    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: 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: 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: 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.

    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: A method, computer program product, and computing system for receiving a read request on a first cache system, wherein the read request identifies previously-written content included within a data array. The previously-written content identified in the read request may be obtained from the data array. The previously-written content identified in the read request may be compressed, thus generating compressed previously-written content. A compression ratio may be determined for the compressed previously-written content.

    摘要: Described are techniques for partitioning storage of a data storage system. A plurality of storage groups is selected. Each of the plurality of storage groups includes one or more devices and is associated with an allocation policy including a first threshold specifying one of a minimum or a maximum amount of storage of a first of a plurality of storage tiers. Workload data for the plurality of storage groups is analyzed. Storage of a plurality of storage tiers is partitioned for use by the plurality of storage groups in accordance with criteria. The criteria includes workloads of the plurality of storage groups and the allocation policy associated with each of the plurality of storage groups.
