Questions from my customer...
Hey guys,
My customer now has a bunch-o-blades deployed and has come up witht his question:
We just recently installed a new M1000e chassis which has the latest CMC firmware (1.10). We have noticed that fans 7,8, and 9 run at 12000RPM even when the other fans are only at 4000RPM. We see this even when the all the blades in the system have been powered down. The ambient temperature is read as 19 degrees C.
Our other M1000e chassis which is consuming more watts and has a previous version of the CMC firmware (1.01) does not exhibit this behavior.
Any ideas? Is this expected? Is this a firmware issue?

Are the iDRACs on all the servers up to date as well ?
Have you tried moving the fans around and see if this follows the fan or the slot the fan is in ?
I would say not expected, check the things above and lets see if we can nail it down.

I have moved the fans around, whichever fan is in slots 7-9 run at 12k RPM.
CMC: Hardware A01, Firmware 1.10
iDracs: Firmware 1.02 and 1.11
BIOS: 1.2.2 and 2.04
I will update the iDRACs and BIOS this weekend and see if that does anything.
We do not have redundant power supplies (so just 3), could this be a factor?
Also, I'm trying to monitor the fan speed via SNMP, however, I can not find in the MIB the fan speed, just whether the fan status is good or not.
Thanks!

I'm not sure if the power supplies change any of the fan algorithms with respect to the number. I'll have to test on our chassis on Monday. I can also point the thermal engineers at this thread (the one's that write the fan code) and see if they have input.

Example:
Fan-1 4923 RPM
Fan-2 4922 RPM
Fan-3 4883 RPM
Fan-4 4923 RPM
Fan-5 4775 RPM
Fan-6 4796 RPM
Fan-7 12581 RPM
Fan-8 12634 RPM
Fan-9 12509 RPM
Ambient_Temp 21C
CMC reports health as all good and I can personally verify the fans are running fast and loud ;)

Specifically there is a know issue with the PowerConnect 6220 modules that will be fixed in a firmware update for the switch, scheduled for Aug 26th release date.
So I'm guessing you have these switches ? Can you confirm ?

So we'll await the firmware update for these modules.
Thanks!

No idea how you use or compile them for your systems management package use. If you are able to use them, please let us know and maybe we can collaborate on a how-to to put up on the site.
