Perhaps I'm being overly simplistic, but in this scenario, what would prevent

your example, and all data is available on all machines/nodes.
This solution would limit bandwidth to that available from that single
server. With the cluster approach, the objective is for each machine
in the cluster to primarily access files which are stored locally.
Whole files could be moved as necessary.
Distributed software building faces similar issues, but I've found once
the common files have been read (and cached) by each node, network
traffic becomes one way (to the file server). I guess that topology
works well when most access to shared data is read.
