19 # Deploying DPDK requires enabling hugepages for the overcloud compute nodes.
20 # It also requires enabling IOMMU when using the VFIO (vfio-pci) OvsDpdkDriverType.
21 # This should be done by configuring parameters via host-config-and-reboot.yaml environment file.
23 ## Attempting to deploy DPDK without appropriate values for the below parameters may lead to unstable deployments
24 ## due to CPU contention of DPDK PMD threads.
25 ## It is highly recommended to to enable isolcpus (via KernelArgs) on compute overcloud nodes and set the following parameters:
26 #OvsDpdkSocketMemory: "" # Sets the amount of hugepage memory to assign per NUMA node.
27 # It is recommended to use the socket closest to the PCIe slot used for the
28 # desired DPDK NIC. Format should be comma separated per socket string such as:
29 # "<socket 0 mem MB>,<socket 1 mem MB>", for example: "1024,0".
30 #OvsPmdCoreList: "" # List or range of CPU cores for PMD threads to be pinned to. Note, NIC
31 # location to cores on socket, number of hyper-threaded logical cores, and
32 # desired number of PMD threads can all play a role in configuring this setting.
33 # These cores should be on the same socket where OvsDpdkSocketMemory is assigned.
34 # If using hyperthreading then specify both logical cores that would equal the
35 # physical core. Also, specifying more than one core will trigger multiple PMD
36 # threads to be spawned, which may improve dataplane performance.
37 #NovaVcpuPinSet: "" # Cores to pin Nova instances to. For maximum performance, select cores
38 # on the same NUMA node(s) selected for previous settings.
