New price/performance leader for Ethernet switches?

Hi Greg and John,
Thanks for the heads up on this new Intel switch.
Our network runs primarily on HP 2424M's.
The HP spec. sheet indicates a backplane speed of 3.2 Gbps
on the 2424M and 3.8 Gbps on the 4000 & 8000.

We are looking to setup 144 nodes in a FFN design.
The 420T would work perfectly in a 12 switch, 4 NIC's per node arrangement.
At $30 per 10/100 port price, we will have to seriously consider this candidate.


> The 420T has 48 ports and 2 slots which take gigabit expansion cards. It is
> apparently always store-and-forward, but claims 20 usec switching latencies
> for 100 mbit. Street price ( is $1540, the gbit
> uplinks are $377.
> This compares to $1943 for a 40-port HP -- half populated, but that is about
> all the backplane can handle at full speed.
> The Intel switch claims 21 gbits of bandwidth, and that it can run all its
> ports at full speed at any packet size.
> Anyone know of any other new contenders for the crown?
