Bit broad question but Sounds like a nas can be a way to go. Read up on raid and think about your backup strategy first.
(I use a synology nas with 4Tb disk at home that backups to an offsite readynas with 4x 4tb disks in raid config and encryption)
Guilty too. There are names on router- and switch interfaces. Servers get fixed IP from dhcp so is in the note field there too. That’s about it
Thnx! This looks like the way to go.
