VPX is a broadly defined technology utilizing the latest in a variety of switch fabric technologies in 3U and 6U format blades. OpenVPX is the architecture framework that defines system level VPX interoperability for multi-vendor, multi-module, integrated system environments.
The OpenVPX framework defines clear interoperability points necessary for integration between Module to Module, Module to Backplane and Chassis. OpenVPX recommends, but does not specify development systems to assist evaluation, prototype and development of VPX systems. OpenVPX will evolve and include new fabric, connector and system technology as newer standards are defined.
Currently there are 16 profiles for 3U and 19 profiles for 6U backplanes in the OpenVPX specification.
