We are about to embark on a storage consolidation of both SAN and NAS shares. SAN part would be easy but I am more concerned about the NAS consolidation. Currently we have about 5 windows 2003 servers working as File Servers hosting amongst them about a thousand file shares serving around 2000 users. management of these file shares on daily basis using base Windows 2003 OS for granting permissions/access on daily basis is also a nightmare.
I was reading Microsoft's IPD document ( http://www.microsoft.com/downloads/details.aspx?FamilyId=AD3921FB-8224-4681-9064-075FDF042B0C&displaylang=en
) and realised that DFS is the new way to go. Are there any gotchas? Would the migration be easy? Our new NAS head is a high IOPs hitachi system on which we want to cosolidate everthing.
