HP Integrity Superdome server virtualization
Server virtualization enables administrators to increase the usage and simplify the management of single-server or multiple-server environments by configuring them as reusable pools of resources. Virtualization is an approach to IT that pools and shares resources so utilization is optimized and supply automatically meets demand.
One key solution for enabling an infrastructure of this nature is the HP Virtual Server Environment (VSE), which offers increased return on IT investment by improving server resource utilization in real time according to business priorities. In addition to increased server utilization, the HP Virtual Server Environment also enables rapid deployment of computing resources, improves availability, and significantly reduces costs.

The core functionality of the VSE is delivered by the intelligent policy engine, HP-UX Workload Manager, which continuously assesses whether a server environment is meeting its service-level objectives (SLOs) and either advises administrators or adjusts resources automatically when SLOs are not met. This base functionality is enhanced by the VSE’s ability to orchestrate the real-time allocation of all virtual server resources—partitions, on-demand solutions, and cluster solutions—assigned to executing applications, users, and processes.
VSE includes a number of fully integrated, complementary components that enhance the functionality and flexibility of your server environment. These include:
HP-UX Workload Manager (HP-UX WLM), an intelligent policy engine, performs real-time assessment of resource usage and advises and acts based on SLOs and business priorities to adjust the supply of resources according to demand.
