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

Components Q'ty MTBF (Hours) Environmental Temp Motherboard 4 137,542 40°C Power Supply 2 242,944 25°C Backplane 1 1,653,441 30°C Fan 4 215,306 40°C Backplane 4 1,001,001 55°C Riser 4 9,359,790 55°C​

These figures are based over Twin 2 products in general

Let me know if you need further info
