Hi!
Our customer have 2 datacenters where we will place our exchange servers. Both datacenters are in the same AD site. We are planning of configuring a DAG with 4 servers. We will have a casarray loadbalanced. Should we use the DAC configuration on our DAG? Is there somehting that we need to consider with this setup?

I would implement DAC mode, yes.
Also make sure you are at SP2 RU2 and have also applied:

Thanks A D,
another question, if the datacenter where the fsw i stored goes down. Should we reconfigure the DAG to use a new FSW in the remaining site?
And one more thing, it now seems like we only have money for 3 servers, 2 in one data center and one in the other. Will this work at all? Still struggeling to get money for the 4:th servers but not sure if i will make it.
Regards

See http://technet.microsoft.com/en-us/library/dd351049.aspx on how to activate the other site.
However, if you have only 1 member in the other site, a File Share Witness will not be used and you will have to force quorum on the remaining server.
