Dell PowerEdge R730xd Fan Control: Difference between revisions

Line 1:

Dell provides an OpenManage BMC (Baseboard Management Controller) / IPMI (Intelligent Platform Management Interface) Program for changing some settings. This also applies to other models like the R730, etc., but watch out for naming conventions like "FAN1 RPM" VS "Fan1 RPM" (notice the CAPs).

=== The Problem ===

===The Problem===

Why control the fan speed instead of leaving it up to the server? Well, scattered information seems to indicate that if a "non-certified" PCIe card or perhaps disk drive is installed, the punishment, err, standard functionality of the Dell Controller is to ramp the fan speeds up to maximum. (Hint from here: https://www.dell.com/community/PowerEdge-Hardware-General/How-to-quiet-r730XD-fans-lower-idle-fan-speed/td-p/8349052)

===The Solution===

*Show all the available IPMI Settings: ipmitool -I lanplus -H WhatEverUserName -P WhatEverPassword sdr list full

Line 16:

*...and finally, if the power / mains are pulled then everything reverts to defaults and the above settings have to be input again.

*0x30 seems to indicate OEM specific "Extended" Settings, but why 0x30 0x30? Is that Extended, Extended Settings? Or is the second 0x30 Fan control?

*Is the 0x01 the command for Set?

SuperMicros IPMIView works (mostly)

Power Cap Policy / Policies are an interesting subject (for later), that can curb a power hungry system (thus cutting down fan speeds), but at a cost of performance: https://www.dell.com/support/manuals/en-us/idrac9-lifecycle-controller-v3.0-series/idrac_3.00.00.00_ug/viewing-and-configuring-power-cap-policy?guid=guid-8b420aae-ecdb-4d50-9cc9-13ac6669afd5&lang=en-us (yes, it says iDRAC9, but applies to 8 too)
