Exchange 2010 with SAN replication

Dear All,

  I am confused with the exchange 2010 dr design. Please kindly help to get some clues. Thanks

  I know there is DAG for exchange 2010 DR but we would prefer SAN replication than exchange DAG if the design works. Below is the description of our existing exchange 2003 DR.

  I have 2 sites, 1 production and 1 dr site with SAN replication for exchange dr. For existing running exchange 2003, I setup an exchange 2003 and Domain controller at production site first with physical servers. Then, I setup a secondary dc at dr site also with physical servers. I disconnect the AD replication of 2 sites and setup another exchange 2003 with same server name, ip, configuration at dr site. After finishing the configuration, I shutdown the new exchange 2003 and continue the AD replication between 2 sites with SAN replication for exchange databases. Basically, that's our design for exchange 2003 DR design and we have tested it works. When the exchange 2003 failed at production site, I just start up the server at DR site and mount the database at the SAN to function.

  But I know that the rely of AD in exchange 2010 had been changed a lot. I would like to ask if this would work at exchange 2010 too?

  Thanks to all. I really appreciate if can get any response as soon as possible. I am really struggling with this.
