Modeling Analysis of Virtual Service Consolidation Based on Workload Timesharing Analyzing

A solution of virtual service consolidation oriented to next generation green data center is introduced in this paper. Due to the peak-valley of the workload of services is in different time, a way to problem modeling is proposed based on workload timesharing analysis, which can achieve maximal resource utilization on the premise of keeping the required QoS. Meanwhile, the associated services and the mutual services, and the compatibility between services and servers are taken into account and five principles of consolidation are considered. By regarding the modeling as a multi-dimension bin packing problem with constraints, we propose a GGA-based heuristic to search for the global optimal solution. The experimental results show that the solution can get a better consolidation ratio than the former model.
