    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 描述了根据静态策略将第一数据存储到逻辑数据的技术，以使用存储在第一存储区域中的数据来进行服务读取。 逻辑设备将其数据存储在第二物理设备上的镜像上。 第一和第二物理设备中的每一个包括第一存储区域和第二存储区域。 第一个存储区域提供比第二个存储区域更好的性能。 第一数据被存储在物理设备之一的第一存储区域之一的第一位置处，并且存储在第一和第二物理设备中的另一个的第二存储区域之一的第二位置处。 通过访问存储在一个物理设备的第一区域中的第一数据来服务读取第一数据的操作。

    Abstract: 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.

    Abstract: Guaranteeing space availability for thin devices includes reserving space without committing, or fully pre-allocating, the space to specific thin device ranges. Space may be held in reserve for a particular set of thin devices and consumed as needed by those thin devices. The system guards user-critical devices from running out of space, for example due to a “rogue device” scenario in which one device allocates an excessive amount of space. The system uses a reservation entity, to which a thin device may subscribe, which reserves space for the thin device without allocating that space before it is need to service an I/O request.

    Abstract translation: 确保薄型设备的空间可用性包括预留空间，无需提交或完全预分配给特定的薄设备范围的空间。 空间可以保留一些特定的薄设备，并根据需要消耗这些薄的设备。 该系统防止用户关键设备运行的空间不足，例如由于一个设备分配了过多的空间的“流氓设备”场景。 该系统使用一个预订实体，薄设备可以订阅该预留实体，该预留实体在需要为I / O请求提供服务之前为该设备预留空间而不分配该空间。

    Abstract: 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.
