Dual NIC education

I'm a newbie so please explain.

I got a couple of servers running running w2003 with dual NICs. I'm trying
to figure out how to use the dual NICs.
1) Do you guys assign different IPs to each NIC? If so, do you make two
different A records for the same server except with two different IPs?
2) Even though each NIC has it's own MAC address, can I assign them with the
same IP number?

Basically, I'm trying to see if can use both NICs at the same time. I don't
understand if some request information to an IP and I have 2 NICs with the
same IP, will the request happen twice? This would create overhead.

Please educate me like I'm a newbie who just started working with this
stuff.

Thanks!
Phil
 
Depending on the manufacturer what it's called will be different, but you can
set up a virtual NIC, which is really just the two NICs teamed together for
load balancing or fault tolerance, whichever you prefer. then you just put
the IP on the virtual NIC.
the info will either load balance between the 2 NICs or just go to the one
(if going with fault tolerance).

It also depends on which switch/switches you are using as to what type of
teaming you will get. The Nics need to be plugged into the same physical
switch unless you have a stack of switches which act as one physical unit.

If you plug each nic into a different switch you'll end up with problems.
Then dependent on your actual switch you will get either 1 nic receiving all
data packets and both sending data or both nics sending and receiving. This
is all dependent upon your switches.

They can also be configured as basic failover but you may as well utilise
the extra bandwidth and have the failover aswell.

If yout team the NIC's they need to be either plugged into the same switch

Thanks guys! Have any idea where I can find some simple learning
instructions about this on the net?
Thanks!

Best thing to do is have a read of the help file sin the vendors teaming
software. I've found these very good.
