it sounds strange, but I really like booting storage servers diskless.
that is, have their OS state exported from some other machine, so all
the disks in the server are purely data disks.  this offers some nice
properties when reconfiguring machines, even tolerating some kinds of 
failures.  I note that this is how HP configures their SFS (product 
based on Lustre.)
