Method and system for cache management algorithm selection

DETAILED DESCRIPTION Against this backdrop embodiments of the present invention have been developed.
Embodiments of the present invention include a system and method of adaptively selecting algorithms utilized by a disc drive, depending on the host that issues the commands to the disc drive.
An embodiment of the present invention is a unique method of adaptively selecting an algorithm used in a disc drive to read or write data, depending on statistics of commands issued by the host computer.
By adapting the algorithm to the particular host, the data rate can be increased from the host's perspective.
One embodiment includes a cache manager having a configuration module, a set of cache management algorithms, and a recognition module.
The recognition module includes usage statistics, a correlator, a switch module, and a cache management executive.
The correlator detects a best match between the usage statistics and pattern data in the configuration module.
The switch module directs the cache management executive to execute the algorithms associated with the best matched pattern data.
These and various other features as well as advantages which characterize the present invention will be apparent from a reading of the following detailed description and a review of the associated drawings.
