HPE DL380 Gen10 w/ 6132 Gold idle power consumption too high!? (alien.top)

Hi there,

I am just surprised this machine I got from a refurbished sale has quite high power draw. Even when I remove all of the peripheral parts and just leave one CPU in the chassis, so remaining just:

- 1x Xeon Gold 6132 (14c/2.6 GHz, 140W TDP), 2x 32 GB RAM 2400 MHz

Even then, idling (no OS, just in UEFI mgmt.), the machine draws at least 112 Watts from the socket from which 64W go to the processor and 6 to the RAM (says iLo). The remaining 40 or so Watts are lost in the system.

When I install the 2nd CPU the CPU draw rises to ca. 120W, so I already got a good saving here.

Nevertheless I find this a bit too much, also considering some other testing labs results which seem to be significantly lower. For ex. see here, which supposedly not only shows CPU but the whole system consumption.

Do you have any explanation for this?

Thanks and cheers

hmmm, was thinking about this, too. Let me check!

Apart from that - I need this thing kinda job-wise and it has been purchased with several future tasks in mind. Will be a Proxmox server for Windows/Linux on ZFS. So the choice of hardware type is no accident.

But it was indeed difficult to find out about power draw in advance. I researched it but did not get any great results. Servethehome was a source but for ex. it was even impossible to find out what happens if you pull out one CPU. The opinions about savings went from 0% to 50%. The board servethehome uses is this one

Thanks anyway for the (unforgiving) comments ;) At least good to know it is not that much for a server of this type. I'll get back to this post after installing Proxmox and updated power draws.

It's a 14nm tech that Intel polished and polished, but remained 14nm tech. If power is a concern, look into Optiplexes , Ryzens, the new Intel CPUs, etc.
