The 1U rack-mount S1U401-MD multi-domain Cyclone is two complete (up to) 18 core Xeon® server sub-systems packaged together but electrically isolated, including their separate power supplies. Cyclone is intended for military/defense/aerospace Red/Black networks—such as found on platforms with SIPR/NIPR networks. With the onboard 1 and 10 Gigabit Ethernet ports, Cyclone is an ideal forwardly-deployed vehicle-mounted battlefield dual-server that offers double performance or redundancy due to the dual domains. Alternatively, the S1U401-MD is an ideal airborne network multi-domain server that can also drive operator consoles, such as in an ELINT platform, while recording data and distributing it to multiple Ethernet LANs. Optional Ethernet ports provide LAN connectivity, CPU-based bridging, and multi-node connectivity. Removable drives with optional encryption provide NAS and software-defined storage that scales with system requirements.

Cyclone can also be used in industrial and commercial platforms since it has server-class performance, exceptional I/O capabilities and removable storage. The S1U401-MDSW is fully compliant to MIL-STD-810G, MIL-STD-1275D, MIL-S-901D, DO-160D and MIL-STD-461E. This system may also be ordered from the factory with operating systems such as Windows® or Linux® pre-installed.

General Description

The S1U401-MD “Cyclone” is an ultra-rugged, 1U rack mount, lightweight multi-domain server system with two domains, each with up to 16 CPU cores, dual 10 Gigabit Ethernet ports, removable drives and exceptional I/O flexibility. It is designed to provide two fully-independent and isolated high-performance Intel® Xeon® E5 v4 servers, as well as two sets of four removable SAS/SATA/NVMe drives—all in a 1U high box. It provides the highest level of workstation performance possible in a fully ruggedized, convection-cooled system, operating from -20° C to +75° C. Even the AC or DC power supplies are separate to assure full isolation. This system architecture simplifies deployable MIL-SPEC technology for Multiple Independent Levels of Security (MILS), NSA Red/Black network separation, or system redundancy, while integrating processing, storage and high speed I/O in a small, ultra-rugged 1U high rack-mount enclosure with the greatest possible performance per dollar and per watt.

The S1U401-MD contains two system domains in one box: a Red domain and a Black domain. Each domain supports the latest, most power-efficient Intel® Xeon® E5 with Hyper-Threading for a total of up to 18 physical cores (36 logical cores) operating up to 2.1 GHz and having the ability to Turbo Boost up to 3.3 GHz. To harvest this incredible CPU performance, the CPU is coupled with up to 256 GB of DDR4 RAM organized in four banks with ECC support (2-bit error detection and 1-bit error correction). All these Xeon® cores coupled with Cyclone’s I/O can be used to create multiple virtual machines (VMs) allowing each domain to replace up to 36 separate single-processor systems. As a system, S1U401-MD provides up to 72 virtual machines in only 1U. In addition, each domain contains its own independent dual port 10 Gigabit Ethernet I/O in only 1U of rack mount space. Add-on networking modules can bring two more 40 Gigabit Ethernet ports (or four 10 Gigabit ports) and twelve 1 Gigabit Ethernet ports per each domain.

Cyclone also offers the most secure storage subsystem possible. It supports up to 16 MB BIOS Flash with hardware-write protect and secure erase. The onboard fixed M.2 boot device and (up to four) removable 2.5” SAS/SATA/NVMe (PCIe) SSD drive(s) provides optional hardware write-protect, secure erase and encryption functions. The S1U401-MD can optionally support FIPS-140-2 and FIPS-197 encryption standards for ultra-secure data storage. These data security functions, along with the Trusted Platform Module (TPM) 2.0 and Intel’s Trusted Execution Technology (TXT), make the Cyclone the smallest and most secure multi-domain system on the market.

On Cyclone, General Micro Systems has used PCI Express Gen 3 extensively as the backbone of the S1U401-MD system. The I/O subsystem for each of the two Cyclone domains is designed to accommodate a wide array of standard I/O functions. Each S1U401-MD domain supports two 10 Gigabit Ethernet ports (copper) as standard, plus optional 12 Gigabit Ethernet ports with PoE+ up to 150 W total, and dual 40/quad 10 Gigabit Ethernet ports (fiber). Cyclone includes provisions for optional software routing capability on the 1 and 40 Gigabit ports using CPU-hosted Cisco® or Juniper Networks® enterprise software.

Additional standard I/O includes: four USB 3.0 ports, a 1 Gigabit service Ethernet port and high-definition HDMI/DVI-I console video (no audio). Cyclone can also be equipped with high-performance graphics from either AMD® or Nvidia® driving dual displays via HDMI/DP/DVI. Using a GMS SAM I/O™ PCI-Mini add-in module, SMPTE HD-SDI long-reach video can be added and connected to panel-mounted BNC connectors.

Cyclone, at its core, is a very high performance rack-mount server with processing, networking, and storage. But in defense applications, program-specific I/O—whether legacy or future I/O—is a critical requirement. Cyclone handles this with no fewer than six different add-in choices. There are the two standard SAM I/O™ modules with an additional Management Plane module containing a third SAM I/O™ site. The optional M.2 boot SSD can be replaced with an M.2 I/O. The add-in GPU module can be replaced with any GMS-qualified standard full-size, half-height (low profile) x8 PCIe card. Finally, the Ethernet expansion module can be replaced with a custom I/O function such as an LTE/Wi-Fi modem, DSP or FPGA co-processor, or other high-speed A/D/A front end.

Technology Used

The Cyclone utilizes the latest Intel® Xeon® E5 CPU which is ideal for servers. Each of the two separate domains boasts up to 18 cores/36 threads and advanced thermal management. The Xeon® E5 supports Hyper-Threading for a total of 36 logical cores per domain. The processor clocks up to 2.1 GHz per core with Turbo Boosting up to 3.3 GHz. On Cyclone, each Xeon E5 CPU also supports 256 GB of DDR4 RAM with ECC.

Xeon® E5 server class processors have RAS features like PCIe hot-plug and CMCI, along with security functions such as Intel’s second-generation Virtualization Technology VT-x and Trusted Execution Technology (TXT). The CPU platform supports PCI Express Gen 3, USB 3.0 and SATA 3 for the highest performance possible on a server platform. On Cyclone, General Micro Systems has used PCI Express Gen 3 extensively as the backbone of the S1U401-MD system.

Full Environmental Specs

In air-cooled configuration, S1U401-MD uses a combination of thermal techniques to achieve temperature reliability and high system MTBF with redundancy. Firstly, Cyclone uses General Micro Systems’ patent-pending RuggedCool™ technology to conductively cool the processors. Also, GMS’ TwoCool® convection system uses three internal fans that act as a multi-redundant thermal system with intelligent fan control (or optional BMC-based control), providing high confidence and high MTBF. Should one fan fail, the others can contain operational temperature for a period of time sufficient to shut down the system. Each domain contains its own set of three system fans.

The Cyclone is available in ruggedization levels R1-R3. Additional information regarding the ruggedization levels and full environmental specifications for this product can be found on our website at www.gms4sbc.com/technologies/ruggedization.
