    Abstract: A method, computer program product, and computing system for defining a portion of a frontend cache system for use as a data array cache portion. One or more cache slots included within a backend cache system are identified that are going to be overwritten with hot cache data and are currently filled with cold cache data. The cold cache data included within the one or more cache slots included within the backend cache system is written to one or more cache slots included within the data array cache portion.

    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. If the previously-written content identified in the read request is stored within the first cache system in a compressed format, and the previously-written content identified in the read request is stored within the data array in an uncompressed format; a determination is made as to if it is less computationally expensive to obtain from the data array the previously-written content in an uncompressed format.

    Abstract: 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.

    Abstract: A method, computer program product, and computing system for monitoring data requests made by an application being executed on a host to generate a prediction concerning a quantity of data that may be needed by the application in the future. The quantity of data is stored within a backend cache system included within a data array coupled to the host. The quantity of data is provided to the host.

    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. A read request content identifier associated with the previously-written content identified in the read request is received from the data array. The read request content identifier associated with the previously-written content identified in the read request is compared to a plurality of content identifiers included within a content directory for the first cache system to determine if a matching content identifier exists. Each of the plurality of content identifiers is associated with a piece of previously-written content included within the first cache system.

    Abstract: 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.
