Can I create a Server module having Storage as a RAID enclosure/ rack ? - build storage server

When I create or expand a shelf with a capacity of, say, 2 TB, you can build a server for Windows NT? or higher? Can I run a network of more than diskless nodes that are connected to the central server? the network is stable and fast enough? What equipment do I need?
