Intro & Specs
Hello and welcome to the Turing Pi V1 documentation.
Turing Pi V1 is a 7 nodes cluster on a mini ITX board. It’s a scale model of bare metal clusters like you see in data centers. The Turing Pi board can be used as a local mini server to host apps, containers, Kubernetes. The Turing Pi also is a great tool for learning cloud-native technologies, Serverless, Microservices on a bare-metal cluster. The Turing Pi top/main node can act as a NAT/Router for the rest of the nodes. If you move the cluster from one location to another, all the node's IPs stay the same.
Some of the Turing Pi V1 features:
- Flash mode - flash RPi compute modules using the Turing Pi board
- Boot mode - boot OS through eMMC or SD card or netboot
Please note, you can use either eMMC or SD card storage. You can't use both options.
- Power management for each node (on/off/reboot)
- Real-time clock (RTC)
- I2C cluster management bus
- Compute modules hot-swap
