Portwell: COM Express 3.0 module optimized for network appliances

Portwell released the PCOM-B700G, a COM Express 3.0 Type 7 Basic Module based on the Intel Xeon processor D-1500 product family. PCOM-B700G is designed according to the new COM Express Type 7 standard. The module optimizes value models and service levels by running network applications securely and reliably on virtualization-optimized platforms. In addition to the PCOM-B700G, Portwell also introduces a Type 7 evaluation carrier board, PCOM-C700.

The new COM Express Type 7 standard is a new specification with backward compatibility to the existing Type 6 pinout. While the focus of Type 6 is on display-oriented applications with support for audio and video interfaces, the Type 7 pinout definition is designed for applications that do not require graphics support. Specifically, the COM Express 3.0 specification's Type 7 pinout, when compared to the Type 6 pinout, trades all the graphics interfaces for up to four 10GbE ports, and a total of 32 PCIe lanes. This makes it ideal for applications in micro server and the like that require low power consumption while supporting high computing performance and communication throughput.

This latest PCOM-B700G COM Express module extends Portwell’s product family of server-grade COM Express based platforms. Back in 2015, Portwell launched PCOM-B634VG, a Type 6 COM Express module, which was the first COM Express module featuring Intel Xeon® processor D-1500 series, 10GbE support, and integrated VGA. Based on PCOM-B634VG’s success, Portwell’s new PCOM-B700G Type 7 COM Express module extends the design from PCOM-B634VG, removes the VGA interface and adds NC-SI (Network Controller Sideband Interface) as well as more PCIe lanes to meet the COM Express Type 7 standard. The two 10GbE-KR ports on PCOM-B700G allow customers to flexibly design their physical interface on a carrier board in several modes, KR for backplane connectivity, copper (RJ45), or fiber (SFP+). And the NC-SI signals provide a way of connecting BMC (baseboard management controller) on the carrier board to achieve remote control and management.

Designed with flexibility, the PCOM-B700G is developed on a basic 125 x 95mm size with three DDR4 SO-DIMM slots, up to 48GB dual-channel DDR4 at 1867/2133/2400MHz ECC (depending on the SoC SKU), up to 8x PCIe 2.0 x1, 1x PCIe 3.0 x4, 1x PCIe 3.0 x16, 2x SATA 6Gb/s and 4x USB 3.0/2.0. Moreover, the PCOM-B700G module also comes with an option for wide operating temperature support with the range of -40 to +85°C (depending on the SoC SKU).
