Creating a DAG on Exchange 2010

Hi,
I'm creating a DAG on Exchange 2010.
My question is about the IP address I assign the DAG.
The servers have two Network cards in them.

Server1
Public: 192.168.100.72
Private: 10.235.10.10

Server 2
Public: 192.168.100.73
Private: 10.235.10.11

I know the correct thing to do is set up the DAG so the network traffic for replication isn't happening on the public side.

So  ...
when I assign an IP address to the DAG using something like this:

Set-DatabaseAvailabilityGroup DAG1 –DatabaseAvailabilityGroupIpAddresses xx.xx.xx.xx

Is this where the Network that will carry the replication data is set? So, in other words, should I make the IP address for the above command something like 10.235.10.12 OR 192.168.100.74 ?

Thanks
Mike

The IP should be whichevere network your users are not on....

Although.... (not a best practice suggestion here!)... it can be overriden so both users and replication are on the same subnet, but I wouldn't.....

it could be anything but needs to be accessible wthin DAG members (exchange servers)

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Can I change the IP assignment for the DAG down the line? I'm talking to the company who is hosting my server and they need to install another NIC for me.  Once they do that I will have to change the IP of the DAG. Can I set one IP now and then change it again later or will I need to rebuild the DAG from scratch?

Thanks
Mike

You can change IP of DAG later on, if needed. But the DAG IP from the production range, 192 in your case.
