Bridging in windows 2008

Links to resources with information about technologies that are closely related to DCB, or otherwise relevant to DCB are also provided. Latency mitigation, see Low Latency Workloads Technologies. DCB provides hardware-based bandwidth allocation to a specific type of traffic and enhances Ethernet transport reliability with the use of priority-based flow control. Priority-based flow control is essential if the upper layer protocol, such as Fiber Channel, assumes a lossless underlying transport.

In general, FC hardware is significantly more expensive to deploy than the Ethernet hardware, which results in large capital expenditures. See the following subsection for information about how to disable them. So here is my question - I know that the benefits of bridging are the joining of two subnets via the bridge and logically if there is only one subnet and by the fact that you have two active NICs then you have fault tollerance, but is there any reason why you would not enable a bridge within the same subnet?

You cannot bridge different subnets. Bridging can only connect two segments which use the same IP subnet. To connect different subnets you need to use IP routing.

ICS does not work with AD. Note that you should not run your DC as a router. Two active NICs do not give you fault tolerance if they are in different subnets as in a router and they will cause all sorts of odd problems if they are in the same subnet unless you use NIC teaming.

In my opinion, a lot of time is wasted trying to avoid something which isn't really worth the effort. Thank you for your post here. It split the conflict domain instead of the broadcast domain. If you add a layer 2 device in a broadcast domain already with a Switch, broadcast storm which you will never expect may happen. Is it safe, or ok to bridge the NICs on this type build? Anyone have any experience or advice as to why not to do it?

I can't say that I've ever used bridging to increase network bandwidth, that essentially allows the server to have two interface cards act as one, but not neccisarily having them do the same task.

Maybe I'm wrong, but that doesn't help with performance much. Now, NIC teaming is probably what you want to do, that allows for two NICs to do the same job and should increase bandwidth on servers. Teaming won't increase your speed on the Internet, just on the LAN. It also allows for fault tolerance.
