Abstract

A method and an apparatus to store data patterns are presented. In one embodiment, the method includes searching a pattern repository to find prior copies of a pattern and to reference one of the prior copies, or insert a new copy, based on the access time of the prior copy and the effect on the sequential stream performance.
