When the raid controller is installed the system fans produce unbearable noise. When controller is removed the noise level drops and you can barely notice the machine is on. As per Online Chat Support's instructions the Bios was upgraded to version 020 (2010.02.04), the iLO firmware upgraded to 4.06 and the controller's firmware upgraded to version 3.00. Issue still exists. If the controller is removed upon boot the server upgrades BMC SDRR/CFG to 2.17.1.42 which kills the noise. If the controller is plugged back in the server upon boot downgrades the BMC SDRR/CFG to 2.17.1.41 which reintroduces the noise. Also tried replacing the raid controller with a plain P212 running firmware version 3.00 which causes the same behaviour.<BR /><BR />Please, anyone has an idea about this?
