As more and more software applications are migrating from local desktops to remote data centers,efficient data centers management is becoming increasingly *** management of data centers has been facing a key challenge how to trade-off power consumption and Quality of Service (QoS) of *** deal with this challenge,there has been a lot of ongoing efforts on power-aware and QoS-aware application *** on these works,we present I/O-Intensive and CPU-Intensive applications hybrid deployment to optimize resource utilization within virtualization environments. In this work,we investigate the resources allocation between virtual machines where I/O and CPU-Intensive applications reside,to achieve power-aware applications hybrid deployment. To demonstrate the problem of I/O and CPU resource in virtualization environment,we use Xen as the Virtual Machine Monitor to do *** different resource allocation configurations,we evaluate power efficiency up to 2%~12%, compared to the default *** also can conclude the more CPU resource that the CPU-Intensive application in the hybrid deployment applications need to satisfy QoS,the more power efficiency improvement that hybrid deployment can bring.

Particle swarm optimization(PSO) is one of the modern heuristic *** has attracted great attention due to its features of easy implementation,robustness to control parameters and computation efficiency compared with other existing heuristic *** performance of a PSO can depend on its parameters such as the inertia weight factors and two acceleration *** value of inertia weight can treat the balance between exploration and exploitation,so a proper control of inertia weight is very important to find the optimum solution *** paper compared several kinds of inertia *** results demonstrate that simulated annealing inertia weight and linearly decreasing inertia weight have better convergence performance in the searching procedure. The dimension of the solution has no effect on the performance of inertia *** performance of the two kinds of inertia weight will change when the benchmark functions and acceleration coefficients change.
