I plan to install a NethServer 7 server at home on a old Sophos UTM 425 Aplliance. The problem is that I’ll need some storage space and this Appliance is limited to two 2.5’ hdd. I think it’l be sheeper to get a NAS and mount it in Nethserver for fil sharing and nextcloud. What will be the best option for that? ISCSI? Is it possible?
