Conventional IT architecture assumes a one-to-one mapping between a server and an application: "This is our database server. Over there is our data warehouse, and that one is our CRM server." Each environment is sized for a peak load that may be a single end-of-month run. Not surprisingly, IT studies have shown that the average server utilization rate is an incredibly low 20-35%. Wouldn't it be an interesting approach to break down the physical barriers, pool the resources, and share any excess capacity between applications as they need it? That is exactly what HP does with virtualization.The HP Virtual Server Environment (VSE) for HP Integrity and HP 9000 servers helps you achieve a greater return on your IT investments and gives you flexible capacity by optimizing server resource utilization in real time based on business priorities. The HP Virtual Server Environment provides a pool of virtual servers that can grow or shrink based on service level objectives and business needs.
