@nprofile1q... more like weyland-yutani

@nprofile1q... lol fun. This is a VM so the acpi tables should be fine. But something ain't right.

@nprofile1q... DM me an email address?

For background: it's a scientific computing / laboratory data analysis tool using a node graph editor and shader-based number crunching to analyze GB/s of data. Normal desktop application toolkits aren't really designed for this use case hence the game-esque tech stack.

See here for a short video of the tool in action. https://www.youtube.com/watch?v=Sx9cRnWOk2A

We've got a bunch of UI art to do but limited budget (it's an open source project funded by donations and my personal funds) so I'm moving slowly. The near term priority is a revamp of the toolbar to fix some confusing parts and add a bunch of new icons.

@nprofile1q... Are you interested in some toolbar icon work? The application isn't a game but it's a game-adjacent tech stack (dear imgui, vulkan, etc).

The VMs also have been having trouble *shutting down*, when I run "shutdown" from the VM they seem to hang in a not-fully-off state and I need to force-stop the instance.

This doesn't happen with any other Linux guest on the same hypervisor.

And, of course, to continue working toward some of my planned non-lab energy efficiency upgrades like a heat pump water heater.

And to be thankful for my rooftop solar. Month to date, 56% of my total energy demand was locally sourced and not imported from the grid. Obviously this won't be the case during the winter but it's sure welcome now!

As of my last power bill, my effective rate after taxes and fees was $0.217/kWh.

So ignoring contributions from solar as well as non-unity PUE, the annual power OPEX for the identified equipment is:

* Ceph cluster: $545
* Network: $315
* Backup server: $400
* Rest of the lab: $6343

The backup server seems like an easy target. I can't get rid of it, the deal I have with my friend is that I host her offsite backups and she hosts mine and no money changes hands. But it's full of old enterprise SAS drives that are totally not necessary for something whose performance is dominated by internet latency/bandwidth and I am more than willing to buy some hardware upgrades to make it more efficient over the long term.

The current network stuff I don't see changing much, I need high bandwidth and am willing to pay for it. The old Cisco switches are likely much more power hungry than the currently identified loads and I already have a migration plan to get off them (eventually).

The storage cluster is probably also not changing.

So I guess the next step is to buy another managed PDU and collect more data, plus work on making the backup box more efficient.

This rack also contains (not yet on managed PDUs):

* One more of the same model 40/100G switch (so likely another ~40W)

* 3x old Cisco 24-port switches that I expect are major power hogs and plan to replace with LATENTRED's whenever I have time to finish them. I suspect these are 100+ watts a pop.

* The VM server (probably in the 300-600W range)

* Label printer that probably doesn't draw much

* PoE injector feeding three 802.11 AC access points and six security cameras throughout the building

* Crash cart monitor that's normally turned off but plugged in

So far, I've accounted for about 670W of the ~4 kW base load power the lab draws at the UPS, or about 17%.

Here it is broken down by category:
* Storage - the three Ceph cluster nodes
* Networking - core router and one of the 40/100G switches
* Backup - my friend's offsite backup server I host

And the UPS power is only 63% of the building-wide power consumption (average 6.3 kW). I have no data so far into where that 2.3 kW is going - some is normal house stuff like cooking, lighting, HVAC, the living room TV, etc. But a nontrivial fraction is also going to lab overhead like lighting and cooling and unless I get a current transformer on the minisplit feed I won't have visibility into that.
