International Classification:

G06F 15/167
G06F 12/08

US Classification:

709213, 711141, 711E12025, 711E12026

Abstract:

A computer network with distributed shared memory, including a clustered memory cache aggregated from and comprised of physical memory locations on a plurality of physically distinct computing systems. The network also includes a plurality of local cache managers, each of which are associated with a different portion of the clustered memory cache, and a metadata service operatively coupled with the local cache managers. Also, a plurality of clients are operatively coupled with the metadata service and the local cache managers. In response to a request issuing from any of the clients for a data item present in the clustered memory cache, the metadata service is configured to respond with identification of the local cache manager associated with the portion of the clustered memory cache containing such data item.

US Classification:

711130, 711E12038

Abstract:

A computer network with distributed shared memory, including a clustered memory cache aggregated from and comprised of physical memory locations on a plurality of physically distinct computing systems. The clustered memory cache is accessible by a plurality of clients on the computer network and is configured to perform page caching of data items accessed by the clients. The network also includes a policy engine operatively coupled with the clustered memory cache, where the policy engine is configured to control where data items are cached in the clustered memory cache.

International Classification:

G06F 12/08

US Classification:

711144, 711E12037

Abstract:

In one embodiment, a computing system includes a cache having one or more memories, a cache journal operable to store data associated with one or more portions of the cache, and a configuration manager operable to access the cache and the cache journal. The configuration manager is operable to determine whether the cache journal includes data associated with a first portion of the cache, and to create, in the cache journal, data associated with the first portion of the cache if the cache journal does not yet comprise data associated with the first portion of the cache. The configuration manager is also operable to determine whether the first portion of the cache is valid for use, and to communicate with a memory manager associated with the first portion of the cache regarding whether the first portion of the cache is valid for use.

Noelan Ray Olson - Portland OR, US

International Classification:

H04L 29/08
G06F 12/08

Abstract:

In one embodiment, a computer system includes a cache having one or more memories and a metadata service. The metadata service is able to receive requests for data stored in the cache from a first client and from a second client. The metadata service is further able to determine whether the performance of the cache would be improved by relocating the data stored in the cache. The metadata service is further operable to relocate the data stored in the cache when such relocation would improve the performance of the cache.
