If you are running on Linux (or can tolerate one or two Linux machines
to front your fileservers) look at ipvs (stands for IP virtual server)
and things built on top of it, e.g. piranha?

The ipvs kernel modules will redirect incoming connections based on
policy and weightings for the real servers, and you can use monitoring
scripts to tune the algorithm dynamically based on observed load,
availability etc.

Some careful network and samba config will probably let you use your
existing file servers as the ipvs routers, with failover, etc. if they
already run Linux. Definitely an exercise for the reader though!
