OpenVPX Backplane Design: What is a Backplane Profile?
OpenVPX design can be tricky. At Pixus, we are happy to help walk you through the design questions and pitfalls. OpenVPX Backplane Profiles are routing configurations that match up with Slot Profiles & Module Profiles to ensure that each OpenVPX system is fully interoperable. Take the Profile in the image above: BKP3-DIS05-15.2.13-x.
BKP3 = 3U OpenVPX Backplane
DIS = Distributed architecture (vs Centralized or Hybrid)
05 = 5 slots
15.2.13 = The section of the VITA 65 specification where this Profile resides.
-1, -2, -3 = The backplane speed 3.125, 5, 6.25 Gbaud/s respectively
In this configuration, the distributed architecture has point-to-point routing to the slots versus via a centralized switch card. The 15.2.13 portion of the spec also details other elements of the backplane design, including which
"planes" are routed (control, data, expansion, management, and utility planes) which grouped different types of signals/functions, and more.
