Hello John   That is the critical threshold for a long term safe operating temperature. The critical threshold that will force a shutdown is much higher. I don't know the exact temperatures, but they are usually based off of the critical threshold of the processor. The critical threshold of modern processors are in the area of 75-105 degrees celsius. Servers can get very hot before they shut down due to a thermal event. They should not operate for long periods of time above the listed thresholds, but they can operate at much higher temperatures than the listed thresholds.   By default we allow them to run until they hit the upper threshold that is usually based off of the maximum operating temperature of the CPU. If you do not actively monitor your servers then it would be advisable to use the BMC thermal management features to configure event shutdowns. By allowing the servers to go until they reach the upper threshold this will allow maximum uptime in the event of a CRAC unit failure or some other event that would affect server room temperature. This is typically the best option if your servers are monitored. This allows you to manage the shutdowns as necessary to best suit your needs during this type of event. Thanks
Hi, We recently had an air-con failure and had some very high temperatures recorded by serveral Chassis (>70deg C) Yet none of our blades turned off. I believe servers should shut down if a critical threshold is met (>47deg C) Is there a setting that needs to be enabled before servers will auto-shutdown over the critical temp or is this a factory default to do so? Thx, John Bradshaw
