    摘要: A method includes computing, in a local storage system having a local volume with a plurality of local regions, respective local signatures over the local regions, and computing, in a remote storage system having a remote volume with remote regions in a one-to-one correspondence with the local regions, respective remote signatures over the remote regions. A given remote region is identified, the given remote region having a given remote signature and a corresponding local region with a given local signature that does not match the given remote signature. The data in the given remote region is then replaced with data from the corresponding local region.

    摘要: A method for migrating data to a mass storage system, including receiving an incoming data partition for storage in the mass storage system and allocating logical storage for the incoming data partition in the mass storage system. The method further includes making a determination that the incoming data partition includes only zero data, and, in response to the determination, inhibiting physical storage of the incoming data partition in the mass storage system while maintaining the allocated logical storage for the incoming data partition.

    摘要: A method for configuring transparent synchronous mirroring volume switching for a first volume and a second volume that are coupled, via a storage area network, to a host computer, with the first volume mapped to the host computer. The method includes initiating synchronization of status data between the first volume and the second volume, and setting the first volume to an active state. The second volume is set to an inactive state, and an identifier associated with the active first volume is copied to a memory coupled to the inactive second volume. The copied identifier is retrieved from the memory by the host computer, and the inactive second volume is then mapped to the host computer.

    摘要: A method for data distribution, including distributing logical addresses among an initial set of devices so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses. If a device is added to the initial set, forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set to the additional device. There is substantially no transfer of the logical addresses among the initial set. If a surplus device is removed from the initial set, forming a depleted set, the logical addresses oldie surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained.

    摘要: A method for managing a data storage system, consisting of configuring a first cache to retrieve data from and store data at a first range of logical addresses (LAs) in a storage device. A second cache is configured to operate like the first cache. The method further includes configuring one or more third caches to retrieve data from and store data at a second range of LAs in the storage device.The method includes detecting an inability of the second cache to retrieve data from or store data at the first range of LAs. In response to the inability, at least one of the first cache and the one or more third caches are reconfigured to retrieve data from and store at the first range of LAs while continuing to retrieve data from and store at the second range of LAs.
