SAN JOSE, Calif. – Chip designer PLX Technology, Inc. and board maker Kontron announced a design using PCI Express 3.0 to “routinely achieve” 5.6 GBytes/second in throughput between boards in a rack system.
The design uses PLX’s ExpressLane switch chips and Kontron’s VX3042 and VX3044 single-board computers based on the Intel Core i7 processor running in a VPX rack. The boards also use Kontron’s proprietary VXFabric software, geared for inter-processor communications in a VPX system.
VXFabric implements TCP/IP over PCIe as a second data plane in addition to two 10 Gbit Ethernet channels on the boards. The software supports links to the PLX switches allowing the boards to use existing TCP/IP application without modifications.
"Embedded-computer systems rarely realize a tenfold increase in I/O performance and with absolutely no porting effort,” said Vincent Chuffart, product marketing manager, Kontron in a press statement.
