Configure host boot options

Restrictions and guidelines

To enable DPDK on a host, you must configure the boot options for the host as follows:

• Enable HugePage. As a best practice, set the HugePage size to 1 GB.

• Enable IOMMU.

• To achieve the best performance, specify multiple isolated CPUs for DPDK for a minimum of one NUMA node. If hyper-threading is enabled, you must isolate CPUs for hyper-threading and reserve some CPU resources for system processing. As a best practice, do not configure the UIS-Sec gateway VM or DPDK to use CPU 0.

8. Enable CPU isolation. Click the Edit icon for each NUMA node, and select two CPUs for DPDK.

As a best practice, do not select CPU 0 for UIS-Sec gateway VM or DPDK.
