We are currently on a single 5.5 box (in one of our two locations.) Our
company has two locations about ten miles apart. The network connection is a
100mb microwave. About 50% of the users are one either side. Ultimately we
would like to have an Exchange 2003 system in both locations. The natural
way we are thinking is to have the mailboxes at location "B" on the "B"
Exchange Server, and the mailboxes at location"A" on the "A" Exchange
server.
 
This seems fine except my management wants to have some kind of DR plan that
is better/faster than tape. Is there anything built into Exchange 2003 that
will let us do this? Ideally we want a situation where if we lose power (or
there is a planned evacuation) at one of the locations, the mailboxes can be
served up at the other location.
 
 
I do not think clustering is an option as the microwave is not 100% reliable
(its probably 97% reliable) Heartbeat cannot be guaranteed. We do not want
to have random cluster failovers.
 
In our infrastructure is an EMC SAN. We will likely put the exchange stuff
on that. While the EMC SAN has replication (SRDF) I do not think the
replicated data can be used with out a great deal of work. We are also using
Legato Networker.
 
 
 
Anyone out there with an environment and needs like ours? 
 
 
Any help /feedback would be appreciated. The vendor is currently on the
premises and is going to begin the migration in the next several weeks.
 
 
Thanks in Advance.
