Thunder is an ideal forwardly-deployed vehicle-mounted battlefield/airborne/shipboard server/switch/router/NAS/artificial intelligence computer that offers the highest density of computing power in the smallest fully-sealed, rugged package. When equipped with the router or intelligent Layer 2/3/4 Ethernet switch, Thunder becomes a rugged compact server, with a dedicated switch or router capabilities to offer maximum network flexibility.

Networking is handled through four 40 GbE ports and thirty 10 GbE ports. The 10 GbE ports can be configured with a Broadcom® Layer 2/3/4 enterprise class switch (SW) or as segregated and secure port connections each with their own subnet mask to avoid data crossover (RT). In the RT every Ethernet port is directly coupled to the CPU, an architecture that is ideal for secure communications or dedicated hypervisor/virtual environments.

Network routing technology includes software-defined networking (SDN) on various operating systems and virtual machine (VM) hypervisor environments. Each of the 10 GbE ports support power-over-Ethernet (PoE+) to directly power remote nodes while simplifying wiring requirements, up to 310 W maximum total power sourced.

Integrated support is available for a lower power commercial General-Purpose Graphics Processing Unit (GPGPU), full size and height, for applications where large data processing tasks are required. The integrated GPGPU can “link” with other external GPGPUs, such as GMS’s companion X422 Co-Processor, via the PCIe 3.0 bus expansion feature. This bus expansion provides flexibility to upscale computing resources to match application computing requirements.
