DPDK support on AWS native AMI SE

NSX Advanced Load Balancer supports DPDK on AWS native AMI SE is available at the SE level.

The following options are available under the SE Group boot-up properties for the DPDK support:

• se_dpdk_pmd: This configuration knob enables the DPDK mode when the value of the se_dpdk_pmd parameter is set to 1.

• max_queues_per_vnic: The max_queues_per_vnic parameter in SE-group properties allows configuring the maximum number of queues per dispatcher.

Note:

• DPDK is disabled by default.

• DPDK is supported on AWS instances that support the Elastic Network Adapter (ENA). For detailed information on the max_queues_per_vnic option, see the Multiple Queues per Dispatcher topic in the VMware NSX Advanced Load Balancer Configuration Guide.

• The DPDK is enabled by default if the instance type supports ENA.

• For the Controller migrated from any version < 20.1.1 to 20.1.1, DPDK is disabled. This is because it is a change in behaviour for the Controllers with respect to the performance numbers. But, for new SE group ENA-supported instances, DPDK will be enabled by default, and if the instance does not support ENA, the SE group switches automatically to PCAP mode. The se_dpdk_pmd in SE group will be 0, which is auto mode, for all new SE group.
