BES v5 topology advice needed
Please Login to Remove!
Exchange 2003/2007, 1000+ users, spread across european mail servers.
BES machine are Virtual on VMWare.
It has been proposed that we set up BES v5 as follows:
2 Standalone BES servers, each with a copy of SQL 2008 installed. Then use SQL-mirroring and BES-HA to take care of the rest. ie. BES-A with all 1000 users on it, running all the BB services and using a Config DB located on BES-A. BES-A fails and it switches to BES-B, which should, in theory, be a copy of BES-A
My thinking is:
Two BES servers, pointing to a SQL 2008 Config DB on a seperate 3rd server. Split the users across the two BES servers.
My question:
Can anybody give some advice, pros or cons, or alternatives please. Our experience is limited to a single BES, so anybody supporting multiple servers would know more than we do at the moment.
