    摘要: A method and apparatus for accessing a virtualized storage volume are described. At least one volume map is copied to a virtualization switch prior to an application requesting access to a storage volume via the virtualization switch, where the volume map facilitates mapping the storage volume access request to an appropriate physical storage device and is copied from a source external to the virtualization switch.

    摘要: A method, system, and computer readable medium for maintaining the order of write-commands issued to a data storage, where the write-commands are issued by one or more host. In one embodiment of the present invention the method includes assigning an order-descriptor to each write-command, storing the write-command, storing the order-descriptor, and collating a plurality of order-descriptors and their corresponding write-commands to obtain an ordered write-command stream.

    摘要: Techniques for storage network bandwidth management are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for storage network bandwidth management comprising sampling, using at least one computer processor, application Input/Output (I/O) requests associated with the unit of storage during a specified period of time, determining a maximum latency value based on the sampling of the application Input/Output (I/O) requests, comparing the maximum latency value with a current latency value, and throttling administrative I/O requests in the event that the current latency value exceeds the maximum latency value.
