Abstract: 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.

Abstract: A method, computer program product, and computing system for defining a first server and a second server within a server cluster. The first server includes a first cache system and the first and second servers are coupled to a data array that includes a LUN. The LUN is reserved for exclusive access by the first server, thus generating a first server reservation. Data associated with the LUN is cached within the first cache system of the first server. A loss of the first server reservation is sensed. In response to a loss of the first server reservation, the first cache system of the first server is purged.

Abstract: Example embodiments of the present invention relate to a method, an apparatus, and a computer program product for directing I/Os for a chunk of data to a data storage system on which the chunk of data is stored. The host method includes receiving an I/O for a chunk of data, identifying to which data storage system the I/O should be sent to access the chunk of data, and sending the I/O for the chunk of data to the identified data storage system. Other example embodiments of the present invention relate to a method, an apparatus, and a computer program product for handling received I/Os during a migration of the chunk of data. The data storage system method includes migrating the chunk of data, queuing an I/O for the chunk of data received from a host during the migration, and rejecting the queued I/O as a result of the migration.

Abstract: A method, computer program product, and computing system for defining a storage space having a defined capacity within a storage system. The storage system includes a frontend system and a backend system. A first portion of the storage space is located within the frontend system. A second portion of the storage space is located within the backend system. Usage of a data item stored within the storage space is monitored to identify a usage pattern. The data item is migrated to either the first portion of the storage space or the second portion of the storage space based, at least in part, upon the usage pattern.

Abstract: Example embodiments relate to methods, systems, and a computer program product for detecting and responding to the presence of malware persistently executing in a monitored virtual machine of a virtual computing platform. The method includes logging I/O requests at a hypervisor kernel in a kernel log and at a virtual machine (VM) managed by the hypervisor in a VM log. The logged I/O requests then may be compared to detect evidence of malware according to differences between the I/O requests logged in the VM log and the kernel log.

Abstract: 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.
