Currently, virtualization is one of the most talked about new technologies in IT infrastructure. The ability to virtualize servers and to reclaim excess capacity has caught the interest of datacenter managers for many reasons, including more efficient processing and better resource utilization, reduced power/cooling costs, and improved management capabilities. The server virtualization marketplace has been evolving rapidly, and IDC has seen customer adoption of x86 server virtualization mature rapidly - with the average number of virtual machines (VMs) per physical server increasing, the types of workloads trending toward enterprise applications, and the hypervisor being leveraged for extended use cases such as high availability and disaster recovery.
