In rugged embedded computing, it’s tempting to treat every new form factor as a replacement for the last one. VNX+ is often described that way, as “the next VPX” or “VPX, but smaller.” That framing misses the point. VPX (ANSI/VITA 46/48/65) and VNX+ (ANSI/VITA 90) were never meant to compete for the same slot in the same system. They were designed to solve two different halves of the same SWaP (Size, Weight, and Power) problem, and, critically, to interoperate. A system architect can put both standards in the same chassis, on the same backplane, in the same program, without redesigning either one around the other.

This article looks at why that’s true: the size and power envelopes that define each standard, the markets each one targets, and the mechanical reality that makes it possible to drop a VNX+ module directly into a VPX chassis using a passive adapter,  a product SundanceDSP offers today, the VNX+ to 3U VPX Adapter.
