Using DFS 4.1 to add Drive Space

In using DFS 4.1 on a Windows NT 4 SP6 server I was under the impression you
could virtually increase disk space through a DFS share.

My question is: I have a DFS share called
\\%servername%\dfs\data which points to \\serverA\Data. When addingthe second server \\serverB\Data to the same
DFS share \\%servername%\dfs\data this takes a more load-balancing effect rather than a disk space increase. Can you point (1) DFS share to (2) servers and have all files seen by everyone, or do I have the wrong impression.

Thanks for the help
