摘要： A method, computer program product, and computing system for processing one or more data chunks on a host server. The one or more data chunks are destined for storage within a portion of a data array coupled to the host server. The one or more data chunks are stored within a host cache system included within the host server. Storage criteria concerning the portion of a data array is reviewed. The storage criteria includes an array bandwidth allotment that defines a maximum bandwidth between the host server and the portion of the data array. The one or more data chunks are written to the portion of the data array based, at least in part, upon the storage criteria.

摘要： A host-based memory is maintained for a host computing device. Data obtained from a storage array in response to one or more read requests is stored in the host-based memory. The storage array includes an array-based memory and is configured to perform one or more data pre-fetch operations. The host computing device monitors for the occurrence of a set of sequential read requests. The set of sequential read requests is sent from the host computing device to the storage array when one or more read requests of the set of sequential read requests match data stored in the host-based memory. Thus, the storage array is enabled to perform one or more data pre-fetch operations in accordance with the array-based memory and the set of sequential read requests.

摘要： A method, computer program product, and computing system for storing a plurality of frontend data chunks within a cache system. The plurality of frontend data chunks correspond to a plurality of backend data chunks stored within a data array. A device weight is determined for each of the plurality of backend data chunks. The device weight is indicative of the type of storage device upon which each of the plurality of backend data chunks is stored within the data array. A deletion score is assigned to each of the plurality of frontend data chunks. Each deletion score is based, at least in part, upon the device weight determined for its corresponding backend data chunk.
