Hello,
I am new to the virtual computing world. I plan to replace various computers, each with their own data, with a central server(s) setup. I would like to do a single EXSi server with various virtual servers running inside- those include:
-NAS
-XBMC (application server)
-Windows (terminal server)
-Linux (various dist.) (terminal server)
For all computers in the house outside of the main (most power hungry) computer being simple thin clients.
I am worried however about the reliability and ease of use surrounding running a virtual NAS. I am unsure how stable the setup will be, since i plan to connect to an outside array for storage. I would rather not have a single array for the entire ESXi server.
I am trying to contain everything in one server to keep electric costs down and not have my server room (closet) putting out more heat than the AC can combat (exageration, i admit).
I am new to the the virtual world, so be gentle. 
Thank you,
Terry
