Abstract
Methods and associated structure operable within a SCSI-based storage subsystem are provided to adapt the storage controller for use with non-SCSI storage enclosures. A firmware layer of the present invention intercepts SCSI read/write requests and pass-through command blocks (CDBs) generated by the storage management core of the controller and translates the requests and command structures into corresponding command structures for transmission to a non-SCSI storage enclosure. In like manner, the firmware layer of the present invention receives status information from non-SCSI storage enclosures and translates the status information into corresponding SCSI compatible status information. In one exemplary preferred embodiment, a storage subsystem designed for interaction with SCSI storage enclosures may be adapted in accordance with the present invention to utilize lower-cost, IDE compatible storage enclosures.
