Sounds more like a Clustered NFS solution to me? Would I be on target with

The client provides the interface so that when a user does a read
or write, it translates the commands. The server takes care of the layout
and locking (if supported). Right now you can have a linux box access
the shared filesystem, but you still need an Irix box to take care of
the metadata and locking.
I have not worked with CXFS, so I might have exact terminology wrong
but I think I have the idea right.
