Look to the specifications of the network card. Adaptec has had a four port
10/100 network card (since before the gig cards came out). The Adaptec card
allow you to aggregate the bandwidth across 12 ports (1.2mbps full duplex)
or you can do a combination of port aggregation / fail over. I.E. use two
ports for combined bandwidth to one switch, two to the other and use one to
either load balance or fail over. The down side is that you have to have as
many ports available on your switch(s) as you have ports in the server.
Good luck,

Hi,
Where is your most likely point of failure or is bandwidth the issue. WIll
etherchannel work to the 2NICs. I don't know that the NT server will
understand Etherchannel.
In a study I did recently I found in a network that all the user areas went
to a "main core switch". The servers had two NIC's each going to a separate
switch. The "backup core switch" plugged into the main switch. There was
still a single point of failure to the users "the main core switch". Should
the "main core switch" fail there would be no network. The redundancy only
covered the NIC's in this case nor did the second NIC provide any load
sharing.
Just some thoughts.
