Failover/high availability file server?

Question

Active Directory

Good afternoon, does anyone have experience deploying a failover file server for roaming profiles?
The idea is that if conditionally one disk / server is naughty, the path to roaming profiles is still available (this is necessary for a terminal farm)

Answer 1

protection against a naughty disk - RAID (mirror)
protection against a naughty server - a cluster
do not mix different functionality (next to critical) on one machine, it is good practice in principle to allocate storage to a separate machine, preferably ready-made hardware aka NAS

Answer 2

I used Storage Spaces Direct for exactly the same task.

Answer 3

Cluster or dfs.
