    摘要: Methods and systems for processing task management requests are provided. A cache client adapter receives a task management request other than an abort for a logical storage object owned by a cache owner adapter and determines if there are any pending input/output (I/O) requests associated with the storage object. The cache client adapter sends an abort request to the cache owner adapter when there are pending I/O requests and sends the task management request directly to a controller that manages a storage device whose space is presented as the logical storage object; and sends only the task management request to the controller when there are no pending I/O requests for the logical storage object.

    摘要: Methods and systems for managing logical storage object reservation requests are provided. A controller of a storage array having a storage device for storing information on behalf of the logical storage object communicates with a first adapter via a network connection. The controller grants ownership of the logical storage object to the first adapter by the controller. A second adapter that interfaces with the first adapter is notified by the first adapter regarding the granted ownership. The second adapter is configured to send a request for reserving the logical storage object to the first adapter, where the second adapter sends the request on behalf of an application for reading, writing or both reading and writing at the storage space using the logical storage object. The first adapter receives and processes the request.

    摘要: Methods and systems for synchronous replication of data are provided. A master intelligent storage adapter operating within a cluster having a slave intelligent storage adapter receives a plurality of write requests; generates a first input/output (I/O) request for storing the data for the plurality of write requests at a first storage device; and generates a second I/O request for a replication module executed by a computing device for synchronously storing the data at a second storage device. The computing device initiates a synchronous replication operation to replicate the data for the plurality of write requests at the second storage device.
