Abstract
Disclosed herein is an apparatus for managing disaggregated memory, which is located in a virtual machine in a physical node. The apparatus is configured to select, depending on the proportion of valid pages, direct transfer between remote memory units or indirect transfer via local memory for each of the memory pages of the source remote memory to be migrated, among at least one remote memory unit used by the virtual machine, to transfer the memory pages of the source remote memory to target remote memory based on the direct transfer or the indirect transfer, and to release the source remote memory.
