Despite the fact that OpenVPX is an open standard architecture, there is a significant amount of variation of system platforms. The application needs for OpenVPX systems continue to evolve rapidly. New challenges brought by the SOSA [Sensor Open Systems Architecture] Consortium’s efforts; new complementary VITA [VMEbus International Trade Association] standards; size, weight, and power (SWaP) concerns; the expanding number of backplane profiles; and SpaceVPX implementations are requiring a versatile approach by the backplane/enclosure developers.
VPX and VXS mean higher power levels, but they also mean hotter enclosures. However, conduction and liquid cooling methods are helping designers face the challenge, but both methods have their trade-offs.
