Exchange 2013 DR Scenario setup RRS feed

  • Question

  • Site A
    1 CAS Server 2013
    2 MBX Servers 2013 with DAG01 (MBX1 holds all active copies and MBX2 all passive copies)

    Site B
    1 CAS server 2013 with FSW 
    Want to add a mbx server here which we will a part of same DAG01 in siteA and will hold passive copies of the DB

    - Steps: Enable DAC in SiteA, Add the IP address of the second subnet in SiteB to the existing DAG01.

    Goal is the if SiteA is inaccessable the users should be able to access OWA and Outlook from SiteB over the internet.

    If siteA goes dud ... I understand there is manual work involved of evicting and removing the server and making sure the DB in SiteB is mounted and Up. MX pointers etc. 

    Bit unclear about the FSW - Will the FSW work or do we need to place the FSW in a third site?

    Thank you

    What do you mean by .... THe FSW only should be in a 3rd site if you want automatic failover and the sites are peers.   

    What do you mean when you say sites are peers?

    Equal. in Other words, you dont care where the databases are active, both data centers can handle clients at anytime. If you want to activate the second site in a DR scenario only then would not want a 3rd DC for the FSW.

    If you want to activate the second site manually then follow:
