Big IP F5 2000 Operating temperature

Dear Iain , No actually the data center is cooled efficiently ( has a stable 23 degrees Celsius ) but the location where the specific rack with the LB is in the position where it doesn't get optimal cooling ( also that rack happens to be full). So i was wondering since it spikes for a short period of time to 41 ,42 or 47 the highest with the fans not even working full speed at 20k ( mostly around 16k rpm ) maybe to increase the Nagios threshold to avoid that. As no expert in F5 thought better to ask first.

Rack move time then. Get it optimal cooling.

Yes this is one of the solutions which will be implemented to solve this but i was wondering how the temperatures mentioned in the product info sheet are translated. Like 0- 40 Celsius is for the device internal temperature or for the ambient air temperature. And what are the warning temperatures for the device it self cause i need to set up my monitoring program not only to warn me about the temperature if exceeded more than 40 degrees but also to have a flag when it reaches "critical".

Apologies - Seems I have crossed my wires somewhere.

It would be worth raising a direct support case with F5.

Just for a reference , in our data centers we have 2000s and we are monitoring chassis and cpu temperatures. In both cases I havent seen them reaching over 30 degrees celsius for active unit. If you are seeing these temperatures constantly above 40 (getting closer to 50) I would definitely consider moving them to cooler rack.

Keep in mind direction of the airflow from devices in nearby racks. Maybe changing front with the back would be enough to cool it down.

Yes Actually i was informed that in the same rack where there are also some blade servers the were installed front to back so they are receiving warm air instead of cool but this was implemented like a few years ago and only recently started to appear as warning In Nagios.

They don't operate at those temperatures they only spike so yes ofc adjusting the cool air flow is a must but i am also waiting from F5 to know the warning temperatures or the operating internal temperatures as the 0 - 40 degrees is for the ambient air ( for sure the device itself can easily operate above 40 degrees internally).

Received an email from F5 " The threshold values are preset and defined by a BIGIP db variable. You can query these thresholds with the following CLI command:

: tmsh show running-config sys db platform.cpu.temperature.threshold .

Think the limit would be 75C on most platforms."

Posting this for future reference in case someone else is also interested in this.
