  • Application

    The Python is designed to be a fully ruggedized server with standard commercial interconnects on the rear panel and expansion for up to two half-size, 8-lane PCIe I/O cards. It is ideal for server racks where a sealed fan-less server is needed for data collection, targeting/mapping, and data acquisition. The SO301 supports the most popular Hypervisors offered by VMware®, WindRiver® and Microsoft® and may be shipped from the factory with operating systems such as Windows®, Linux® and/or VMware® pre-installed. The SO301 is CE Mark and FCC compliant with an optional support for MIL-STD-1275.
  • General Description

    The SO301 "Python" is a second-generation fully rugged server utilizing commercial PC interconnects with two standard PCI Express expansion sites. It is designed to provide the highest level of server class performance possible in a fully ruggedized, conduction-cooled system operating over a full -20°C to +75°C temperature (0°C to +55°C Standard).  The Python is targeted for applications where an ultra-fast, multi-core CPU is needed with vast amounts of high-speed, ECC-protected RAM to support commercial off-the-shelf I/O modules in half-size PCI Express formats. The SO301 supports 10 physical CPU cores with Hyper-Threading for a total of 20 logical cores, each operating up to 2.4GHz with the ability to TurboBoost up to 3.0GHz. To harvest this incredible CPU performance, the CPU is coupled with up to 128GB of DDR3 RAM organized in four banks. Each RAM bank consists of two DDR3 DIMM arrays with Error Correcting Code (ECC). The ECC RAM provides 2-bit error detection with 1-bit correction and supports up to 1600 Mega Transfers per Second (MTS) between CPU and memory. 
    The I/O subsystem for the Python is designed to support a wide array of high-speed I/O devices with modularity and security. The I/O consists of a host CPU I/O and two 8-lane commercial, half-size PCIe I/O expansion sites. The host CPU supports dual 10Gigabit Ethernet ports, four USB 3.0 and two USB 2.0 ports with power, two Serial ports with RS-232/422/485 buffers, full HD-Audio and eight General Purpose I/O lines. There is also 8-lane PCIe to support a powerful MXM GPU with two Display Port/HD Video ports and one VGA port (Optional). The SO301 also provides a very flexible set of storage devices with highly secure options. The Python supports up to four removable 2.5” SATA SSD drives with an optional AES-256 Encryption, and secure erase functions up to 2TB.  Additionally, the host supports one mSATA drive with write-protect for use as a local boot device up to 1TB. Other optional I/O devices included for the host CPU are two SAM™ sites for user I/O like GPS for accurate positioning and time stamping of data packets, Wi-Fi/ Bluetooth, and many other I/O functions. The SO301 also features an optional Baseboard Management Controller (BMC) for detailed system health monitoring and reporting using industry standard IPMI 2.0 via a dedicated Ethernet port or Serial Port. The two PCIe expansion sites support all commercial half-size PCIe cards with standard I/O interconnects to the rear panel. All the I/O ports utilize commercial connectors for easy, economical cabling.
  • Technology Used

    The Python utilizes the most powerful Xeon® processor from Intel®. The Ivy Bridge-EP CPU is a second-generation, 10-core Sandy Bridge microarchitecture processor with a fully integrated memory controller for the best possible memory performance. This CPU is the highest performance server-class CPU from Intel® with many added security functions, such as Intel’s second-generation Virtualization Technology VT-x, Trusted Execution Technology (TXT), and Converged Platform Power Management (CPPM) for thermal management and power saving. The graphics engine is based around the most powerful AMD® full-size embedded MXM GPU module for outstanding performance in 2D and 3D accelerations and can be fully virtualized. The I/O is provided via 40 lanes of PCIe 3.0 which are monitored via the Trusted Platform Module (TPM) to assure full security and safe operation.
  • Cooling

    The Python is equipped with GMS' patent pending RuggedCool™ technology, which is the most unique cooling system in the industry and is the only rugged server that operates up to -20°C to +75°C at full load! This cooling approach provides the lowest thermal resistance to the case while providing the highest shock specifications known in the industry. The SO301 is a fan-less system for reliable operation and can be mounted directly to a metal surface or used as a stand-alone system.
