S2U King Cobra

100% LRU, Short Rack 2U Server with Router, Managed Switch, Ultra High Speed RAID and Quad GPU

Categories: ,


The S2U “King Cobra” is a major breakthrough in server technology. It is the smallest, fastest rack-mount server on the market, with more I/O performance and storage functionality than any other server. It replaces several 1U/2U servers, switches/routers, RAID controllers, and Auxiliary Power Units (APU) with a single 2U, 17-inch deep (short) rack-mountable (or freestanding) enclosure. Furthermore, 100% of the “King Cobra” electronics modules are Line Replaceable Units (LRU) specifically designed for field replacement and upgrading. This at-the-module 100% LRU functionality allows the user to replace any function of the system in the field within seconds, thus providing ultimate flexibility and minimizing down time.

The S2U features state-of-the-art CPU, packaging, and cooling design, utilizing the rugged and proven OpenVPX (VITA 65) architecture. Unlike PC motherboards, which virtually all servers use, the “King Cobra” OpenVPX design can withstand much higher shock, vibration, and temperatures than standard servers. The “King Cobra” utilizes a modular subsystem design allowing the OEM user to upgrade or change the server’s configuration in the field quickly and economically. This reliable, field-proven OpenVPX architecture also takes full advantage of commercial-off-the shelf (COTS) PCI Express (PCIe) boards such as ultra-high-performance video boards, RAID controllers, GPGPU compute engines, and DSP modules, which may be quickly and easily plugged/unplugged into the system within seconds. OpenVPX is also used for the redundant, N+1 hot-swappable power supply modules.


The S2U is designed to replace up to 8U of space in a rack mount card cage, and is ideal for applications requiring rugged servers with ultra high storage, CPU power with optional best graphics, or backup power for orderly shutdown. The King Cobra provides the highest SWaP efficiency in the server market while providing 100% LRU capability for minimum downtime, all while minimizing the needs for sparing servers. The S2U is targeted for applications where ruggedness, size, power, and serviceability are key factors, such as in airdrop, naval command centers and submarines.

S2U “King Cobra” has unprecedented options for COTS add-in modules, including standards such as PCIe, OpenVPX, XMC and more. For example, two NVIDIA GTX-980 graphics cards can be installed, each with up to 4.62 TFLOPS per GPU. Collectively, this gives S2U HPEC/HPC GPGPU performance up to 9.24 TFLOPS with 4,096 CUDA cores.

The King Cobra supports the most popular Hypervisors offered by VMware®, WindRiver® and Microsoft®, and may be shipped from the factory with operating systems such as Windows® and Linux® pre-installed. The S2U is fully compliant to MIL-STD 810G, MIL-STD-1275D, MIL-S-901D, DO-160D, MIL-STD-461E and IP54 standards.
