I have 10 C6100 chassis [40 nodes total] running a render farm. I ordered 8 spare boards, RAM and CPUs when I got the original order. This setup is obviously on a heavy load, maxing out the CPU for hours at a time. These are located in a server room with sufficient air-conditioning, with room temperature usually 70°, with directed venting pointed to the front panel of the rack which is consistently at 60°.
Boards are failing left and right. I'm down to 28 nodes online, and that's after I've used all of my spare boards. These systems will not POST, but when the board is inserted into the chassis the drive lights come on and the IPMI appears to be working. BIOS is set to defaults except for the virtualization options, so IMPI is sharing a NIC and not using the dedicated one. IPMI is not acquiring a DHCP address when connected to any port.
When connected to a switch both of the system NICs right-side LEDs light up as solid and don't flash. When the dedicated IPMI NIC is connected to a switch both LEDs light up and flash. Additionally a motherboard LED labeled CR24 flashes steadily [in a working powered-on board it is constantly lit]. See here for LED position — Motherboard
Any suggestions before I order replacement boards?
