PLX, Kontron offer PCI Express over VPX

PLX Technology and Kontron have developed key technology to use PCI Express (PCIe) technology as a high performance backplane interconnect in VPX embedded systems.

Built around PLX ExpressLane PCIe 3.0 (Gen3) switches, Kontron's VX3042 and VX3044 Intel Core i7-based single-board computers (SBCs) routinely achieve 5.6GB/s in data throughput between any boards in a VPX rack.

The Kontron VX3042 and VX3044 Intel Core i7-based SBCs use PLX's PCIe Gen3 switching technology along with Kontron's own VXFabric software. In addition to having two 10Gb Ethernet channels already featured on the boards, VXFabric implements TCP/IP over PCI Express as a second data plane for higher-performance embedded computing. This combination of features enables efficient system convergence, as all devices and sub-systems offer native PCIe, which permits immediate use of an existing infrastructure, thereby lowering latency, cost and power. Kontron VXFabric provides the software between the PLX ExpressLane switch and the bottom of a standard TCP/IP stack, which allows the boards to use their existing TCP/IP-based application without having to be modified.

"Embedded computer systems rarely realise a tenfold increase in I/O performance and with absolutely no porting effort," said Vincent Chuffart, product marketing manager, Kontron. "However, the Kontron VX3042 and VX3044 SBCs put this powerful capability directly in the hands of users, allowing them to leverage PLX PCI Express switching and the ubiquitous TCP/IP socket interface. We feel this type of solution is bound to be well received in the market."

"PCI Express has emerged as the most sensible backplane interconnect solution available," said Gene Schaeffer, vice president worldwide sales, PLX. "This is demonstrated in how our switch features help achieve 5.6 gigabytes per second and efficient use of the TCP/IP stack implementation in the VPX ecosystem."

PLX switches offer the ability to combine different data types in a single converged pathway. Data (compute, communication or storage) are created and consumed as PCIe on each of the slots in the rack, delivering efficiency both in hardware architectural and software usage.

Kontron VXFabric software simplifies and accelerates application development and helps to extend application lifecycles as it enables migration to emerging hardware communication standards, such as 10G and 40G Ethernet. The software streamlines the task of inter-CPU communication in VPX system architectures.
