Guest pvong Posted June 3, 2008 Posted June 3, 2008 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
Guest Rich Posted June 3, 2008 Posted June 3, 2008 RE: Dual NIC education 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).

Guest Chris D Posted June 3, 2008 Posted June 3, 2008 Re: Dual NIC education 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.

Guest Chris D Posted June 3, 2008 Posted June 3, 2008 Re: Dual NIC education Best thing to do is have a read of the help file sin the vendors teaming software. I've found these very good.
