    Abstract: Even if abnormality occurs in part of a plurality of data processing resources, data processing is executed by using a normal resource(s). Each of a plurality of storage apparatuses includes a host communication control unit, a controller, and a storage device communication control unit. If abnormality occurs in the host communication control unit of a local system or the storage device communication control unit of the local system, the controller of each system selects a normal resource, as a resource to be used for processing after the occurrence of the abnormality, from the host communication control unit of the local system or the storage device communication control unit of the local system, executes processing of a command for the local system, which is issued from a host computer after the occurrence of the abnormality, by using the selected resource, and requests the storage apparatus of the other system via a data transfer path to execute part of the processing of the command for the local system.

    Abstract: A media area network (10) includes a storage system (16) having at least one storage device (18) for storing digitized information. A host bus (14) adapter provides a link between the storage system and a host system (12) that provides overall control of the media area network. Within the host bus adapter, a lower-level port driver (24) monitors communications between the storage system and the host bus adapter. In the event of a communications failure, the lower-level port driver initiates switching from a failed port to an alternative port, thereby achieving fail-over recovery. Allocating the responsibility for fail-over recovery to the lower-level port driver assures timely handling of port failures, thereby reducing potential latency delays.

    Abstract: A method for reducing the time necessary to recover from a processor (111, 121) failure in a fault-tolerant computer system with redundant server computer systems (110, 120) with their own disk storage systems is disclosed and claimed. In normal operation whenever data is to be written to disk storage, each of the servers writes an identical copy of the data to its own disk storage system. When a server processor fails and then is restored to operation, that server's disk storage system must be made identical to (consistent with) the disk storage system of the non-failing server before the system is again fault tolerant. This method improves performance by electronically transferring the disk storage system from the failing server to a non-failing server, having the non-failing server keep the transferred disk storage system identical to its normal disk storage system, and reconnecting the transferred disk storage system to the failed server when it again becomes available. This minimizes the processing time required to make the disk storage contents identical, both at the time of failure and at the time of restoration.

    Abstract: The disk array control system is a fault tolerant controller for arrays of hard disk drives. With the controller (8) as a front end, an array of hard disk drives (12) would appear as a single drive to a host computer system (7) connected to the controller. The controller translates input/output data requests (300) from the host system (7) to input/output data transfer requests for the appropriate drives in the drive array (12). To minimize latency, translation techniques provide for a minimal number of accesses to the drives in the array. Queued input/output requests are supported, and, to maximize throughput, optimal scheduling techniques are used to optimize resource usage and minimize drive access overheads. Means are provided for detecting module failures, sustaining operation after failure, and replacing faulty modules without interrupting service.
