Intel® Virtualization Technology for Connectivity
Optimizing virtualized I/O for balanced server performance
Intel® Virtualization Technology (Intel® VT) for Connectivity (Intel® VT-c) enables lower CPU utilization, reduced system latency, and improved networking throughput. Intel® VT-c is one of the key component technologies of Intel® Virtualization Technology.
Virtual Machine Device Queues (VMDQ) improve traffic management within the server by offloading traffic sorting and routing from the hypervisor’s virtual switch to the Intel® Ethernet Controller. Working in conjunction with VMware NetQueue* or Microsoft Virtual Machine Queues*, VMDQ enables traffic steering and balanced bandwidth allocation across the Intel Ethernet Controller’s multiple hardware queues.
PCI-SIG Single Root I/O Virtualization (SR-IOV) allows partitioning of a single Intel® Ethernet Server Adapter port into multiple virtual functions. IT administrators can use these virtual ports to create multiple isolated connections to virtual machines.
