FUJITSU - Server fan control

I am using Proxmox on a Primergy RX2540 M2 with 2 CPUs and 128GB RAM. Also HW RAID for the storage.

The server was running ESXI before and I had constant fan speeds at constant temperatures. At temperatures below 20°C the server was very quiet and from 25°C it became increasingly very unpleasant. We don't have a server room at the site and it is located in an office where there is air conditioning that is switched on as needed.

Since the server is running under PROXMOX, the behavior of the fans is significantly different. In completely irregular intervals the speed of the fans increases or decreases, although the room has no other temperature. The load of the server also does not correlate with the speed.

I got used to a relatively constant fan speed, but this spontaneous, irregular up and down at unpredictable intervals is annoying.

Is there any way to control this? Can you see what the system thinks might be necessary?

hi,

what is your current workload like?

maybe checking htop, atop etc. similar tools for a while when the server is running is a good idea to pin the issue down.

The load-average is around 0.75 or 1.
But there is no apparent connection between the CPU load and the fan speed. It can be high at 5% CPU load and low at 50%. But other components are hardly load-dependent in terms of consumption and waste heat.

And while the speed used to increase in quite fine increments when the temperature increased (ESXI), it's now rather coarse increments.

I would like to know if there is a config file that can be adjusted. Or if I can see if the system gets meaningful values from the sensors at all.

you could install lm-sensors and run watch sensors

This is what it looks like all the time.

The CPU varies a bit and these "be2net" are fixed at exactly 59°C.

Did you run sensors-detect? I am missing the fan speeds in the output. Also you can check the data through IPMI, Fujitsu usually has a good load of sensor data there as well.

Yes, that's all he finds.

Code:
root@pve1:/# sensors-detect
# sensors-detect revision $Revision$
# System: FUJITSU PRIMERGY RX2540 M2 [GS01]
# Board: FUJITSU D3289-B1
# Kernel: 5.4.78-2-pve x86_64
# Processor: Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz (6/79/1)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
Found `IPMI BMC KCS' at 0xca2...                            Success!
    (confidence 8, driver `to-be-written')

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Wellsburg (PCH)

Next adapter: SMBus I801 adapter at 0580 (i2c-0)
Do you want to scan it? (YES/no/selectively):

Probing for `SMSC EMC1063'...                               No

Next adapter: mga i2c (i2c-1)
Do you want to scan it? (yes/NO/selectively): yes


Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Driver `to-be-written':
  * ISA bus, address 0xca2
    Chip `IPMI BMC KCS' (confidence: 8)

Note: there is no driver for IPMI BMC KCS yet.
Check https://hwmon.wiki.kernel.org/device_support_status for updates.

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

"Found `IPMI BMC KCS' at 0xca2... Success!
(confidence 8, driver `to-be-written')"

LOL?!

Yup, there seems to be no module for that one in the kernel. The ipmi interface (openipmi) should still provide some additional data. But Fujitsu also has its own software and plugins, maybe these may help.

Otherwise you can disable the C/P-states and run the server in full power, that provides no sound variation. ;)

Well, I was already there when the server tested its fans.
I prefer not to be around when the server gives the impression of launching straight from the rack into space.

I'll see what software they have and see if that helps me ;)

This sounds like an adventure, which is way out of my league.
Well, then you may look into the openipmi and query the values from there.
