This has been a very interesting thread. Google pointed me to this Dell document which specs some of their servers having an expanded operating temperature range *** based on the amount of time spent at the elevated temperature, as a percentage of annual operating hours. *** ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r710_User%27s%20Guide4_en-us.pdf I mention that because the "1% of annual operating hours" at 45 C would be two degrees higher than the 43 C stated as reached in the original email. It would seem that Dell recognizes that there might be situations, such as this, where the "continuous operation" range (35 C) is briefly exceeded. Tony Patti CIO S.

One of the suites that we're in recovered quickly but the other took much longer and some of our gear shutdown automatically due to overheating. We shut down remotely many redundant and non-essential systems in the hotter suite, and transferred remotely some others to the cooler suite, to ensure that we had a minimum of all core systems running in the hotter suite. We waited until the temperatures returned to normal, and brought everything back online. The entire event lasted from approx 18:45 until 01:15. Apparently ambient temperature was above 43 degrees Celcius at one point on the cool side of cabinets in the hotter suite. For those who have gone through such events in the past, what can one expect in terms of long-term impact...should we expect some premature component failures? Does anyone have any stats to share?
