MANAGING WORKLOAD TO PROVIDE MORE UNIFORM WEAR AMONG COMPONENTS WITHIN A COMPUTER CLUSTER

摘要

A method and a computer program product for implementing the method are provided for wear leveling the physical servers or other components within a cluster. The method includes identifying uptime for each of a plurality of physical servers within a cluster and scheduling jobs on the physical servers within the cluster giving priority to the use of physical servers in order of increasing uptime. The physical servers within the cluster that have no assigned jobs are then powered off. As a result, physical servers having low uptime relative to other physical servers within the cluster will operate more so that their uptime increases, and physical servers having high uptime relative to other physical servers within the cluster will operate less so that their uptime does not increase. Over time, the method will narrow the range of uptime, which may be referred to as “wear leveling.”
