Cubix GPU-Xpander 2U Rack Mount 2 Gen3 PCI Express (PCIe) Expansion Enclosure, x16 2 Dual-Slots

The Cubix xpander Rack Mount 2 is a 2U rack mount PCI Express (PCIe) expansion enclosure that enables connection of graphics or other controllers to a host computer. The host must have a PCIe x16 expansion slot available for the host interface controller.

With a HIC installed, a single host computer can support two double-wide graphical processing units (GPUs) inside xpander. It connects to one HIC. Rack Mount 2 provides two PCIe Generation 3 (Gen 3) x16 slots for GPUs or other PCIe adapters with multiple Input / Output (I/O) ports such as FireWire, USB 2.0 or high-definition (HD) audio. For example, use NVIDIA Compute Unified Device Architecture (CUDA) -enabled GPUs for rendering, high-performance computing (HPC) or HPC visualization. A HIC in a host computers PCIe Gen 3 x16 slot provides the full connection transfer rate with Xpander. For example, the HIC in a PCIe Gen 3 x16 slot provides a theoretical maximum transfer rate of 8Gbs x16 = 128Gbps.

Rack Mount 2 includes two cooling fans, a 700W power supply and a power cord as well as one 2-slot mainboard with risers, one PCIe x16 HIC and one external PCIe x16 cable. It does not include installation media because installation requires no driver or other software. The only drivers you install are those for the devices you install.

Quick Start Without Detail
Install a GPU in the host system and install device drivers. Once you have verified operation, shut down, move the GPU to Xpander, install the HIC in the same slot within the host computer, connect xpander to the HIC using the cable provided, connect power to Xpander Rack Mount 2. Boot the host computer. If the host operating system (OS) is plug-n-play, the OS detects the hardware devices and loads device drivers.
