Management of server cache storage space

摘要

An application server can be configured to access data stored on a networked storage server that is accessible over a network and that includes a cache device configured to store data received from the networked storage server. The application server can include a cache management module that is designed to monitor a data access requests transmitted over the network, the data access requests specifying a first page of data. In response to an indication that the requested data includes data stored in the cache device as an existing page of data, the first page of data can be mapped to a location corresponding to the existing page.

主权项

1. A computer implemented method comprising:
identifying at a first time that a first page of data within at least one networked storage server is a duplicate of a second page of data stored within the at least one networked storage server, the identifying being performed by a deduplication server configured to monitor requests to access the at least one networked storage server; detecting a request transmitted over a network at a second time to the at least one networked storage server, the request requesting that the first page of data stored on the at least one networked storage server be provided to an application server, wherein the first time is before the second time; and in response to detecting the request, providing the indication to the application server over the network, the indication indicating that the first page of data is a duplicate of the second page of data stored within a cache that is locally accessibly by the application server relative to the network.
