Configuring a cache prefetch policy that is controllable based on individual requests

摘要

Caching techniques for use in a computer system comprising a core and at least one edge device. The core comprises at least one object addressable storage system. At least one cache is disposed logically between the core and the edge device. The cache has a prefetch policy that selects from among the content units based upon at least one prefetch criterion. Prefetching can be enabled or disabled in response to at least one criterion based upon information associated with an individual access request.
