摘要： A method for operating a storage system, including storing data redundantly in the system and measuring respective queue lengths of input/output requests to operational elements of the system. The queue lengths are compared to an average queue length to determine respective performances of the operational elements of the storage system. In response to the average queue lengths and a permitted deviation from the average an under-performing operational element among the operational elements is identified. An indication of the under-performing operational element is provided to host interfaces in the storage system. One of the host interfaces receives requests for specified items of the data directed to the under-performing element, and in response to the indication, some of the requests are diverted from the under-performing operational element to one or more other operational elements of the storage system that are configured to provide the specified items of the data.

摘要： A method for conveying a Small Computer System Interface (SCSI) command from a host to a logical volume, the method consisting of incorporating an indication of an address of the logical volume in the SCSI command so as to generate a modified SCSI command. The method further includes conveying the modified SCSI command from the host to a target device, receiving the modified SCSI command at the target device and recovering the address from the modified SCSI command. In response to the recovered address, the SCSI command is executed at the logical volume.

摘要： The present invention combines IP multicasting mechanisms with SCSI protocols to achieve a more efficient data replication or data mirroring scheme. The combination of the IP multicast mechanism with the mapping of virtual unit logical number to real logical unit numbers, combined with the use of SCSI response frames, ensures the integrity of multicasted data. By use of the SCSI protocol over the TCP/IP according to the present invention, there is no further need to transfer multiple copies of the same data on the same communication link, and the routing logic may be removed from initiator and targets to IP routers.

摘要： A method for data storage includes accepting write commands belonging to a storage operation invoked by a host computer, and caching the write commands in a volatile memory that is powered by external electrical power. A current execution status of the storage operation is also cached in the volatile memory.Responsively to an interruption of the external electrical power during the storage operation, the cached write commands and the cached execution status are backed-up in a non-volatile memory. Upon resumption of the external electrical power, the backed-up execution status is recovered, so as to resume the interrupted storage operation.
