Re: What to expect after a cooling failure

Hello,

In my experience with heating issues the only thing that really degrades
quickly in event of overheating are hard drives. If you had them spun down
it should be fine.

CPU / Memory / Motherboards will be fine.

The only other thing I can think of having possible issues are PSU's but if
they were powered off should be fine as well. Maybe melted wires but I dont
think it was hot enough for that.

Thanks

As some may know, yesterday 151 Front St suffered a cooling failure after
Enwave's facilities were flooded.

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?

Thanks
