After some soul searching for specific MTBF numbers I have come up with the below.
Supermicro use Telcordia SR-332 update with ARPP as our MTBF calculation standard to establish the foundation for MTBF/MTTF numbers. MTBF/MTTF numbers per server do not feature.
Operating Temperature 55 degree C
Electrical stress 50%, ðS = 1.0
Temperature stress curve ðT, from Curve 5
Quality Level Level II, ðQ = 1.0
Confidence Level 90%I have further MTBF numbers on individual supermicro components below
