[edit] Automotive section

I removed the entire automotive section as it is basically a cut and paste copyvio from http://www.easis-online.org/wEnglish/links/index.shtml see the sparc section at the bottom. -- SusanLarson ^{(User Talk, New talk, Contribs)} 01:49, 12 January 2006 (UTC)

[edit] Error in description

This part of the write up "In a triply redundant system, the system has three sub components, all three of which must fail before the system fails." is massively wrong as a triple redundant system is a 2oo3 system meaning that it needs 2 working components to continue to work. Correct would thus be: "In a triply redundant system, the system has three sub components, two of which must fail before the system fails."

For the ability to sustain operation with only 1 correctly working component a 1oo3D system would be needed ('D' for diagnosed). Alas that typically means that internally each component is replicated once for diagnosis purposes. --Markus Baumeister, 18.7.06

I'm confused about this too; it would seem in such a system, if two failed and one remained operative, there would still be no consistent way for the properly functioning system to "out-vote" its peers. At best, it would be a three way tie. At worse, both malfunctioning systems might fail in same way and give the same consisntently wrong results, out-voting the functioning system 2 to 1.
