...on Data Center Efficiency

"Data Center Knowledge: What are things that can be done through virtualizing servers that can increase utilization and decrease cost?
Clemens Pfeiffer: The best and most efficient set-up is based on research and patents from PARC around shared reservation models and QoS (Quality of Service) levels of applications. Unlike static reservations, which do not respond to utilization and therefore are based on an allocation for peak demand, grouping critical and non-critical applications on the same cluster using a shared model will provide more flexibility and reliability by allowing critical applications to take over whatever they need from the cluster and non-critical applications to take the rest resulting in a much better consolidation than the typical 14:1 reduction."
