Chapter 8 Hardware Acceleration : Hardware acceleration overview : Security processors (SPs)
  
Security processors (SPs)
FortiGate Security Processing (SP) modules, such as the SP3 but also including the XG2, XE2, FE8, and CE4, work at both the interface and system level to increase overall system performance by accelerating specialized security processing. You can configure the SP to favor IPS over firewall processing in hostile high-traffic environments. The following security processors are available:
The SP3 is built into the FortiGate-5101B and provides IPS acceleration. No special configuration is required. All IPS traffic is accelerated by the built-in SP3 processors.
The FMC-XG2 is an FMC module with two 10Gb/s SPF+ interfaces that can be used on FortiGate-3950B and FortiGate-3951B units.
The FortiGate-3140B also contains a built-in XG2 using ports 19 and 20.
The ADM-XE2 is a dual-width AMC module with two 10Gb/s interfaces that can be used on FortiGate-3810A and FortiGate-5001A-DW systems.
The ADM-FE8 is a dual-width AMC module with eight 1Gb/s interfaces that can be used with the FortiGate-3810A.
The ASM-CE4 is a single-width AMC module with four 10/100/1000 Mb/s interfaces that can be used on FortiGate-3016B and FortiGate-3810A units.
