Which one fits
Stepping up from the FortiGate 7081F-DC to the FortiGate 7121F-2-DC moves threat-protection throughput from 312 Gbps to 520 Gbps (1.7×), IPS throughput from 405 Gbps to 675 Gbps (1.7×) and NGFW throughput from 330 Gbps to 550 Gbps (1.7×). Neither choice moves SSL-VPN throughput (13.5 Gbps against 13.7 Gbps) or raw firewall throughput (both 1.89 / 1.88 / 1.129 Tbps), so a site held back by remote-access capacity gains nothing from the FG-7121F-2-DC.
Choose the FortiGate 7081F-DC if
- Threat-protection throughput is already enough at 312 Gbps: the FG-7121F-2-DC adds 1.7× you will not use.
- Your limit is remote-access capacity, which the step up does not move: 13.5 Gbps against 13.7 Gbps.
- Form Factor: Rack Mount, 12 RU - 8-slot chassis, where the FG-7121F-2-DC is Rack Mount, 16 RU - 10 slots for FPM and 2 slots for FIM.
Choose the FortiGate 7121F-2-DC if
- Threat-protection throughput has to go past 312 Gbps: the FG-7121F-2-DC publishes 520 Gbps.
- IPS throughput has to go past 405 Gbps: the FG-7121F-2-DC publishes 675 Gbps.
- NGFW throughput has to go past 330 Gbps: the FG-7121F-2-DC publishes 550 Gbps.
- Form Factor: Rack Mount, 16 RU - 10 slots for FPM and 2 slots for FIM, where the FG-7081F-DC is Rack Mount, 12 RU - 8-slot chassis.
21 of the 49 published rows are identical — Trusted Platform Module at Yes, Concurrent SSL-VPN Users at 30,000, Virtual Domains at 10 / 500 and Firewall Policies at 200,000 among them — so the choice does not touch any of those.
