SRX3400 Services Gateway Component Basics
This section describes the card form factors, the services gateway components available,
and where they can be installed in the SRX3400 Services Gateway. It also describes the
flow of data through the services gateway. This section includes the following topics:

SRX3400 Services Gateway CFMs
The services gateway chassis supports common form-factor modules (CFMs). A
single-wide module format and a double-wide module format are available. I/O card
(IOC), Services Processing Card (SPC), and Network Processing Card (NPC) modules
are in single-wide CFM format. The Switch Fabric Board (SFB), Routing Engine, and SRX
Clustering Module (SCM) are not in CFM format, and thus have assigned slots within the
chassis. With the interchangeability among the IOCs, SPCs, and NPCs, you have more
flexibility and scalability when deploying your networks based on the requirements in
the field. For example, if you need more ports and bigger oversubscription ratio, then you
can load more slots with IOCs; on the other hand, if you need smaller oversubscription
ratio for better QoS behavior, or you need more security services, then you can load more
slots with SPCs and only use the on-board network interface ports.
