Intel® Directed I/O Virtualization Technology (VT-d)
Intel® Directed I/O Virtualization Technology (VT-d) continues the existing support for virtualization solutions for IA-32 (VT-x) and Itanium® processor systems (VT-i) and expands it with new support for I/O device virtualization. Intel VT-d can help users improve the security and reliability of systems as well as the performance of I/O devices in virtualized environments.

Intel® Virtualization Technology (VT-x)
With Intel® Virtualization Technology (VT-x), a hardware platform can be utilized as multiple "virtual" platforms. It provides enhanced manageability through reduced downtime and maintains productivity by shifting computing tasks into separate partitions.

Intel® 64
In conjunction with the appropriate software, the Intel® 64 architecture enables 64-bit processing on servers.
