We don't have FC yet, though we're thinking of moving that way when we
upgrade the libraries.  In any case, were taking a measured,
incremental approach to our upgrade path, so that we don't change too
much at one time.  

We also have a bigger site with a F980 cluster and a F960 as well,
which has close to 45Tb of data to backup.  That's our problem child
currently.  :]

I may not have spoken clearly.  Currently, we mount our filer(s) to
our backup servers via NFS and just backup those filesystems.  We have
to specify them by hand and run scripts regularly to make sure we're
not missing any.

We have no deployed any storage nodes, though it's tempting.

In our environment, I won't do Windows as the primary server, were a
Unix/Linux group.  I'd think about RHEL3/4 StorageNodes though...
