Learning about ZFS and efficiency on my new Arm64 NAS

HL15 with Ampere Altra and ASRock Rack motherboard - NAS fully built

I've been building out a new Arm-based NAS using ASRock Rack's new 'Deep Micro ATX' motherboard for Ampere Altra and Altra Max CPUs.

I posted about the hardware earlier, in Building an efficient server-grade Arm NAS. Go check that out if you want details on the specific hardware in this setup.

But at the end of the build, I installed Rocky Linux, and found the power consumption to be a bit higher than expected—over 150W at idle!

As it turns out, the NAS must've been doing something when I took that initial measurement, because after monitoring it for a few more days, the normal idle power usage was around 123W instead.

The Petabyte Pi Project

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:
