Enhancing FortiGate-VM Performance with DPDK and vNP offloading

DPDK and vNP enhance FortiGate-VM performance by offloading part of packet processing to user space while using a kernel bypass solution within the operating system. You must enable and configure DPDK with FortiOS CLI commands.

FortiOS 6.2.3 supports DPDK for VMware ESXi environments.

The current DPDK+vNP offloading-capable version of FortiOS only supports FortiGate instances with two or more vCPUs. Minimum required RAM sizes differ from those on regular FortiGate-VM models without offloading. Allocating as much RAM size as the licensed limit for maximum performance is recommended, as shown. See the 5.6 document for minimum size reference. FortiOS 6.2.2 and later versions do not restrict RAM size by license. Therefore, you can allocate as much memory as desired on 6.2-based DPDK-enabled FortiGate-VMs:

Model name

RAM size (licensed limit)

FG-VM02(v)

No restriction

FG-VM04(v)

No restriction

FG-VM08(v)

No restriction

FG-VM16(v)

No restriction

FG-VM32(v)

No restriction

You can enable DPDK up to 64 vCPUs.

Note

The current build does not support encrypted traffic. Support is planned for future versions. Disabling the DPDK option using the CLI or adopting regular FortiGate-VM builds when using IPsec and SSL VPN features is recommended.

Note

Enabling DPDK+vNP offloading may result in fewer concurrent sessions when under high load than when DPDK+vNP offloading is not enabled and the same FortiGate-VM license is used.
