Intel® Ethernet and Configuring Single Root I/O Virtualization (SR-IOV) on Microsoft* Windows* Server 2012 Hyper-V

Intel® Ethernet and Configuring SR-IOV on Windows* Server

The Intel® Ethernet Converged Network Adapter and Intel® Ethernet Server Adapter family of adapters introduced numerous industry-leading features that are helping data center administrators implement innovative solutions for difficult and challenging connectivity problems. I/O virtualization is one of the fastest growing usage models within the data center.

Deploying IO Virtualization in Microsoft Windows Server 2012* with Hyper-V*
Many of the 10Gb Converged Network Adapters and 1Gb Server Adapters that are based on Intel® Ethernet Controllers include Intel® Virtualization Technology (Intel® VT) for Connectivity (Intel® VT-c) which is a collection of I/O virtualization technologies that enable lower CPU utilization, reduced system latency, and improved networking throughput. Intel® VT-c is one of the key component technologies of Intel® Virtualization Technology that have been included as part of the Microsoft Windows Server 2012 Hyper-V.

Virtual Machine Device Queues (VMDQ) provide hardware assists to the hypervisor that improves 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 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 and sharing (SR-IOV) support allows multiple virtual machines to bypass the hypervisor networking stack and talk directly to unique resources on Intel® Ethernet Converged Network Adapters. The PCI-SIG SR-IOV standard offers an advanced, nonproprietary approach to providing I/O resources directly to virtual machines that helps significantly reduce latency, reduce CPU utilization and increase throughput.
