    摘要: Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. Migrating data from an old storage device to a new storage device may also include creating new volumes on the new storage device and transferring data from the old storage device to the new storage device. Migrating data from an old storage device to a new storage device may also include dismantling the old paths.

    摘要: Migrating data from an old storage device to a new storage device includes transferring the data from a first logical device on the old storage device to a second logical device on the new storage device, determining replication relationships for the first logical device, transferring the replication relationships; and transferring logical devices used for the replication relationships from the old storage device to the new storage device. The replication relationships may include a clone of the first logical device. Migrating data from an old storage device to a new storage device may also include suspending writes to the first logical storage device prior to transferring the data for the first logical storage device. The replication relationships may include at least one snapshot.

    摘要: A system having a plurality of directors, at least some of which have a local director memory, accesses requested data by determining if requested data is in local director memory of a first one of the directors in response to an access request for the requested data by the first one of the directors. The system also determines if the requested data is native to the first one of the directors in response to the requested data not being in the local director memory of the first one of the directors, where data provided on a physical storage device coupled to the first one of the directors is native to the first one of the directors. The system also obtains the requested data from a second one of the directors in response to the requested data not being native to the first one of the directors.

    摘要: Described are techniques for storing first data to a logical data in accordance with a static policy to service reads using data stored in a first storage area. The logical device has its data stored on a first physical device that is mirrored on a second physical device. Each of the first and second physical devices include a first storage area and a second storage area. The first storage areas provide better performance than the second storage areas. The first data is stored at a first location in one of the first storage areas of one of the physical devices and at a second location in one of the second storage areas at the other of the first and the second physical devices. An operation to read the first data is serviced by accessing the first data stored in the first area of the one physical device.

    摘要: Described are techniques for caching. At a first point in time, a first set of data portions currently stored in a first cache of a first data storage system is determined. Each data portion of the first set is located on a first device of the first data storage system. Sent to a second data storage system is first information including information identifying a storage location on the first device for each data portion of the first set. The second data storage system includes a second device that is maintained as a mirror of the first device. The storage location for each data portion of the first set is used to identify a second storage location of the second device corresponding to the storage location. The first information is used to populate a second cache of the second data storage system.

    摘要: A method, computer program product, and computing system for receiving an indication of a cold cache event within a storage system. The storage system includes a multi-tiered data array including at least a faster data tier and a slower data tier. A data list that identifies at least a portion of the data included within the faster data tier of the multi-tiered data array is obtained from the multi-tiered data array. At least a portion of the data identified within the data list is requested from the multi-tiered data array, thus defining the requested data. The requested data is received from the multi-tiered data array.

    摘要: A data storage system capable of performing remote data services (e.g., data mirroring) over an IP network using native connections to the IP network is described. The data storage system employs an architecture that manages the remote data services and the native connections to the IP network in a way that isolates the remote data services application software from the TCP/IP and lower level network processing.
