They were called SAN before the cloud became popular. 

I now have a box called "personal cloud" which is about the size
of the usual extenral USB hard drive, but with ethernet instead
of USB connection. Internally, it runs linux (you are allowed
to ssh into the box). Otherwise, it run the usual file sharing
protocols. I mostly use NFS, though SMB is probably more popular.
