Hi All

I have a question.

1. If destination site SP was out of order, Is the production site  fall into failover ?

    yes if one SP fails then the peer SP takes over its services

    Please see the Unity High Availability White paper for details

    not sure I understand what you mean

    you are showing two Unity systems - they are Independent of each other

    just because on Unity1 SPA failed over to SPB doesnt cause a similar failover on Unity2 and vice versa

    無題1.pngHi

    This image mean the Unity replicating from production site to destination site.

    ----environment------

    NAS Server1 is SPA

    NAS Server3 is SPB

    NAS Server1(owner SPA)→Dest_NAS Server1(owner SPA)

    NAS Server3(owner SPB)→Dest_NAS Server3(owner SPB)

    ------------------------------

    I want to know below.

    For example.

    When destination site SPA was out of order, will production site SPA is failovered ?

    no - there is no reason for that
