MEMORY CACHE FOR DISAGGREGATED MEMORY

Abstract:

A memory control system comprises a memory cache and a disaggregated memory pool including a plurality of physical memory media configured to provide volatile data storage for any of a plurality of compute nodes communicatively coupled with the disaggregated memory pool. Processing componentry of the memory control system is configured to populate the memory cache with data items stored by the plurality of compute nodes within the disaggregated memory pool according to a cache fill policy. Upon receiving a memory read request for a data item stored in the disaggregated memory pool from a compute node, the memory cache and disaggregated memory pool are searched in parallel for the data item. Upon retrieving the data item from either the memory cache or disaggregated memory pool, the data item is provided to the compute node.
