GPU-XpanderOverview
Need to add killer 3D graphics or computing cores for high-performance computing (HPC) projects to your operators' desktop computers? Don't have enough expansion slots in your current desktop computers to add fast, 3D graphics or NVIDIA's Compute Unified Device Architecture- (CUDA) capable, number-crunching GPUs? Don't have sufficient cooling capacity or a hefty enough power supply to add high-end graphics or HPC capability to your organization's computers? Many host computers lack the 'watts and slots' to allow expansion. Cubix GPU-Xpander Pro 2 is just the ticket.

Add two NVIDIA® Quadro® FX 1800 / 3800 / 4800 / 5800, Quadro 4000 / 5000 / 6000 graphics controllers, two NVIDIA Tesla® C1060 / C2050 / C2070 computing processors or two NVIDIA® GeForce® GTX 465 / 470 / 480 Fermi™ controllers to any computer that has an available PCI Express (PCIe) x8 or x16 expansion slot by installing the host adapter in the computer's x8 or x16 slot, connecting it to the GPU-Xpander Pro 2, installing graphics drivers and voila! You have just added two powerful graphics controllers or CUDA-capable HPC controllers without buying a new computer.

Save Time and Money
Just because you need to add or upgrade to high-end, 3D graphics or math-intensive, HPC processors in operators' desktop computers doesn't mean you have to go to all the weeks of effort and meetings to obtain approval and all the considerable expense, not to mention all the work of installing and configuring new computers. Rather than starting from scratch, keep your substantial investment in your current computer hardware and simply add or upgrade to the most powerful graphics controllers or HPC processor cards on the GPU-Xpander Statementmarket -- at considerably less than the cost of replacing computer hardware.

Install the host adapter in each computer, connect it to Cubix GPU-Xpander Pro, install graphics drivers and within minutes, your operators are back to work. The operators have the same operating system configuration, the same desktop, the familiar applications and multi-monitor screens but now they also have the fastest graphics controllers or HPC- and CUDA-capable cores available. Screaming-fast, 3D graphics or HPC capability at a reasonable price and with only minutes of effort per operator desktop -- what an investment!

Minimal Impact on Operators' Desktop Space and Configuration
Your operators are busy, and they have neither the time nor the inclination to learn how to use efficiently a new computer, a new operating system, a new desktop screen configuration, or for that matter, a new use of desktop space. They want to keep working -- without interruption or changes to their routines. 

You need GPU-Xpander Pro 2 if the hardware and software combination you intend to use runs in your computer but causes over-current or overheating problems. GPU-Xpander Pro 2 is a hardware-only solution: no software required. GPU-Xpander Pro 2 provides its own power supply and cooling; it requires no power from the host computer. Simply plug the host adapter in your computer's PCIe slot, connect GPU-Xpander Pro 2, power up and install device drivers.

Boost Graphics or HPC Performance
Give your operators the graphical or HPC power they demand with Cubix GPU-Xpander Pro 2. When your operators return for their next shift, they'll find their desktop space unchanged, their desktop screen configuration the same as usual, but what a difference in performance! With two powerful, state-of-the-art 3D graphics or HPC controllers in their system, their applications and renderings will leave their expectations in the dust with fast, eye-popping performance. For example, you can upgrade to or add two NVIDIA® Quadro® FX 4800 / 5800 graphics controllers or two NVIDIA® Tesla® C1060 / C2050 / C2070 computing processors for each operator, giving them the performance they demand without the usual interruption that a new system causes.

Remember the importance of the CUDA-enabled GPU and its memory in 3D rendering and HPC performance. For 3D rendering, Cubix recommends at least 1GBye of GPU memory and preferrably 2GBytes to 4GBytes, depending upon the size and complexity of the scene to be rendered interactively or of the calculations required. Cubix GPU-Xpander Pro 2 offers a quick, simple and cost-competitive method for adding GPU power and memory to your computer.

Support and Troubleshooting

Quick Start

  • Install a GPU in the host computer and install device drivers.
  • Once drivers are working, move the GPU to GPU-Xpander, install the adapter in the host computer and connect GPU-Xpander to the adapter using the cable provided.
  • The host computer, if it is plug-n-play, will detect the new hardware configuration and install drivers.

Power on/off GPU-Xpander normally.

  • With GPU-Xpander Pro 2 connected to the host computer and running, shut down the host normally.
  • With GPU-Xpander Pro 2 connected to the host computer and powered down, switch on GPU-Xpander Pro 2 first and the connected host next; both will boot up.

Power off GPU-Xpander while running a PC or Mac Pro.

  • To run the host PC or Mac Pro without GPU-Xpander connected, power down the host, remove power from GPU-Xpander and boot the host.
  • When you are ready to run GPU-Xpander again, power down the host, connect power to GPU-Xpander and boot the host.

Quickly test that GPU-Xpander works with your computer motherboard as follows:

  1. Do not install graphics or other controllers until instructed to do so within this procedure.
  2. Switch off AC power to the host computer but leave the power cord connected.
  3. Install the Cubix host adapter in a PCIe x8 or x16 slot within the host computer. In an Apple® Mac Pro, install the host adapter in a PCIe x8 or x16 slot.
  4. Using a Philips #2 screwdriver, remove the 4 screws holding the GPU-Xpander top cover in place.
  5. Connect the external PCIe cable to the host computer port. Warning: Switch off GPU-Xpander power before connecting to or disconnecting from the adapter in the host computer.
  6. Plug AC power into the host computer and the GPU-Xpander.
  7. On GPU-Xpander, switch on the AC power switch next to the AC receptacle.
  8. Power up the host computer. The GPU-Xpander also powers on.
  9. Check BIOS configuration for spread spectrum settings for CPU and PCIe. Most vendors set spread spectrum to [Auto]. Change the CPU and PCIe spread spectrum settings to [Disable], save the settings and exit BIOS configuration, which restarts the computer.
  10. When the host computer starts up again, compare your LEDs to the illustration below.

    GPU-Xpander Pro 2 Interior
  11. Confirm that exterior Link LED and the interior Cable LED (D4) are lit green. The enclosure fan should also be spinning. If not, check the following:
    • Host computer BIOS settings for CPU and PCIe spread spectrum are set to [Disable]. If not, disable, save settings and exit BIOS, which restarts the computer.
    • Confirm that the Cubix adapter is firmly seated in a PCIe x8 or x16 slot within the host computer.
    • Confirm that the cable connector is firmly seated to the host adapter connector.
  12. GPU-Xpander is functioning properly once the Cable Link LED (D4) is either flashing or steady green. Proceed to the next step to install adapters.PCI Express Auxiliary Power Cables
  13. Switch off AC power to the host computer and the GPU-Xpander. Leave the power cords and the external PCIe cable to the host computer port connected. Warning: Before installing or removing cards from the GPU-Xpander, switch off AC power, leave the power cord connected and wait about a minute until the 5V Standby Power LED shuts off.
  14. Remove the appropriate end bracket retaining screws.
  15. Install the graphics or other controller(s) in the GPU-Xpander PCIe slot(s) connect PCIe auxiliary (aux) power cables (see the image at the right). Each GPU-Xpander provides two sets of aux power connectors, including two 6-pin connectors and one 2-pin connector. Your GPU may require a combination, such as two 6-pin receptacles, one 6-pin and one 2-pin or all connectors.
  16. Replace the end bracket retaining screws.
  17. Connect GPU video port(s), if present, to monitors. This step is especially important for Linux, because X Windows (X) will crash if you have not connected video ports to monitors. If you cannot connect monitors to installed GPU video ports, you can edit the Device section of /etc/X11/xorg.conf to define which GPU X should use as the primary display device.  For example:

    Section "Device"
        Identifier     "Device0"
        Driver         "nvidia"
        VendorName     "NVIDIA Corporation"
        BoardName      "GeForce GTX 480"
        BusID          "PCI:8:0:0"
    EndSection


    To determine the BusID for the GPU you wish to use as the primary display, run the scanpci tool discussed in Step 17.
  18. Power up the computer and the GPU-Xpander to confirm that the appropriate slot link LEDs (D2 and/or D3 in the image above) are lit green, which confirms that you have installed the controller(s) correctly in each slot.
  19. Confirm that your operating system (OS) has detected the new controller(s). For instance, in a PC running Microsoft® Windows®, check Windows Device Manager. Within Windows, you can also run GPU-Z, a utility available for free download here. In a Mac Pro, check /System/Library/Core Services/Expansion Slot Utility (read more here). In a PC running Linux, run the following:

    root# > XFree86 –scanpci

    Read more about scanpci here.
  20. If all the Cable Link and slot LEDs are lit green but your OS does not detect the GPUs, shut down the OS gracefully, power down GPU-Xpander and remove / replace the GPUs. Make sure that you seat each GPU firmly in its slot and that you connect all auxiliary power connectors properly. Switch on GPU-Xpander and boot up the host computer.
  21. GPU-Xpander Pro 2Install the appropriate graphics or other controller driver(s) using the vendor’s procedure. Apple Mac OS X 10.5.x (Leopard) and 10.6.x (Snow Leopard) do not support natively all NVIDIA® GPU products (e.g., GeForce® GTX 465 / 470 / 480 Fermi). If you want to use such GPUs with a Mac Pro, download, install and run a supported Linux derivative or Boot Camp 3.x, which is free for download (here). With Boot Camp installed, you can install and run Windows 7 on your Mac Pro and use NVIDIA Windows drivers.
  22. Confirm that the GPU-Xpander Desktop Pro 2 Fault LED (D1) is not lit amber. 
  23. Switch off AC power to the host computer and the GPU-Xpander. Leave the power cords and the external PCIe cable to the host computer port connected.
  24. Replace the GPU-Xpander top cover as shown in the image at the right and replace the screws holding it in place. Use all of the screws in the bag packed with the GPU-Xpander. Warning: Replace the cover as soon as possible to allow for proper cooling of controllers installed in the unit. Do not run GPU-Xpander without the cover for more than a few minutes.
  25. Power up the computer and the GPU-Xpander.

The Cable Link LED (D4) inside GPU-Xpander flashes green connected to some computers and shines steady green connected to others.

  • The Cable Link LED (D4) inside GPU-Xpander shines green, which indicates the link is 5.0Gbps. The host adapter is in a PCI Express 2.0 slot.
  • The Cable Link LED (D4) inside GPU-Xpander blinks green, which indicates the link is 2.5Gbps. The host adapter is in a PCI Express 1.0 slot.
    • LED blinking 0.5 seconds on, 0.5 seconds off indicates the link is 5.0Gbps with reduced lanes up
    • LED blinking 1.5 seconds on, 0.5 seconds off indicates the link is 2.5Gbps with all lanes up
    • LED blinking 0.5 seconds on, 1.5 seconds off indicates the link is 2.5Gbps with reduced lanes up
