SriovNetworkNodePolicy

The SriovNetworkNodePolicy resource allows you to connect containers directly to network equipment. The “SriovNetworkNodePolicy” object is associated with the “SriovNetwork” object. Both entities together provide complete host-level control of SR-IOV network settings.

To add a new resource on the SriovNetworkNodePolicy page of the Networks section, click “+ Add SriovNetworkNodePolicy”. The created resources will appear in the list of items.

All SR-IOV resources must be installed in the same namespace where SRIOV-Operator is installed. In this case, the kube-system namespace will be applied automatically.

Detailed description of the parameters of the SriovNetworkNodePolicy object #

• Title;
• ResourceName: associates the network policy (SriovNetworkNodePolicy) with the network (SriovNetwork);
• Node selector: Determine which nodes are covered by the SR-IOV policy using node labels. Please note! The label selector works on the principle of union. The selected object must have all of the specified labels.
• Priority: priority for applying the SR-IOV policy. If a node has multiple policies, they are applied according to priority.
• deviceTypes: driver type for created VFs. Possible values:
  • “netdevice (driver in the Linux kernel)”;
  • “vfio-pci” (driver for DPDK).
• mtu: The MTU (Maximum Transmission Unit) value for devices determines the maximum size of a data packet that can be transmitted through the network interface.
• nicSelector: filters for selecting NIC (Network Interface Cards) policies. May include subsets based on Vendor ID, Device ID, Root Device ID, and PfNames.

• numVfs: The number of virtual functions that should be configured on each NIC.
• linkType: network connection type. Possible values:
  • “Eth”: describes the Ethernet connection;
  • “IB”: describes the InfiniBand connection;
• eSwitchMode: operating mode of the virtual switch (eSwitch). Possible values:
  • “legacy”: describes the mode of a virtual switch based on a legacy driver;
  • “switchdev”: describes a virtual switch mode that offers increased performance and lower latency compared to traditional software switching.
• isRdma: a flag that indicates whether RDMA (Remote Direct Memory Access) is supported.
