Abstract
A computer-implemented method and system for affinity based optimization of persistent memory volumes. Responsive to receiving a request for a parent virtual PMEM device, a total memory capacity is apportioned amongst virtual persistent memory (PMEM) resources and physical memory resources. In accordance with a target affinity characteristic, a set of virtual central processor unit (CPU) sockets are assigned. Each virtual CPU socket is configured based on at least one physical central processor unit (CPU) core in conjunction with a subset of the virtual PMEM and physical memory resources. Child virtual PMEM devices are created for respective ones of the virtual CPU sockets, each of the child virtual PMEM devices being dedicated to the parent virtual PMEM device.
