Otherwise I'll tell you to get a 10Gb switch and build a five node CEPH cluster. :-)

- antongribok 5y agoAfter many years thinking about it and procrastinating, I finally built a Ceph cluster with 4x Raspberry Pis (8GB RAM, 4 or 5 TB external portable drive for each Pi). The setup per node is super simple, Ubuntu 20.04, install Docker, and then one command to add the new node to the cluster, and one more command to add a disk. (Ceph version 16 switched to cephadm for deploying and managing a cluster and it's a lot easier now than with previous versions.) With just 4 nodes I'm already saturating a 1Gb connection on my client (Ryzen desktop). Perhaps the most surprising thing for me was how stable and forgiving a native CephFS client is on my Linux laptop. After waking up from sleep, it takes about a second to reconnect. This weekend I'm planning on expanding to 7 nodes. With 7 nodes total power usage should be ~31 watts (not counting network switch), which is less than my current 6 disk ZFS RAIDZ2 setup in my desktop.
