What is OpenVPX?

VME bus Variant: VPX
Compatible Architecture: VPX, VPX-REDI

OpenVPX has opened up new definitions for VPX backplanes and systems. This includes defined Module Profiles, Slot Profiles, backplane & chassis configurations, secondary expansion fabrics and control planes, and higher speed fabric options.

The VPX Modules and Slots across the backplanes have been given definitions so that similar Modules will work within certain Slot configurations. The backplane Configurations have been defined to show the collection of Slot profiles it entails, including information on the data rate, routing topology, and fabric used. Now, the integrator can determine that a daughter card Module from “X” company can be used in the same backplane slot as “Y” company’s, when both Module Profiles specify the same Slot Profile.


  • The backplane slot profile table describes the height, type of slot (centralized, distributed or hybrid), the pitch, RTM connector, the corresponding payload and switch cards that plug in, and the control and dataplane data rates.
