Abstract: A method and system for processing Service Level Agreement (SLA) terms in a caching component in a storage system. The method can include monitoring cache performance for groups of data in the cache, each the group having a corresponding SLA. Overfunded SLAs can be identified according to the monitored cache performance. In consequence, an entry can be evicted from among one of the groups which correspond to an identified one of the overfunded SLAs. In one aspect of the present invention, the most overfunded SLA can be identified, and an entry can be evicted from among the group which corresponds to the most overfunded SLA.
