| | BES 5 and Exchange 2010 DAG / High Availability
Please Login to Remove!
I'm just wondering if anyone has any experience of implementing a high availability BES 5.0 environment, with Exchange 2010 Database Availability Groups and MULTI DATACENTRE ENVIRONMENTS.
I understand that Exchange 2010 can be multi DC, and that SQL backend can be clustered or mirrored accross DC's, the question I have is around is around the BES front end server. I have read the following document "us.blackberry.com/ataglance/get_the_facts/BES5_High_Availability.pdf" which clearly. I know we have the option of creating a "BlackBerry Enterprise Server" pair and I understand how this would be beneficial for High Availability in 1 DC......but I cannot see this as being a viable solution for multi dc environments, for example you could end up with an Exchange Server (CAS) being and a SQL server working in 1 DC and a BlackBerry Enterprise server running in another DC (this would throttle our WAN links).
Any suggestions (other than SAN level replication)???
