So, I picked up a EMC-branded 1.92TB PM1633 SAS drive off of ebay, to toss into my ceph cluster.
After acquiring it, I slapped it into my Dell MD1220, and was surprised that it was not appearing in proxmox.
This is a short post to help correct this issue.
This is a very short guide, on passing a USB Coral TPU through to a Proxmox VM.

Interested in home automation? Here are a few of the prime day deals I would personally recommend.
Note, this is not a kitchen-sink post full of non-relaxant links, but, rather, a list of things I have hands on experience with.
Every single product linked below, will work with Home Assistant, 100% LOCALLY, without any required cloud services or subscriptions.
If, you need reasons as to why required cloud services are bad, see Reasons to avoid cloud products
Continuation of the home solar project.
Around Midnight, Saturday June 17th, a very strong storm passed over my house, and hit my town and surrounding areas with a 115mph wind gust.
Power was out for around two and a half days, in which case, I powered my house fully off-grid.
While- this doesn't sound like a huge deal- do note, I was able to maintain climate control in my home, along with my ENTIRE rack of servers.
Why is everyone angry at reddit??
What went wrong?
A very short post, with a few links.
Want to learn more about how to use the fediverse?
Here are a few short tips to get started.
My wife presented me with a unique challenge recently.
"The cats keep getting on top of the kitchen table, and getting hair everywhere!"
So- the logically minded person I am- I decided to build a home-assistant integrated device for keeping cats off of the table!
I present to you, the FADD. Feline Area Denial Device!
Around a year and a half ago, I installed a Pioneer Mini-split and integrated it with Home Assistant
I used a local integration, which had a cloud dependency for the initial setup. And, since installation, it has been working flawlessly.
However, last week, it completely stopped working and I was unable to reinitialize it.
So- Today- I will be replacing the midea dongle, with a device running esphome.
Going over the history of my home network from the previous three years... and...
Deploying a Brocade ICX-6450 and Dell R730XD, without increasing power consumption.
In an effort to monitor the consumption of everything- I ran across an unusual problem.
When connecting my core switch to a ESPHome flashed smart switch, I noticed two things-
So, I set out to see how I could customize my configuration to be suitable for managing my core switch.
I will be implementing:
Everyone wants to monitor energy consumption. Everyone wants to automate their home.
The Sonoff S31, is a pretty low-cost way of doing this.
This is a very quick post on how to take a sensor- such as sensor.grid_power and split it into sensor.grid_power_in and sensor.grid_power_out.
This can be handy if you need a separate sensor for energy/power in, and energy/power out.
For this short post, I will be splitting sensor.battery_power into sensor.battery_power_in and sensor.battery_power_out
This is a quite guide on creating a real-time sankey diagram to show your current energy usage.
Starting your A/C compressor generates a massive inrush current. Many inverters will have issues getting the motor spinning.
In the case of my 3.5 Ton unit, the L.R.A. (Locked rotor amps) is 112.0 amps @ 220v (24,640 watts). This is far more current then my inverter can provide. This is the amount of amperage which it can potentially take to start the compressor motor.
This post, describes how to install a soft start, which will allow your compressor to easily start off-grid using your solar array with inverter and batteries, or via a smaller generator.
Continuation of the home solar project.
Part 4 of the home solar project. Adding monitoring tools and hardware.
Will be adding Iotawatt for per-circuit energy monitoring, and solar-assistant for monitoring the performance of my inverter / batteries.
Per my home solar project, I needed a method to collect data from both my batteries and inverters, in near-real-time, with no dependency on the internet.
Since, my inverter's connection relies on cloud applications to move data around, I decided to give Solar Assistant a try after reading of its support for the solark-12k.
