WTB [NY/NJ] Ucoustic Edge-3 12U

[mental0w]

Hi folks,

I just got some R740xd / R340 / Juniper EX3400 / Opengear IM-7200 from work.. and would like to actually run them..
I live in a modest 2b2b so the R740xd alone is absolutely insane - min fan speed is 50% (apparently due to the 10G interfaces?).

Soo.. I'd like to purchase a Ucoustic Edge-3 12U as it appears to be the best in its class!
Thanks~~

I dont have one, but fan speed at 50% seems way to much. Any 3rd party components in the server? My dell server is somewhat quiet. R7910 and r720s.

Thank you for sharing your thoughts..!

Some screenshots below.. this is completely idle - I've just installed the OS and never SSH'd in. This server is fresh out of the box, it barely ran at work, just enough to be initially configured, then it was left powered off and boxed for about a year.

I see your problem…. You have set your minimum fanspeed to 42%

You can also put on fanoffset, and ssh to the idrac and set the speed to low. I think this command should work: racadm set system.thermalsettings.FanSpeedOffset 0

Dell PowerEdge fan speed - change fanspeed offset | DELL Technologies

The BMC/iDRAC in is programmed to set fan speed min/max and adjust values based on factors like ambient temperature and system configuration. Depending on configuration the system may run the fans ...

> You have set your minimum fanspeed to 42%

I wish I could set it to 10%.. It actually have it set to "Default" usually, but clicked on "Custom" for showing you - it won't let me go below 42, so I'm guessing that's also what "Default" does..

> You can also put on fanoffset, and ssh to the idrac and set the speed to low. I think this command should work: racadm set system.thermalsettings.FanSpeedOffset 0

racadm>>racadm get system.thermalsettings.FanSpeedOffset
[Key=system.Embedded.1#ThermalSettings.1]
FanSpeedOffset=Off

racadm>>racadm set system.thermalsettings.FanSpeedOffset 0
[Key=system.Embedded.1#ThermalSettings.1]
Object value modified successfully

racadm>>racadm get system.thermalsettings.FanSpeedOffset
[Key=system.Embedded.1#ThermalSettings.1]
FanSpeedOffset=Low

It looks like Fan Offset takes the 42-43% default and adds 25% on top.. After setting the FanOffset back to 255 (None) -->

Hmm… we jumped off the Dell train a few generations ago, so i have not worked with these servers. But it the iDrac and nic firmware up to date? Could it be you are running IDRAC version 3.20.20.20 or 3.21.21.21?Also what is the server alarming for in the system and power tabs?

 

[mental0w]

Haha thanks tough Sogndal94 Running 5.10.30.00 after using the online update tool yesterday (pointed to downloads.dell.com). The power alarm is due to the fact that I have not plugged the 2nd PSU. Plugging it in, or clearing the alert logs does not change the min fan speed (which is down to 39% min now.. for some reason it fluctuates a bit)

One last attempt Have you tried to enabling Sound cap? https://dl.dell.com/manuals/all-pro...rs-solution-resources_white-papers3_en-us.pdf

 

[mental0w]

I did but it seems that it did not change anything at all I will try again.. I also might just start removing some devices like the BOSS S-1 raid card, the Intel network card or whatever else can be taken out.. and see if it makes any difference..

Otherwise it’s either uCoustic if the floor can withstand it (308lbs empty..! I’ve asked the building whether it’d be permissible on the hardwood floor..), either eBay for all the gear.. :’[

edit 9000: 40 dB on that document, oh I wish!

 

[Sogndal94]

Let me know if it helps with removing stuff. I have been thinks about this all evening

I would try putting that second power supply in and rebooting. I know an IBM DAS, a Dell DAS and a few other machines that I've heard of will go crazy with the fans with only a single power supply. I'd also check the Dell specs to see if the noise profile is correct. Otherwise, like you said, bare bone it down to cpu and ram and boot it into the bios and let it sit--that should be very, very quiet.

 

[mental0w]

The saga continues.. for your own entertainment.. =D

Both power supplies plugged in..

No SAS HBA Controller, no BOSS S1+2xM2 SSDs, no PCI Riser


No SAS HBA Controller, no BOSS S1+2xM2 SSDs, no PCI Riser, no rear SAS block+2x 2.5" SSDs
(warning is missing rear SAS cable)

No SAS HBA Controller, no BOSS S1+2xM2 SSDs, no PCI Riser, no rear SAS block+2x 2.5" SSDs, no Intel 10G network daughter card
(warning is missing rear SAS cable)


All the stuff removed... that's quite some gear removed and some space for the air to go in the back.

I had high hopes for the intel 10G card removed, but with everything removed we went from 42% to 34% minimum speed for those "high performance fan, even without a OS loaded (bootloader only - the OS drives were removed).

It’s an improvement but without a network a card and it’s probably going to go to 9000% as soon as the Linux ISOs start transcoding at that rate..

Quite an interesting journey - I’ve got a Threadripper 3990x loaded with 256GB of DDR4, 2x RTX 3090 + 5 SSDs in PCIe slots - all in a consumer tower, and it’s actually tolerable, even though it flirts with the 70 degrees under AI load, it doesn’t sweat too much! So pretty sad that the bootloader is enough to push the Dell controller that high.. without ways to configure that stuff.

Looks like I'm gonna need that uCoustic rack after all if I want to work in the same room as that cute guy.. I was actually thinking about the Sysracks earlier asthey are local to me (NY) and as it's wayyy cheaper but it seems that it will be much less effective than the uCoustic given it's only got a glass door as opposed to an insulated door.
