The 7121F is built for large enterprises, service providers, and organizations pushing high volumes of traffic through a data center core or enterprise edge. If your environment needs sustained NGFW throughput above 500 Gbps, hardware-accelerated SSL inspection at scale, or internal segmentation across a carrier-grade infrastructure, the 7121F is sized for that job. Smaller branch or midsize campus deployments are better served by the FortiGate 100F through 600F families.

The 7121F delivers up to 1.89 Tbps of IPv4 firewall throughput, 675 Gbps of IPS throughput, 550 Gbps of NGFW throughput, and 520 Gbps of full threat protection. SSL inspection runs at 540 Gbps. These figures represent the fully-configured chassis with all FIM and FPM modules installed. Performance varies depending on module count and traffic profile.

The 7121F uses Fortinet's NP7 network processors and CP9 content processors. NP7 chips in the FIM interface modules handle session-aware load balancing and distribute traffic across the FPM processor modules over a 1 Tbps fabric backplane. CP9 processors in the FPMs accelerate IPS, SSL decryption, and antivirus scanning. This dedicated silicon lets the chassis hit Tbps-level firewall rates without bottlenecking on general-purpose CPUs.

The FG-7121F is a 16U, 19-inch rackmount chassis with 12 slots. Slots 1 and 2 hold the FIM interface modules and slots 3 through 12 accept up to ten FPM processor modules. Two redundant system management modules control power and cooling. Eight hot-swappable PSUs provide power redundancy. Generation 2 ships with 2500W PSUs and Generation 1 ships with 2000W PSUs. Both generations run the same FortiOS software feature set.

Yes. The 7121F supports both Active-Active and Active-Passive high availability. Redundant system management modules, hot-swappable power supplies, and swappable fan modules reduce hardware single points of failure. FortiOS handles session synchronization and failover at the software level so traffic stays moving during a switchover. The redundant SMMs are always accessible via their MGMT interfaces regardless of which one is active.

The 7121F supports the full FortiGuard Labs service stack, including intrusion prevention (IPS), application control, web filtering, DNS filtering, antivirus, and sandboxing. FortiGuard Labs pushes threat intelligence updates continuously from its AI-powered research operation. Services are purchased separately from hardware as 1, 3, or 5 year subscriptions. Our team quotes hardware and FortiGuard licensing together so you know the full cost before the purchase order is issued.
