GCP DPDK support
You can now enable DPDK on FortiGate-VMs deployed on the Google Cloud Platform (GCP). DPDK allows improved network performance.
The following example enables DPDK on a FortiGate-VM deployed on GCP, passes UDP and TCP traffic with an antivirus (AV)/IPS/application firewall policy enabled, then checks the engine and vNP statistics.
To enable DPDK on a FortiGate-VM deployed on GCP:
- In the FortiOS CLI, enable DPDK, reboot, then check the DPDK status:
config dpdk global (global) # set status enable (global) # get status : enable interface : multiqueue : disable sleep-on-idle : disable elasticbuffer : disable per-session-accounting: traffic-log-only ipsec-offload : disable hugepage-percentage : 30 mbufpool-percentage : 25 (global) # set interface port1 port2 port3 port4 (global) # set multiqueue enable (global) # set sleep-on-idle enable (global) # set elasticbuffer enable (global) # end status, interface change will trigger system reboot and will take effect after the reboot. Enabling DPDK will adjust Tx/Rx ring size to max allowable value by PMD for the best performance. Do you want to continue? (y/n)y config dpdk global set status enable set interface "port1" "port2" "port3" "port4" set multiqueue enable set sleep-on-idle enable set elasticbuffer enable set per-session-accounting traffic-log-only set ipsec-offload disable set hugepage-percentage 30 set mbufpool-percentage 25 end
- Check early initialization logs:
