Freescale i.MX6 Based Server Systems – Cornfed CONSERVER and Ventana Network Processing Boards

I usually spend most of my time writing about low cost hardware in this blog, but in this post, I’ll deal with higher-end and more expensive devices based on Freescale i.MX6 with Cornfed CONSERVER Server System and corresponding CONSERVER motherboard, as well as Ventana Network Processing Boards.


Conserver is a low power high-performance ARM processor server system based on Freescale i.MX6 with 4GB RAM, Gigabit Ethernet, and SATA.

Cornfed_CONSERVERThe hardware specifications are as follows:

  • SoC – Freescale i.MX6Q Quad Core ARM Cortex A9 processor @ 1.2 GHz
  • System Memory – 4 GB DDR3 RAM
  • Storage – ?? GB NAND Flash + 1x SATA2 connector for HDD/SSD
  • Connectivity – 1x Gb Ethernet port
  • USB – 4x USB Host ports
  • Video Output – 1x HDMI port
  • Misc – RS-232 Serial port
  • Power Supply – 35W Internal AC Power Supply
  • Dimensions – Mini-ITX form factor

The system is preloaded with Ubuntu, and can be customized with wireless connectivity, or DC power supply, and mounted via DIN rail or Vesa mounting system.

You may think “This is the system I’ve been waiting for!”, until you actually have to pay the bill, as CONSERVER server system costs $649. If you only need the motherboard, you can get it for $449. There’s also just a 30-day warranty… [Update: The price has been lowered to $579 for a full system with 4 GB DDR3 and a 1 TB 7200 RPM hard drive, the motherboard is now available for $349 with power supply, and warranty has been extended to 60 days].

Ventana Network Processing Boards

Ventana network processing boards by Gateworks Corp are a bit different as they offer one or more Gigabit Ethernet ports, mini PCie slots, and they are industrial grade boards. All the six SBC computers for network processing are based on Freescale i.MX6 processors, but the low-end model starts with a dual-core processor @ 800MHz with one mini-PCIe slot, and the best performing model features a quad-core processor @ 1GHz board with 6 mini-PCIe slots, and high definition video support.

The six boards can be differentiated as follows:

  • GW5100 – i.MX6 Dual @ 800MHz, 512MB RAM (default), 1x GbE, 1x Mini-PCIe, 35 x 100mm
  • GW5200 – i.MX6 Dual @ 800MHz, 512MB RAM (default), 1x GbE, 1x mSATA, 2x Mini-PCIe, 70 x 100mm
  • GW5300 – i.MX6 Quad @ 1GHz, 1GB RAM (default), 1x GbE, 1x mSATA, 4x mini-PCIe, 105 x 100mm
  • GW5310 – Same as GW5300 but without video/audio support
  • GW5400 – i.MX6 Quad @ 1GHz, 1GB RAM (default), 1x GbE, 1x mSATA, 6x mini-PCIe, 140 x 100mm
  • GW5410 – Same as GW5410 but without video/audio support

and they share the following specifications:

  • SoC- Freescale i.MX6 Dual @ 800MHz, or i.MX6 Quad @ 1GHz
  • System Memory – 512 MB to 2GB (GW5100 and GW5200) or 4GB (for Others boards)
  • Storage – 256 MB Flash upgradeable to 2GB (all) + mSATA and microSD card slot (except GW5100)
  • Cellular Support – Built-in modem for GW5100, 1x SIM Socket for GW5200, 2x for GW53x0, and 3x for GW54x0
  • Mini-PCIe slots – 1x for GW5100, 2x for  GW5200, 4x for GW53x0, 6x for GW54x0. More with expansion board.
  • Connectivity – 1 to 2 Gb Ethernet ports. More with expansion board.
  • Video/Audio ports – HDMI out, CVBS in (All models), GW5200 adds LVDS out and mic/speaker, GW53x0 boards add HDMI in and CVBS out on top of that, and GW54x0 boards also support component output.
  • I/O ports:
    • Serial – TTL, RS232 and RS485 (exact configuration depends on model)
    • Digital I/O
    • USB – 1x OTG (all) + 1x USB Host on GW5300 and greater
  • Misc – RTC with battery,  voltage & temperature monitor; 3D accelerometer/magnetometer (except for GW5100), optional GPS receiver, PoE support, etc…
  • Power Supply – 8 to 42V for GW5100, 8 to 60V for others.
  • Typical power consumption – 2 to 5 Watts depending on model
  • Operating Temperature – -40 to +85C

The company provides OpenWrt and OpenEmbedded Linux Board Support Packages (BSP) for the boards.

If you feel you don’t have enough ports such as mini-PCIe slots or Ethernet ports, the company provides the following expansion modules:

  • GW16081 Mini-PCIe Expansion Module – 7x Mini-PCIe. LinuxGizmos reports 3x boards can be stacked to get 24x extra Mini-PCIe slots
  • GW16082 Mini-PCI Expansion Module – 4x Mini-PCI
  • GW16083 GbE Expansion Module – 4x Gigabit Ethernet
  • GW16084 Fiber SFP Expansion Module – 2x SFP Fiber cage

Ventana GW5400 and GW5410 boards and corresponding development kits are available now, GW5100/GW5200 will be available in Q3, and GW5300/5310 boards in Q4.  GW16081 mini-PCIe, and GW16082 Mini-PCI expansion boards appear to be available now, whereas Gb Ethernet and Fiber expansions modules will be available in Q4. Pricing can be provided upon request. You can checkout Gateworks Ventana products table for further details.
