This is a development and test VM Ware server, so it hosts lots ( 100
or so) of test VM with sparse image files (when you start a VM to host
a quick test, you don't want to spend 15 minutes initializing the
drives).

The application write strategy is as simple as possible; several
different machines unaware of every other write huge media files to a
samba share. I don't know how it could be worse, however it could
hardly be enhanced in any way.
