Chapter 8 Hardware Acceleration : FortiGate NP4 architectures : FortiGate-3240C
  
FortiGate-3240C
The FortiGate-3240C features two NP4 processors:
The 10Gb interfaces, port1 through port6, and the 1Gb interfaces, port13 through port20, share connections to one NP4 processor.
The 10Gb interfaces, port7 through port12, and the 1Gb interfaces, port21 through port28, share connections to the other NP4 processor.
In addition to the ports being divided between the two NP4 processors, they are further divided between the two connections to each processor. Each NP4 can process 20 Gb of network traffic per second and each of two connections to each NP4 can move 10Gb of data to the processor per second, so the ideal configuration would have no more than 10 Gb of network traffic to each connection of each NP4 at any time.
