Building a NanoPi Cluster - Part 1

A new Project I recently started is to build a cluster of ARM-based hardware. First of all I searched for some suggestions in the web and spent some thoughts on the Hardware I want to use to build the cluster. Most Articles and How-Tos are based on the Raspberry Pi. Nice, but not what I want, too convenient. ;-)

My choice is the FriendlyArm NanoPi NEO, equipped with a Allwinner H3, Quad-core Cortex-A7 CPU, 512MB DDR3 RAM and a Ethernet-Port. Thats all I need.

The Hardware

Nanopi NEO

As the NanoPi NEO is the SBC of my choise here are the specs:

See NanoPi Neo Wiki for more details.

Other Parts

In addtion to the NanoPi there are some more parts a cluster needs:

The Shopping cart

Here is a list of all parts used to build the cluster.

5 Heatsink for Nanopi
1 PowerPort 6 Port, 60W
1 Network Switch 5 Port
5 MicroUSB cable 0,3m
5 Network cable 0,5m

Overall costs: ~220 €

Building the Hardware

Since I dont want to have a nice and fancy enclosure, putting all parts together is pretty easy. Stack all NanoPis with the spacer and bolt them together.

Some double sided glue strip, some cable tie and plugging cable into the correct ports and the Hardware is done! Not that nice, fancy enclosed cluster, but a charming, open air nano-datacenter.

In the next part I write about the system setup process and how to install docker.
