# Basic overview
- Entrypoint to network is a Linksys WRT1200AC
- Main HP DL380 G6 server
- File server is a Custom Intel SC5000 BASE
# Router
Self assigned WAN IP address, easily probed via our true domain `fosc.etsit.upct.es`
# Main Server
Its hostname is just `fosc`
Runs NixOS with some nice configs and acts as a docker server.
These configs are not intended to be touched by mortals, but can be seen by everyone so they can help in home setups.
Extensive docker-compose setup available at `/var/docker/`.
TL;DR: Go there if you have been given access to deploy a stack.
## RAID setup
NixOS boots from an independent f2fs 250GB SSD. Real storage is available in a ZFS "RAID10" composed of the 4 mechanical disks. Due to RAID card annoyances, replacing a disk requires a reboot (and probably more intervention)
## Traefik
This server is the services entrypoint for the network and hogs port 80 and 443 (among others) and will fetch different webpages based on domain.
## Mounting
Files are retrieved from the file server at `/mnt/gordo`
# File Server
As you would have expected, `gordo`
Also runs NixOS, acts as NFS server and torrent seedbox. Has a minor traefik+docker setup as well, doing not much.
It is basically out of ram 100% of the time, as it is used for ZFS caching.
## RAID setup
Three 1TB SATA disks in raidz (RAID5). The first disk seen by the BIOS contains the GRUB bootloader and a small boot partition aside from one of the three ZFS partitions.
Only one disk can fail at the same time. Be careful out there.
