HP Global Workload Manager

The HP Virtual Server Environment (VSE) is an integrated solution for both HP 9000 and HP Integrity server platforms that delivers the highest degree of integrated virtualization for allowing your business to quickly respond to changing business demands. Through the seamless integration of several virtualization technologies, VSE provides a flexible computing environment that maximizes usage of server resources. Since management of the VSE is automated, it provides an environment that dynamically grows and shrinks based on the requirements of your business applications.

HP Global Workload Manager (gWLM) is a multi-system, multi-OS workload manager, an intelligent policy engine in the HP Virtual Server Environment. It will integrate with resource management (whole processor and sub-CPU allocation mechanisms within a single operating system) and virtual partitioning techniques to dynamically reallocate resources to applications based on application performance or business policy. This will improve server utilization while maintaining and monitoring service levels across many servers.

HP Global Workload Manager has been designed for data center environments where a central IT organization is acting as a service provider to internal customers. gWLM will allow standard resource allocation policies to be quickly and easily deployed across a consolidated, virtualized data center.
