VNX modules use the compact VITA 74 specification which defines an extremely small form factor. This form factor is roughly 50 percent of the weight and 30 percent of the volume compared to a typical 3U VPX.
The VNX specification defines the physical size of the two standard size modules, the module connectors, and the pin assignments of the signals on the module connector.
VNX signal mapping and bus structure was derived from VPX, specifically VITA 46, providing inter-module connectivity.
