Install
Do a basic Arch install with the hard drives software raided in RAID 1, all of the device as /
Make sure to install GRUB to ALL of the drives and NOT /dev/md0 - also protip: md0 is a partition, not strictly a block device, thus it does not need a mbr and you can mkfs.ext4 /dev/md0 without issue :D
Install Packages
pacman -Syu htop iotop iftop lm_sensors vim sudo qemu libvirtd screen rsync tmux p7zip
Change SSHd to use port 13699 in addition to port 22 (add a line below Port:22 with Port:13699). Edit

Warning! This requires setup on the managed switches it's connected to!
