ABSTRACT:
A dynamic cache system is configured to flexibly respond to changes in operating parameters of a data storage and retrieval system. A cache controller in the system implements a caching policy describing how and what data should be cached. The policy can provide different caching behavior based on exemplary parameters such as a user ID, a specified application or a given workload. The cache controller is coupled to the data path for a data storage system and can be implemented as a filter in a filter framework. The cache memory for storing cached data can be local or remote from the cache controller. The policies implemented in the cache controller permit an application to control caching of data to permit optimization of data flow for the particular application.
