Utility analysis for Internet-oriented server consolidation in VM-based data centers

—Server consolidation based on virtualization technology will simplify system administration, reduce the cost of power and physical infrastructure, and improve utilization in today’s Internet-service-oriented enterprise data centers. How much power and how many servers for the underlying physical infrastructure are saved via server consolidation in VM-based data centers is of great interest to administrators and designers of those data centers. Various workload consolidations differ in saving power and physical servers for the infrastructure. The impacts caused by virtualization to those concurrent services are fluctuating considerably which may have a great effect on server consolidation. This paper proposes a utility analytic model for Internet-oriented server consolidation in VM-based data centers, modelling the interaction between server arrival requests with several QoS requirements, and capability flowing amongst concurrent services, based on the queuing theory. According to ...
