From IT BusinessEdge, HP offers a white paper for more efficient server utilization.
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.
