This week I finally moved my gaming/Linux PC into my little office rack—it's that 2U box above the UPS at the bottom:

I remembered seeing Linus Tech Tips' 4U build in a video a couple years ago—but he has a full 42U rack in his basement. I don't have that much space—just 2U (technically 3U if I wanted) in my little under-desk studio rack.

So after working with them last year on a similar build (but with a prototype case), I got in touch with MyElectronics and they sent over their new production Mini ITX short-depth 2U PC case.

I haven't had time to write up the details yet, but I wanted to share a project that's been many months in the making: The Petabyte Pi Project on YouTube.

I'm still doing follow-up testing based on feedback from Broadcom storage engineers, and will put out a much more in-depth blog post later, but the gist is:

Can a single Raspberry Pi cosplay as an 'enterprise' storage server, directly addressing 1 PB of storage?

Now... caveats abound here. What does 'enterprise' mean? And what does 'directly addressing' mean? Those things are all answered in the video linked above.

But to give a tl;dr: The Pi does not perform swimmingly. But... I did get a single array of 60 hard drives—20TB Exos HDDs to be exact—working in a 45Drives Storinator XL60 chassis, controlled only through a single Raspberry Pi Compute Module 4. Of course I had to rip out the Xeon guts and replace them with said Pi:

tl;dr: This website is currently being hosted off-grid, on a cluster of Raspberry Pis, via 4G LTE—or at some points through the same tunnel via WiFi if signal strength gets too low. Here's the GitHub repo for the project.

Note: The website was down for a few hours this morning, as shortly after this post I started getting a 40-50 Mbps flood of POST requests (over 6 million in a 30 minute time frame)... and yeah, no way the little Pi cluster could handle that. Thanks, Internet. It's back up through Cloudflare now, and I'll post more on this 'fun' experience later.

A couple weeks ago, after months of preparation, I took my 4-node Turing Pi 2 cluster (see my earlier review) to my cousin's farm, and ran this website (JeffGeerling.com) on it, live on the Internet—completely disconnected from grid power or hard-wired Internet.
