I have recently set up a single hyper-V host with two guests VMs. The host is a HP Proliant DL380 G9 with 4 SATA drives in a RIAD 5 configuration, one drive being a hot spare.
One server is a DC and also contains a SQL (EXPRESS) database and a virtual disk is attached which contains all of the user files and documents. The 2nd server is an RDS server.
I was thinking of adding a 3rd virtual server as a second DC.
My question is how do I increase the resilience of users access to their files. Can I someone duplicate the files across 2 servers or is this where a separate storage array comes in?
