METHOD, APPARATUS AND NETWORK SYSTEM FOR MANAGING MEMORY RESOURCES IN CLUSTER SYSTEM

摘要

A method and an apparatus for managing the memory resources in a cluster system are provided, wherein the method for managing the memory resources in the cluster system includes: a requester sends a message for requesting remote cache to an arbitration server, wherein the message for requesting the remote cache includes the remote cache capacity required by a local virtual machine; the requester receives the provider information sent by the arbitration server, wherein the provider information is obtained by the arbitration server according to the idle memory information reported by a physical host in the cluster system and the remote cache capacity required by the local virtual machine; according to the provider information, the requester utilizes the idle memory of the provider, wherein the requester and the provider are different physical hosts in the cluster system. By using the technical solution provided in the embodiments of the invention, the utilization rate of the memory resources in the cluster system can be improved.
