3 DC each with 3 NICs , how efficient is NIC trunking??.

I've three Windows 2k Advanced Server DC , each DC has 3 NICS. Can I assign
the same IP address to all 3 NICS on each DC and use it as a trunk.
Without putting the three DC in a cluster.... . Just NIC teaming and not
clustering. What's the steps???
Would it be better than just sticking a Gigabit ethernet card in???
 
Hi Joe,

Why would you liek to use 3 NICs on a DC? What is the speed of each NIC?

NLB is the solution to create a virtual IP address, but it os not a
solution for DCs.

How many clients dou you have in your environment?

Regards

It is possible if the NIC manufacturers offer the software to do so. We use
Intel Pro 100 NIC's and all our servers have 2 in which act as 1 using Intel
Proset, So they can send and receive on either card which increase bandwidth
to 400Mbps. I know Broadcom and Compaq offer similar software.

The rules are the cards have to be connected to a switch and depending on
what the switch can handle there are various options available such as
adaptive load balancing etc.

I know with the intels that they have to be in multiples of 2. I.e 2 or 4
NIC's

Gigabit NIC's will be better although you lose the redundancy if you only
have 1 NIC

Hi Jose, I got three Win2k Advanced Server DC, each DC has three 10/100
network cards. (Not important to discuss: these DC are our Lotus Domino Mail
servers that can replicate with each other in the same subnet/even in
different subnet and cause huge amount of traffic on the NICS). I use 3 NICS
to improve performance of transfer speed and also wanting the NIC teaming
load balancing redundancy functionality. At the moment I assigned each NICs
an ip address from a different subnet of 192.168.100.2 255.255.255.0,
193.168.100.2 255.255.255.0, 194.168.100.2 255.255.255.0. It works but the
problem is because of the three different subnet , there's three different
broadcast domains and the network and Cisco router seems to slow down. I
was thinking of changing the methodology by combining the three NICS
teaming functionality and moved them back into the same subnet of
192.168.100.2 255.255.255.0 , in this way I will have only one broadcast
domain, and presumably come back to the original fast network state. NIC
teaming looks promising to me. But I've got three DLINK DFE-528TX Nics and
don't know if they support NIC teaming and don't know if the NLB feature of
Win2kAdvanced server can trunk these NIC teaming with just one ip address
with putting the DC into a cluster????
