The CAR-6028 is targeted for firewall solutions and unified threat management (UTM) but can also be used by network and service providers for a backup solution. The CAR-6028 by standard already offers eight Gigabit- Ethernet RJ45 ports but also has two frontloading slots for network adapters using the manufacturer's own designed network configuration. These proprietaries (NIP) modules each provide up to eight, extra high-speed Ethernet ports. To add networking flexibility and throughput, the CAR-6028 provides an internal PCI Express 4.0 x8 slot that enables the configuration with an FPGA card like the Intel FPGA Programmable Acceleration Card N3000, to maximize versatility in communication infrastructures by supporting the main system processor with its customization possibilities and full programmability, for many different and maybe, even yet unknown, network protocols.
