The SPARC T4-series CPUs are the first SPARC CPUs to ship with an automatic CPU throttling feature. If an Oracle ILOM alert shows that temperature is too high, a T4 CPU will reduce speed until the system cools.
Netra systems use a different thermal control mechanism than the non-Netra products. The NEBS system maintains temperatures at 27ºC to keep acoustic levels within NEBS guidelines.If you want to maintain optimal CPU performance and increase fan speed to cool the Netra system you must use the high-altitude settings in CMM Oracle ILOM firmware 4.1.1 (or newer).
If your server modules operate with sustained high CPU work loads at altitudes above 900m elevation, the system might “throttle” or slow down the server module CPUs to continue to meet the 27ºC threshold and the acoustic limits. The High-Altitude mode allows you to override the CPU throttling feature. However, if you use the High-Altitude mode, the CPUs will run hotter, and the fans will automatically speed up to reduce heat. The fan noise will exceed NEBS specifications.
See the Sun Netra 6000 Modular System Product Notes for information about using the High-Altitude Mode.
