Intel Technology Brief Sample

Server virtualization is helping IT organizations improve data center productivity in fundamental ways. It lets you consolidate multiple operating systems and applications per physical server and deploy new applications in minutes. It also lets you move running applications from one server to another without downtime for flexible workload management, high availability and planned or unplanned maintenance.

The benefits in utilization, energy savings, manageability, service levels and cost models can be dramatic. Realizing the full value of virtualization requires servers that are built to handle the heavy demands of a virtualized and consolidated computing environment. Servers of just a few years ago were designed to host a single operating system. Successful virtualization with these systems requires software that can emulate a complete hardware environment for every guest operating system. This is a compute-intensive process that introduces significant performance overhead. It can slow application response times, limit scalability, and create complexity that can impact reliability and security.

Intel Virtualization Technology (Intel VT) addresses these challenges at the silicon level, by providing comprehensive hardware assists that boost virtualization software performance, improve application response times and provide greaterreliability, security and flexibility. These integrated hardware assists accelerate fundamental virtualization processes throughout the platform to reduce latencies and avoid potential bottlenecks. They also reduce the demands placed on the virtualization software, so more processor cycles are available for running business applications. As a result,you can consolidate more applications and heavier workloads per server to get better value from your server and software investments.
