In some embodiments, a non-volatile cache memory may include a segmented non-volatile cache memory configured to be located between a system memory and a mass storage device of an electronic system and a controller coupled to the segmented non-volatile cache memory, wherein the controller is configured to control utilization of the segmented non-volatile cache memory. The segmented non-volatile cache memory may include a file cache segment, the file cache segment to store complete files in accordance with a file cache policy, and a block cache segment, the block cache segment to store one or more blocks of one or more files in accordance with a block cache policy, wherein the block cache policy is different from the file cache policy.

Apparatus and method for segmented cache utilization

In some embodiments, an electronic system may include a cache located between a mass storage and a system memory, and code stored on the electronic system to prevent storage of stream data in the cache and to send the stream data directly between the system memory and the mass storage based on a comparison of first metadata of a first request for first information and pre-boot stream information stored in a previous boot context. Other embodiments are disclosed and claimed.

The controller may be configured to utilize the file cache segment in accordance with information related to the block cache segment and to utilize the block cache segment in accordance with information related to the file cache segment. Other embodiments are disclosed and claimed.

A method and system to perform caching based at least on one or more file-level heuristics. The caching of a storage medium in a caching device is performed by a cache policy engine. The cache policy engine receives file-level information of input/output access of data of the storage medium and caches or evicts the data of the storage medium in the caching device based on the received file-level information. By utilizing information about the files and file operations associated with the disk sectors or logical block addresses of the storage medium, the cache policy engine can make a better decision on the data selection of the storage medium to be cached in or evicted from the caching device in one embodiment of the invention. Higher cache hit rates can be achieved and the performance of the system utilizing the cache policy engine is improved.

Method and system to perform caching based on file-level heuristics

A mechanism is provided at a host system to allow multiple entities (clients) to send and receive messages of a particular class of management services in a switched fabric for scalable solutions.

Mechanism for allowing multiple entities on the same host to handle messages of same service class in a cluster

A mechanism is provided at a host node to implement redirection for Class Managers that do not reside on the host node in order to process incoming data messages accordingly in a switched fabric for scalable solutions.

Mechanism for implementing class redirection in a cluster

A method for discovering and mapping elements in a subnet of a data network fabric. A single data packet may be sent from a subnet manager and broadcast by switches to other elements. Every time the packet is copied and forwarded, the identifier of the element and the node it passes through are recorded. Replies are generated when the packets reach end nodes or are received a second time at a switch. The use of specific node inport identifier in the packet speeds the process and avoids duplication. A batch request may also be utilized in conjunction with the broadcast so that multiple requests can be processed by the nodes at the same time.
