I am using an HP4000 in a identical format, and am extremely pleased at the
results.  This is one a cluster of Alpha 21164 (533 MHz) with channel
bonding on two NIC's each.  The HP4000 comes with modules for 40 ports, and
can be scaled to 80 ports w/ 2 modules in the rear of the switch for
Giganet/Myranet/etc.  I am running an FDTD calculation involving a per-cell
exposure at the 1mm model level.  I believe it is reasonably close to your
