Continuous servicing of input/output request for a volume set having failed on a primary array using either portions of the failed volume set or a mirrored volume set is provided. A determination is made whether the failed volume set can service the input/output request and continuous data availability is provided by using the failed volume set to process the input/output request when the failed volume set can service the input/output request, else using a remote mirrored volume set to process the input/output request.

Abstract: An apparatus, method, and system for speculative data mirroring include a rollback log that receives write data corresponding to a write operation that is directed to a storage region within a source volume. Also included is a storage control module that initiates a lock operation on a corresponding storage region within a target volume and a mirror control module configured to send the data corresponding to the write operation to the target volume without waiting for feedback regarding the lock operation. In one embodiment, initiating a lock operation may include sending a lock command to the target volume. Alternatively, the data corresponding to the write operation may initiate the lock operation. In addition, the mirror control module may initiate retransmission of the data in response to subsequent execution of the lock operation. Due to the unique configuration of the present invention, the present invention reduces latencies arising from synchronous mirroring operations, such as lock operations.

Abstract: An apparatus, system, and process are disclosed for maintaining data in an electronic storage array during multiple, concurrent drive failures. A first drive failure is recognized and the storage system controller subsequently enters a first operating mode. The storage system controller then recognizes a second drive failure and enters a second operating mode, which is different from the first operating mode, in response to the second drive failure. The second operating mode allows the storage system controller and a recovery module to access the data of the second failed drive in a controlled manner in order to attempt to recover the data on the first failed drive. Also, a pinned data module may allow write data to be written to a pinned data drive, instead of a failed drive, while the storage system controller is operating in the second operating mode.

Abstract: Provided is a method, system, and program implemented by a server for controlling and providing access to a file to at least one remote computer over a network. The server maintains metadata about files. The files are maintained at remote storage locations. The server receives a request from the remote computer for a filename of a requested file over the network.
