  • Question

  • Hi all

    I have SBS 2011 installed and configured.

    I need to setup DAG as i setup a new windows 2008 R2 with exchange 2010 on it.

    IS it possible?

    Does the SBS 2011 come with enterprise edition of windows?

  • DAG stands for Database Availability Group and is a technology
    introduced in Exchange 2010
     
    To answer the OP's questions
    SBS 2011 which has Exchange 2010, comes with Windows Server 2008R2 Std
    Edition
     
    It would be a very high cost to a small business to add a second Server
    running Exchange and Windows Server for the purpose of Failover of email
     
    Since Exchange (except with SBS) is not recommended to be installed on a
    DC, it would seem that you'd need another Win2k8R2 to act as a DC if you
    are trying to get full "failover" capability
     
    I'm not aware of any limitation for Exchange on SBS being part of a DAG

  • Yes what is DAG? If you mean SBS 2011 it already has Exchange so why are you installing a second server with Exchange?

  • Dear

    Can i setup scr with sbs 2011 and another win 2008 r2 with exchange 2010 on top of it?

    I heard that database copy in exchange 2010 is like scr in exchange 2007.

  • An Exchange DAG requires a cluster (AFAIK) so you need 2 machines >=Windows Enterprise. (Standard will do it in 2012)

    SBS cannot participate in the cluster, so the DAG could be part of an SBS based Exchange Organisation, but not include the stores on SBS itself.
