Yes I am using XFS + highmem on a PE2500 with 200GB of raid 10. The
initial tests I did were done with kernel.org kernels but they failed very
fast after putting some load on the box (local not NFS).

The box is running 1.1 release at the moment and before that the 1.0.2
release. These kernels are based on the original Red Hat Linux kernels but
with XFS included. Since Red Hat also tests their kernels to death on all
sorts of boxes I feel better using those.
Although the machine the machine uses XFS we did purchase the Red Hat
Linux disks with the machine. That way support know it's running Linux.

The NFS load that we have is relatively low but it works well. What I am
really looking forward too is the tg3 driver for the broadcom cards to be
