Abstract: The purpose of this project is to describe the steps needed to enable the Single Root Input Output Virtualization (SR-IOV) feature on Network Interface Cards (NICs) and validate the performance advantage provided by Microsoft® Windows® Server 2012 Hyper-V® on IBM® Flex System® x240 compute nodes. Through embedded 10GbE Virtual Fabric Adapter (VFA) II cards, data packets were generated and sent from one compute node to virtual machines that were hosted by the other node. The performance was evaluated based on the network throughput and processor usage on the virtual machines and the Hyper-V host server.
The test results show that, when the SR-IOV functionality is enabled:
• The network throughput on virtual machines is increased by up to 33%. The actual values vary, depending on the virtual server density on the host.
• Hyper-V host server’s processor utilization is reduced by up to 40%.
