Hi

I have recently installed Exchange 2010 and with CAS array.

I have been questioned to configure CAS array between sites. i.e (Node a on site 1 and Node 2 on site 2) and between these two nodes CAS array to be created.

Is it possibel to do such configuration. Kindly suggest.

Also pls share some documents or links which can explain me such sonfigurations.

Thanks

A Exch 2010 CAS Array is AD site specific. Meaning that you cannot have CAS servers from two different AD sites in the same array and you cannot " stretch" a CAS array across multiple AD sites. In your case you would have to create two CAS arrays (one for each site) or collaspe your AD sites into one (but I am not recommending this since I know nothing about your infrastructure). Here is some more info:

Hi,

Exchange CAS Array is AD site Specific. So you will not be able to configure Node 1 in Site 1 and Node 2 in Site B.

Below is the links for steps and recommendation for configuring Exchange CAS array.

Another blog on the same CAS Array is also posted. This might also help you.

Hi,

Exchange CAS array is AD site Specific, so you will need to have the CAS servers in the same AD site to create CAS Array. Once you hav created CAS Array for AD site then automatically when you add addtional CAS server it gets added to Exchange CAS Array, if it is in the same AD site. In your present situation, you will have to place both the CAS server in the same site either in Site 1 or Site 2.

For more info refer:
