I've had a hell of a time trying to find out when and how a Dell PowerEdge server (in my case we have a bunch of R210IIs and R620s with iDRACs) deals with overheating. I don't want to wait for the CPU to self-preserve, and ideally the server itself should deal with high temps over a period of time by issuing a self IPMI command to the OS to power down before a critical threshold is reached. e.g. at 55C, issue the IPMI command to the OS, if the server reaches 80C, pull the plug, etc...
The problem is that all of Dell's documentation is unclear on when or how a server shutdown from overheating occurs.
My question is if Dell supports thermal management graceful shutdown like this, or it's some fine print or unclear documentation on the critical temperature where it'll simply pull it's own plug? Is Dell OpenManage necessary to support this?
I really would like to avoid having to run a dedicated management server plugged into the various networks (trying to avoid bridging between networks through a single management point) to remotely manage shutdown like this. It would be a single point of failure which is also subject to the same hardcoded or inflexible thermal conditions as my servers themselves.
My R620s have iDRACs in them. I included them for the iDRAC's remote management features, but at this point I'm disappointed the iDRAC is incapable of handling this. It's thermal settings are limited to controlling fan speeds and the horrible documentation and in system help doesn't actually say when shutdown could occur.
Any real world advice is greatly appreciated! Thank you.
