I have a test unit set up with 5 Antminer S5's , The Bladecenter appears to be handling it OK. but I think this has got to be close to the max for it. I am wondering if it would be safer to just run 4 per Bladecenter. Can't complain about how loud the S5's are since you can not hear them over the Bladecenter's fans.
