Using the traditional one-server-to-one-app approach to initialing servers means that most servers are only 5 to 15% loaded, resulting in under-loading of resources. By converting x86 servers into virtual machines that run independently of basic hardware, you can stop growing number of servers and increase their utilization rate.
Each virtual machine is a full-value computing system and can be governed by Windows, Linux, Solaris and NetWare, as well as variety of other applications. In addition, several virtual machines can run on single server. At the same time multiple workloads on powerful x86 servers, increase coefficient of server hardware from 10-15% to 80%.
