Hi!
I am looking for some recommendations as to which direction to head in to expand my current Exchange system.
Currently I have a 2 server DAG, 1 physical, 1 virtual, with a separate virtual CA/HT server (different VM host) all within our office.
The requirement is to have a full working server offsite in case of disaster affecting our physical building. The datacenter will be connected via 100mbs private LAN.
Currently the DAG server 1 hosts live databases A and B. with copies of C and D.
DAG server 2 hosts live databases C and D along with A and B copies.
My plan was to have the new remote Exchange 2010 server host copies of A,B,C and D as a third member of the DAG. Optimally I'd like to have the CA/HT roles reside on that server as well, but also act as a fail-over in case the local CAS is down.
I remember in my studies of Exchange 2010 CAS arrays that multi-site needs to be treated differently in case the link fails and you have 2 live copies on different sites, so I need to take that into consideration.
Also, can I install just the DB server role for now to get the data replicating offsite and worry about adding the CA/HT roles to it later, or am I asking for trouble?
Everything works beautifully right now, I just want to expand to the DR site without breaking it.
Exchange 2010 SP2 on Server 2008R2 Ent
Thanks,
