Summary


Just as the Space Shuttle Flight Control Room is the base for the flight-control team that manages and monitors all operations of the space shuttle, gWLM is the base for monitoring and managing the workloads in an enterprise datacenter. gWLM provides powerful capabilities for defining how resources should be allocated to workloads and the policy that dictates how those resource allocations are modified, if at all, based on resource utilization.

gWLM can be used to migrate CPUs between virtual partitions based on the resource utilization within each vPar. In addition, gWLM is capable of managing both fair-share scheduler groups and processor sets within an operating system instance. Linux support is provided through the use of a feature of the 2.6 version of the Linux kernel known as CPU affinity, which has similar characteristics to HP-UX PSETs. Finally, gWLM is also supported on OpenVMS.

Within HP's Virtual Server Environment, gWLM serves as the flight-control room for managing workloads and their resource allocation.
