Achieving Fast, Scalable I/O for Virtualized Servers: With Intel Virtualization Technology and the PCI-SIG Single Root I/O Virtualization and Sharing Specification

IT organizations are taking advantage of virtualization to consolidate server infrastructure, reduce power, cooling and management costs, and provide simpler and more affordable solutions for high availability, load balancing and disaster recovery. Servers based on multi-core Intel Xeon processors with Intel Virtualization Technology (Intel VT) help to magnify the benefits of virtualization, by enabling higher consolidation ratios and better application performance. Recent enhancements to Intel VT are directed at solving the next virtualization challenge: delivering fast and scalable I/O bandwidth for virtualized servers.
