Cyclone Microsystems' PCIe2-2710 Eight Slot PCI Express Gen2 GPU Expansion System allows system developers to expand one host PCI Express Gen2 slot to eight additional PCI Express Gen2 Slots via a Gen2 x16 (80 Gb/s) PCI Express Expansion cable. With extensive processing power now available on board level GPUs, the PCIe2-2710 supports the integration of up to eight double-width PCIe Gen2 GPU boards like NVidia's Tesla C2050/C2070 GPU Computing Engine. In this manner, the host and expansion system based GPU boards are coupled at speeds of up to 80 Gb/s.

The PCIe2-2710 Eight Slot PCIe Gen2 GPU Express Expansion System is a turnkey system which includes a PCIe2-426 Host Bus to Expansion Cable Adapter, a x16 expansion cable and the PCIe2-429 eight slot expansion backplane mounted in an industrial 19-inch chassis. The system supports  expansion cable lengths of either one or three meters.

The eight x16 PCIe slots are double-width spacing, providing ample room for eight full length, double-wide PCIe cards such as the latest generation of GPUs. Ample power for multiple GPUs is provided by either 3240W or 2180W N+1 redundant supplies housed in a 5U chassis. For lower-power requirements, a standard 1200W power supply option is available in a 4U chassis. All power supply configurations provide eight 6+2 PCIe power connectors. The 5U chassis provides an additional eight 6-pin PCIe power connectors to meet the additional external power requirements of PCIe Gen2 GPUs and graphics cards.

All Cyclone Microsystems' expansion systems are host processor, host operating system, and computer manufacturer agnostic. The sole determination of compatibility is the availability of a x16 slot (either Gen1 or Gen 2) and host computer’s BIOS’s capability to enumerate a large quantity of bridged bus segments. Our Expansion  System's PCIeG2 switch appears as bridged bus segments to the host BIOS.

The Expansion system is optionally supported by an Intelligent Expansion Chassis Monitor to report temperature, fan speed and power supply parameters via HTTP or SNMP.
