A generic storage container system is provided for a grid-based storage architecture, comprising a generic storage container comprising a plurality of storage domains along one axis against a plurality of rows of stripes along another axis defining a preselected storage capacity, and configuration information allocating the stripes in response to a storage format specified by an allocation request. A method is provided for storing the data, comprising: providing the generic storage container; providing configuration information adapted for selectively allocating the stripes in relation to a data storage format; specifying a desired storage format; and allocating the stripes in response to the desired format.

A method for implementing security management in a storage area network by controlling access to network resources. Initially, a resource provider communicates with potential resource users, such as host computers, servers, and workstations, to allow the users to discover the resources available on the storage area network. Resource users that have not previously logged in to a particular resource supply identification information to the resource provider, which places the information in a 'not yet approved entity' table. The 'not yet approved entity' table is made available to a management station. An administrator, using the management station, then determines whether to authorize use of resources. If access to the requested resource is allowed, the resource user identification information is stored in an &#x2018;approved entity&#x2019; table. A login is then allowed by the resource user to the selected resource. Once a resource user has initially logged in, connection information is maintained in the &#x2018;approved entity&#x2019; table facilitating subsequent log-in attempts by the resource user.

Provided herein is a method and apparatus for host transparent storage controller failover and failback. A controller is capable of assuming the identity of a failed controller while continuing to respond to its own SCSI ID or IDs in such a way that all SCSI IDs and associated units (LUNS) of the failed controller are effectively taken over by the surviving controller. This 'failover' behavior is transparent to any attached host computers and is treated by such attached hosts as a powerfail condition. The symmetric operation of returning the targets (IDs) and units (LUNs) to the previously failing controller ('failback') is likewise transparent.
