A method system and program product for sending a hint from the server to the storage array, the hint relating access requests of data stored on the storage array, receiving the hint at the storage array, and updating information about the data stored on the storage array using the hint.

Host based hints

A computer-executable method, system, and computer program product for managing a flash cache module in a data storage system, wherein the data storage system is in communication with a data storage array, the computer-executable method comprising receiving a request to write a first data block to the flash cache module; analyzing the flash cache module to determine if there is a free portion of memory on the flash cache module for the first data block; and upon a negative determination, writing the first data block to a used portion of memory on the flash cache module.

Flash write amplification reduction

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.

System and method for cache management

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.

System and method for caching data

A method, computer program product, and computing system for associating a heatmap file with a multi-portion data file located on a data array. The heatmap file is configured to monitor the usage of each portion of the multi-portion data file. At least one portion of the multi-portion data file is used via a virtual machine executed on a first physical machine. The heatmap file is updated to reflect the usage of the at least one portion of the multi-portion data file.

A method, computer program product, and computing system for associating a tracking file with a multi-portion data file located on a data array. The tracking file is configured to monitor the status of each portion of the multi-portion data file. At least one portion of the multi-portion data file is modified via a virtual machine executed on a first physical machine. The tracking file is updated to reflect the modification of the at least one portion of the multi-portion data file.

A network with authentication implemented using a client health enforcement framework. The framework is adapted to receive plug-ins on clients that generate health information. Corresponding plug-ins on a server validate that health information. Based on the results of validation, the server may instruct the client to remediate or may authorize an underlying access enforcement mechanism to allow access. A client plug-in that generates authentication information formatted as a statement of health may be incorporated into such a framework. Similarly, on the server, a validator to determine, based on the authentication information, whether the client should be granted network access can be incorporated into the framework. Authentication can be simply applied or modified by changing the plug-ins, while relying on the framework to interface with an enforcement mechanism. Functions of the health enforcement framework can be leveraged to provide authentication-based functionality, such as revoking authorized access after a period of user inactivity or in response to a user command.

Authentication in a network using client health enforcement framework

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.

Sequential read request management in data storage system environment

A method, computer program product, and computing system for processing, on a host, a read request for a portion of a data file stored on a backend storage system. The portion of the data file is obtained from the backend storage system. The portion of the data file is divided into a plurality of file chunks based, at least in part, upon a file type. Each of the plurality of file chunks is compared to other file chunks stored within a frontend cache system associated with the host to identify unique file chunks within the plurality of file chunks. The unique file chunks are stored within the frontend cache system.

A method, computer program product, and computing system for monitoring an application being executed on a host to generate a prediction concerning a quantity of data that may be needed in the future. The quantity of data is requested from a data array coupled to the host. The quantity of data is received from the data array. The quantity of data is stored within a frontend cache system included within the host.

System and method for predictive caching

Embodiments of the invention provide techniques for basing access control decisions at the network layer at least in part on information provided in claims, which may describe attributes of a computer requesting access, one or more resources to which access is requested, the user, the circumstances surrounding the requested access, and/or other information. The information may be evaluated based on one or more access control policies, which may be pre-set or dynamically generated, and used in making a decision whether to grant or deny the computer access to the specified resource(s).

Network layer claims based access control

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.

A method, computer program product, and computing system for copying a content directory associated with a cache system from a volatile memory system to a non-volatile memory system. A plurality of data requests concerning a plurality of data actions to be taken on an electro-mechanical storage device associated with the cache system are received on the cache system. The content directory on the volatile memory system is updated based, at least in part, upon the plurality of data requests. The plurality of data requests are stored on tracking queue included within the electro-mechanical storage device.
