Abstract
Fileserver buffers are managed so as to improve the hit ratio for read accesses to the fileserver by clients by grouping related files into filesets, collecting fileserver access operation (i.e., read and write) statistics for each of the filesets, classifying the filesets into a plurality of fileset categories having similar collected access operation statistics and then implementing different fileserver buffer management policies for the blocks (or pages) from each of the different fileset categories. The buffer management policy applied to each of these categories is designed to create a generally higher preference for retaining blocks (or pages) of files in the fileserver buffers having a generally higher read to write ratio.
