How much power does your home lab take? (lemmy.world)

Mine runs at 30watts at idle.

That powers 4 switches, 1AP, and my proxmox system (framework laptop motherboard) which runs my router and my services.

What is everyone else's usage and what does it power?

My rack currently consumes about 300W. This includes the following hardware:

Dell PowerEdge R730 with 128GB RAM, 1x E5-2630 v3 (the second socket is unpopulated), 5x HDD and 4x SSD
MikroTik CRS309-1G-8S+ (8 port 10Gbit/s switch)
MikroTik CRS326-24G-2S+ (24 port 1Gbit/s switch)
MikroTik RB5009UPr (Router)
Whitebox NAS with Intel Pentium Gold G5400, 16GB RAM, Adaptec RAID controller in IT mode, 19x HDD and one SSD

That's a power efficient setup, nice!

I believe I could reduce the power consumption by ~50W-60W by replacing the R730 with a modern "consumer" mainboard + CPU. But I need two power supplies (I had some issues a few months ago with my UPS) and iDRAC/IPMI is so convenient that I don't want to miss it anymore.

I'm also currently searching for something power efficient to replace the Pentium in my NAS. Reason for that are some problems with bad RAM a year ago. ECC RAM would be nice to have, so that I can be notified when a RAM stick goes bad. I currently do not know for how long the old RAM stick was bad and which files may be corrupted because of that (I do not use a checksumming file system such as ZFS or BTRFS on my NAS).

I like your setup.

My stack is R730s with MD1200 DAS. Using about 380watts.

Is your nas on Ext4?

I like your setup.

Thanks :)

Is your nas on Ext4?

Yes, all HDDs in my NAS are formatted with EXT4. I don't use RAID because there are mostly static files stored there and the drives are configured to spin down after 30 minutes of inactivity.

MD1200 DAS

How loud are those? I've heard that the Dell PowerVault DAS arrays are quite loud.
