The hardware on which we run our Minestest servers exists of an Intel NUC with an Intel i7, 2.70GHz, 4 cores, 16 GB RAM. We use SSD’s as harddisks. This server runs since april 2019. The former server was also a NUC with an Intel i7 and that one served from 2015 until 2019.
As virtualisation software we use Proxmox. Proxmox is a Debian based open source virtualisation system. Inside each container we use Ubuntu server as Operating system on which a Minetest server can run.
The network we have available is glassfiber with a 100 Mb upload and 100 Mb download speed.
