LSI MegaRaid – get HDD temperature

Take a look a ITwatchdogs. Their weather goose line looks very nice. They monitor temp, light, sound, humidity, etc.

Here's a list of vendors (not APC) that have other products.

What I use in my data center appears to be a discontinued model. What ever you end up using, make sure that:

• They use SNMP, not some special protocol.
• Have remote temperature sensors. (I don't know if the netbotz do ...)

Currently the temperature monitors are hung from the middle of the drop ceiling.

Using a simple network monitoring application (zenoss, munin, nagios, etc) just monitor for threshold violations and create alerts for your pager/email.

You should also look into buying a handheld thermometer and walk around to every part of your datacenter/comm closet (including corners) to find any hotspots.

It's recommended that you keep an average temperature between 20 and 21 degrees, but you can vary between 10 and 27. Going below or above that is not advised, so yes, technically 33 is too high.

The real question is what is your inner case temperature on your servers. Usually server rooms have 1U/2U servers not regular tower servers and that's probably what those guidelines are based on because they are much closer together and share heat.

Purely from a "server room" perspective it's too hot; but for the towers check what the case temperature is (with a free app or something) and check the recommended values.
