Good thought, but unlikely here... whole machine room is on a UPS
(which seems happy and has no events).
While these machines are mostly in one rack, that rack has 8
PDUs on separate circuits. (All of the SC1435s are running on 120V,
single phase from a 208V/3 phase distribution system). Machines with
issues are spread out across the PDUs (and multiple phases).
I'm more concerned/thinking that with 70-71 degree F intake air,
the SC1435 can't deal with running "flat out" in an HPC environment.
