A new 3U OpenVPX PCI Express and Ethernet hybrid switch delivers extremely high transfer rates in centralized VPX and OpenVPX platforms. With up to 4 x 6 Gen1/Gen2 PCIe backplane ports for the data plane, the VX3905 from Kontron provides ten times the I/O bandwidth found in systems deploying today and paves the way for a new generation of high-performance embedded computing (HPEC) applications. OEMs will benefit from flexible OpenVPX system designs, which enable application-specific configurations through centralized COTS backplanes. Owing to the open configurability of the Kontron VX3905, system developers can minimize development time and cost for specific system designs while enabling the reuse of these designs for other applications. 

The hybrid switch VX3905 is compliant with the OpenVPX VITA65 switch slot profile SLT3-SWH-6F6U-14.4 for highest compatibility in multi-board designs. It provides up to 24 PCI Express Gen 1/Gen 2 ports for up to 32 lanes, which can be configured ( x8, x4, x2 and x1) depending on the required bandwidth. This offers OEMs a maximum data transfer rate of up to four gigabyte/s per port for serial interboard communication, an extended lifecycle of OpenVPX applications as well as enough headroom for future high-bandwidth designs. The switch can also be partitioned into multiple PCIe subsystems in order for the centralized backplane to host multiple root complexes each being able to control their own peripherals. 

Up to nine Gigabit Ethernet ports are available on the VX3905 for the control plane, enabling dedicated system management for high availability. An optional SATA disk carrier in accordance with the OpenVPX VITA65 SLT3-STO-2U-14.5.1 profile facilitates central data storage for OpenVPX systems without the need to use valuable payload slots, further simplifying the system design. 

For customers to capitalize on the Kontron VX3905’s high bandwidth, Kontron offers the VXFabric software solution for interboard communication. With VXFabric on K 3U and 6U VPX processor boards, OEMs can use common Linux and TCP or UDP sockets. It decouples the application software from the low-level hardware management to simplify and accelerate application development. An additional benefit includes longer application life cycles as the software ensures migration to future standards such as 10G and 40G Ethernet on the backplane.
