Dito for the bus. A standard PCI bus has a maximum throughput of ~1Gbit/s. With 200
Mbit/s for each full-duplex 100 Mbit/s
NIC this totals to a maximum for 5 NICs per PCI bus. For higher throughput you'll
need multi-bus systems like the Sun E250,
E220R, E420R (all 2 PCI busses: one standard, one double-clocked) or the Sun E450 (six
PCI busses).
