[datacenter] Measuring temperature
Hello,
Simple question first: What is the typical temperature of the
motherboard in your 1U/2U Intel or Sun servers that are housed in a
well-run data center?
This leads to some more detailed questions: When people say the "ideal"
temperature for a data center environment is 74F (or something like
that), where is this temperature being measured? This is probably
easier for a non-raised floor facility. Saying the room temperature is
74F, does it imply that the air entering the chassis of the typical
Intel server from its front is 74F? And that the motherboard
temperature shouldn't be that much higher than 74F?
What about a raised floor facility where air is forced up into the
cabinet and the front cabinet door is solid? In theory, the cold air is
forced upward in the front of the cabinet, enters the front of chassis,
and then exit through the fans in the back, and rise up where it's
taken out of the cabinet by additional fans. Sounds good in theory.
Where should we measure the temperature here since room temperature
doesn't reflect the condition inside the cabinet.
Any insight would be appreciated.
Thanks,
Patrick Lee
