    Hi everyone!

    Subj.

    I need to have the security of the service in case of a catastrophe with any of the data centers.

    Option
    1. EDGE pool can be one for two data centers and the server can be placed on different data centers? Dns setup round robin?

    If the Data Center A is completely lost,
    will the remaining EDGE servers from site A and EDGE-pool A serve FE-pool B?

    Option

    2. Make a new EDGE-pool B for the second FE-pool B?

    And another question, how are reverse proxies reserved at the data center level (sfb mobility)?

    Lyncdiscover, Lyncdiscoverinternal, etc?

    Thanks for response!

    Hi Renat Burangulov,

     

    If the Data Center A is completely lost,will the remaining EDGE servers from site A and EDGE-pool A serve FE-pool B?

    Yes ,but I suggest you deploy the edge server and reverse proxy for each site for the disaster recovery.please refer to this link

     

    how are reverse proxies reserved at the data center level (sfb mobility)?

    RP was located in the DMZ just like the edge server,it is not belong to the data center level.

    Best Regards,

    Ok, thank u!

    What about DNS external?

    now i have:

    dns-edge
    sip               A       ip edge from site A
    wc                A       ip edge from site A
    av                A       ip edge from site A

    dns-rp
    sfbrp                 A       ip revers-proxy from site A
    lyncdiscover            A       ip revers-proxy from site A
    meet                    A       ip revers-proxy from site A
    dialin                  A       ip revers-proxy from site A


    dns-srv
    _sipfederationtls._tcp  IN      SRV 0 0 5061    sip.contoso.com.
    _sip._tls               IN      SRV 0 0 443     sip.contoso.com.



    After i add a new one edge-pool on B site
    how records should look like: 


    dns-edge
    sip               A       ip edge from site A
    wc                A       ip edge from site A
    av                A       ip edge from site A

    #dns-edge-2 (OK?)
    #sip2               A       ip edge from site B
    #wc2                A       ip edge from site B
    #av2                A       ip edge from site B


    dns-rp
    sfbrp                 A       ip revers-proxy from site A
    lyncdiscover            A       ip revers-proxy from site A
    meet                    A       ip revers-proxy from site A
    dialin                  A       ip revers-proxy from site A

    #dns-rp2 (just as round robin with ip RP-server from A? Will the client understand?)
    #sfbrp                 A       ip revers-proxy from site B
    #lyncdiscover            A       ip revers-proxy from site B
    #meet                    A       ip revers-proxy from site B
    #dialin                  A       ip revers-proxy from site B


    dns-srv
    _sipfederationtls._tcp  IN      SRV 0 0 5061    sip.contoso.com.
    _sip._tls               IN      SRV 0 0 443     sip.contoso.com.


    #dns-srv2 (add srv rec with different weight or? Will the client understand?)
    #_sipfederationtls._tcp  IN      SRV 0 10 5061    sip2.contoso.com.
    #_sip._tls               IN      SRV 0 10 443     sip2.contoso.com.

    In the accident scenario, the total loss of the data center A and the switch to the reserve pool in the data center B

    or I need to add my second names in the topology for the second proxy. Keep them inactive, and in case of an accident switch to them?
    It does not look very good ...

    You donnot need to add the "dialin2.contoso.com" and "meet2.contoso.com",only one URLs is meet the requirement.
