Embedded computing specialist Kontron Australia announces an industry breakthrough in the deployment of PCI Express (PCIe) technology as a backplane interconnect solution.
Built around PLX ExpressLane PCIe 3.0 (Gen3) switches, Kontron’s VX3042 and VX3044 Intel Core i7-based single board computers (SBCs) routinely achieve 5.6 GB/s in data throughput between any boards in a VPX rack.
PLX switches enable different data types to be combined in a single converged pathway. Data is created and consumed as PCIe on each of the slots in the rack, delivering efficiency 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.
The Kontron VX3042 and VX3044 Intel Core i7-based SBCs leverage PLX’s PCIe Gen3 switching technology along with Kontron’s exclusive VXFabric software. In addition to having two 10 Gigabit 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 subsystems 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.
The VX3042 and VX3044 represent Kontron’s third generation of 3U OpenVPX SBCs, both using Intel Core i7 processors and featuring native support for 10GB Ethernet and PCIe Gen3. The boards are specifically designed to provide the ideal combination of leading-edge performance in CPU computing power and I/O bandwidth.
Vincent Chuffart, product marketing manager, Kontron explains that embedded computer systems rarely realise a 10-fold increase in I/O performance and with absolutely no porting effort. 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.
According to Gene Schaeffer, vice president worldwide sales, PLX Technology, Inc., PCI Express has emerged as one of the most sensible backplane interconnect solutions available, which is demonstrated in how their switch features help achieve 5.6 GB/s and efficient use of the TCP/IP stack implementation in the VPX ecosystem.
