  • Application

    Phoenix is a conduction-cooled, Xeon-class, VPX-based “blade” server that is ideal for heavy number-crunching applications where data is brought in via PCI Express Gen 3, 14 port Layer 2/3 managed switch, or optional add-in XMC I/O such as A/D or RF. Running Linux, Windows 10, or Microsoft® Server operating systems, Phoenix is ideal for combat and surveillance vehicles where several computers are used for data collection, targeting/mapping, and data acquisition. The VPXC400 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 VPXC400 is fully compliant to MIL-STD-810G, MIL-S-901D and DO-160D. Phoenix is developed in alignment with the SOSA™ Technical Standard.
  • General Description

    The VPXC400 "Phoenix" is a Xeon-class, VPX-based “blade” server intended for ATR or vetronics chassis. It is a dual slot conduction-cooled 6U OpenVPX module with twelve 1 Gigabit Ethernet ports and two 10 Gigabit Ethernet ports. This module supports a Xeon® E5 processor (E5-26xx v4) up to 18 physical cores with Hyper-Threading for a total of 36 logical cores operating at up to 2.1 GHz with the ability to TurboBoost up to 3.3 GHz. To harvest this incredible CPU performance, the CPU is coupled with up to 512GB of DDR4 RAM organized in four banks. Each RAM bank consists of two DDR4 DIMM arrays with Error Correcting Code (ECC). The ECC RAM provides 2-bit error detection with 1-bit of correction, and supports up to 2133 Mega Transfers per Second (MTS) between CPU and memory.

    Phoenix also provides twelve 1 Gigabit and two 10 Gigabit Ethernet managed switch ports. The Layer 2/3 managed switch silicon and firmware is from Microsemi and has an advanced GUI for configuration such as the creation of VLANs for local packet routing. The switch can omitted as a value-engineering option, although the 10 Gigabit ports remain standard. A separate 1 GbE Service port is also included as a way to configure or remotely query the SBC separate from the managed switch.

    Additionally, there are four USB 2.0 ports, four SATA III ports, four PCIe ports (three x1 and one x16 lanes), a VGA/DVI-D video port, and dual COM ports with RS-232/422/485 provided to the VPXC400 backplane. For custom I/O, the SBC provides one XMC site with x8 Gen 3 PCIe, an optional MXM site for GPU graphics, and an optional M.2 bootable SSD. The SBC provides two Special Application Module (SAM) sites, which support two mSATA SSD devices that may be used to boot the Operating System (OS) with RAID functions. Additional SAM I/O devices such as GPS, MIL-STD-1553, CAN bus, or other PCI Express-Mini cards may be used as well. Other I/O functions of the CPU module include: Trusted Platform Module (TPM), eight GPIO lines, 16 MB BIOS Flash, Real Time Clock (RTC) with field replaceable battery, and voltage/temperature monitoring via I2C bus. The CPU module also provides an incredible 19 lanes of PCIe Gen 3 support for I/O expansion via its VPX P1-P5 connectors.
  • Technology Used

    The Phoenix utilizes the most powerful Xeon® processor from Intel®. The Broadwell-EP CPU is a fourth-generation Nehalem processor with a fully integrated memory controller for the best possible memory performance. This CPU has many added security functions, such as Intel’s second-generation Virtualization Technology VT-x, Trusted Execution Technology (TXT), and Active Management Technology (AMT) for remote KVM functions, and Converged Platform Power Management (CPPM) for thermal management and power saving. The optional graphics engine is based around the most powerful AMD full-size, embedded MXM GPU module for outstanding performance in 2D and 3D processing and is fully virtualized.
  • Cooling

    The Phoenix is equipped with GMS' patent pending RuggedCool™ technology, which is the most unique cooling system in the industry yielding the only server “blade” that can operate up to -40°C to +85°C at full load! This cooling approach provides the lowest thermal resistance to the VPX chassis while providing the highest shock specifications known in the industry. In addition, the VPXC400 is furnished with a GMS-designed wedge lock that provides over 8x more surface area for increased heat transfer compared to standard wedge lock designs. In-PCB core card cooling thermal layers plus top-side milled heat sinks are directly extended to the GMS wedgelock’s much larger fixed center section, providing an enhanced thermal path straight to the chassis side rails/slots.
