Putting Server Virtualization to Work
enterprises have been using virtualization technology on mainframes and RISC-based systems
for years to enable better utilization of hardware resources. As x86 servers have become a mainstay
in the enterprise, more companies are exploring virtualization with these servers to enable more
productive, flexible, and scalable datacenters while reducing costs and boosting data availability.
Computing technologies from AMD are providing the foundation for today’s — and tomorrow’s —
