Can you tell if the backplane supports SGPIO? If it and your RAID card do, and things are wired up correctly, you can tell your RAID card to Identify the drive and it’ll blink the LEDs. I just configured a Supermicro chassis to do this with an Adaptec controller.

Several locations.

• bunch of metering smart plugs flashed with Tasmota, feeding into Home Assistant (power at the wall)
• UPS being polled by LibreNMS (difference in load Vs wall shows the UPS consumption)
• metering PDU polled by LibreNMS shows the server load
• PMBus PSUs in the servers report their own power consumption to the BMC

And after all this, I do… Nothing with this data.

My homelab got me my last 2 jobs and the one I’m switching to for significantly more money.

I gave it a passing mention in my resume and a couple of sentences in a cover letter. It got brought up in interview and I was able to talk through all the tech I had experience with, which sold them on me and got me an offer. Job I’m moving to, we only had a casual interview where I discussed my lab, and it turned out 90% of what they use, I’ve played with at home. Got an offer the same week.
