How Many Jigowatts Do You Use? (alien.top)

So ive never really paid attention to the power I consume running various servers over the years but now that ive cleaned up and consolidated im trying to gauge my power draw compared to others.

I run a Proxmox host with 13 HDDs, 6 NVMe drives and 2 U2 NVME drives, a Quattro P2200, RTX A2000, RTX 4070, Epyc CPU, HBA for HDDs, NVMe Card 4x4.

A Synology 2422 with 4SSD, 2 HDDs

A Synology expansion with 8 HDDs

I run about 500 watts off the wall for all this stuff and I think this is the lower end as I wasn't using the GPUs. That includes a couple switches as well. Very silent runs very cool.

What do other people consume?

4100 VA or about 2650 W...

Not including my office setup, that's just what's in the rack. MX7000 chassis with 7x MX740c blades, redundant 40G core switches, a fiber channel SAN, two 48-bay NAS with 10TB drives, and 240v power with a 5000W UPS.

Not including the AC for the garage that the rack is in.

And no, I am not a masochist.

2650 W

My whole flat uses less yearly

How on Zod’s green earth were you able to get your power factor to be that awful?!

[–] sshwifty@alien.top 1 points 11 months ago

Xeon processors in my case

Follow up question: how is your hearing? An actual blade setup would be loud as bombs inside a house.

[–] VaguelyInterdasting@alien.top 1 points 11 months ago (1 children)

Actually, the MX7000 is not terrible on noise comparatively. Not silent, obviously, but no worse than a typical 1U server.

Now, having that many compute modules may make that thing loud...

[–] audioeptesicus@alien.top 1 points 11 months ago

Yep. It's not so bad. I typically only have 4 or so blades powered on at a time, so it's not so bad. The MX9116N IOMs I have though require more cooling. Had I gone for the lesser ones, it'd probably be a little quieter.

I just calculated this would cost me £8272 p.a. ($10160) to run.

[–] audioeptesicus@alien.top 1 points 11 months ago

Ouchies.

Power costs me $0.09 kWh where I live, so it's far more affordable for me to run.

Or €15111 little tiny bitty coins in chocolate/beer country.

How did you got an mx7000?
