One Stop Systems will be unveiling new PCI Express Gen 3 products at Embedded World 2012. Co-located in a booth with Bressner Technologies, OSS will demonstrate the latest in GPU expansion systems operating at the never-before speed of 128Gb/s per slot. In addition, OSS will show two new PCIe Gen 3 cable adapters, the PCIe x8 dual/quad board and the PCIe x16 switch-based cable adapter. These flexible adapters can be used in both expansion and networking applications.
GPU expansion enclosures are specifically designed to support high power-consuming Gen 3 GPUs with each slot operating at 128Gb/s. The 1U enclosure supports either two double-wide or four single-wide cards and the 2U supports either four double-wide or eight single-wide cards. The expansion enclosures cable to a host server through the PCIe x16 Gen 3 cable adapter which installs in the host server’s x16 slot.
The PCIe x8 Gen 3 dual and quad-port cable adapters are full-height, half length PCIe cards that can be used in I/O expansion and networking applications. The two-port board has one PCIe x16 edge connector and two PCIe x8 cable connectors on the slot cover. The switch is field-programmable to allow the different ports to receive or transmit data. Therefore, in an I/O expansion application, the two-port card can receive data from one server and transmit it to two I/O points. In the networking application, the ports can be set to non-transparent (NT) allowing server-to-server communication. The four-port card consists of the two-port card with two cable connectors and a mezzanine card with two additional cable connectors. This card supports communication between five servers with the addition of the OSS ExpressNet 2.0 driver installed on each server. It can also be used in I/O expansion applications installed in a host server and cabled to four downstream end points.
The PCIe x16 Gen 3 cable adapter is a half-height, half-length PCIe card with a x16 edge connector and a x16 cable connector. The PLX 8733 Gen 3 switch has an NT port, allowing it to be used in networking applications between two PC’s as well as in I/O applications from a host server cabled to a downstream end point. It’s also equipped with an internal DMA controller and spread spectrum clocking isolation. This cable adapter has the added benefit of operating in both the host and target modes with a field-programmable switch setting.
