For more specific performance optimization recommendations, please refer to Cisco® BIOS best practices tuning guides and Cisco Validated Designs for specific workloads. Hyper-V Best Practices (Configuration, Networking & Security). This option is prone to misconfiguration and can cause reduced network performance when enabled. Back then it was best practice to have one Physical NIC set up for a cluster network, one Physical NIC set up for a heartbeat network, then one Physical NIC set up for the Host MGMT connection, then team the rest for virtual Switch and storage network. In best practice you should be using LBFO (nic teaming) and base your total VM count on the available VMQ/RSS queues available on your NIC’s and the expected network load/traffic. A physical host can have Hyper-V enabled and still use RSS. In the Settings window, under the relevant network adapter, select "Hardware Acceleration". Create a separate virtual switch for each type of traffic. There’s an in-depth article on the Hyper-V Virtual Switch on this blog, but for the sake of this article I’ll give you a basic introduction to the concept, within the bigger picture. The other 4 are for guest traffic. This feature is a silicon-level implementation that works in conjunction with hardware support and includes the intelligence for multiple queue formation (as supported by the specific adapter) and the sorting of packets in the physical NIC. I checked the current MPIO and Hyper-V documentation, and did not find these shown. VMMQ distributes network traffic across multiple queues and CPU cores within each VM, enabling even higher network throughput and lower latency compared to VMQ.
