POOLED MEMORY CONTROLLER FOR THIN-PROVISIONING DISAGGREGATED MEMORY

Abstract:

A thin-provisioned multi-node computer system comprising a disaggregated memory pool and a pooled memory controller. The disaggregated memory pool is configured to make a shared memory capacity available to each of a plurality of compute nodes. The pooled memory controller is configured to assign, to each compute node of the plurality of compute nodes, a portion of the disaggregated memory pool such that a currently assigned total of assigned portions of the disaggregated memory pool is less than the shared memory capacity. The pooled memory controller is further configured to receive a request to assign an additional portion of the disaggregated memory pool such that the currently assigned total and the additional portion would exceed a predefined threshold amount of the shared memory capacity, to un-assign an assigned portion of the disaggregated memory pool, and assign the additional portion of the disaggregated memory pool.
