a computer, wherein the access request specifies a target port ID, the controller grants the computer access to only those storage volumes whose mapped port ID corresponds to the target ID.
