Hardware

onpit is software that runs on real hardware on your own network. We put that hardware together and deliver it with the stack ready to run. If you prefer to build it yourself, the parts list is open.

onpit runs on real hardware on your network. We put together what fits and deliver it with the stack ready to run, or we set onpit up on hardware you already have.

Where we are right now

The onpit prototype has been running on a cluster of five Raspberry Pi 5 since September 2026. You can't order ready-made devices yet. If you want one, write to us and we'll get back to you as soon as the first batch is ready.

The onpit prototype has been running on a cluster of five Raspberry Pi 5 since September 2026. We put business solutions together individually; get in touch.

Why Raspberry Pi at home

Small, quiet and frugal enough to run around the clock. Five nodes mean that if one fails, the others take over. That is exactly how onpit itself runs.

We are replacing the first generation’s memory cards with NVMe SSDs in every node. They are faster and stand up to constant writes far longer.

Storage is a separate server

The compute nodes and storage are separate devices. The storage server runs OpenMediaVault on Debian and keeps the data on ZFS, which protects every file with checksums. It provides storage to the nodes over the local network, via NFS and as S3 storage, and takes in all backups there. The nodes mirror the live data among themselves; the backups sit apart from them on a separate device.

Existing hardware works too

onpit isn't tied to our devices. The stack runs on ARM64 and x86-64, on Raspberry Pi, mini PCs or servers from Dell, HP, Lenovo or your own build. At least three machines, so that one failing doesn't bring anything down.
