Hi dear,
The geographic redundancy solution protects systems and data from
disasters through geographic isolation by building and maintaining a backup
system remotely. The dispatching system (eMDC+eUDC+eMRS), eOMC, and eCN (eCNS
or eSCN) support geographic redundancy in co-deployment mode or
independent-deployment mode.
Note:
1. Geographic
redundancy of the dispatching system applies to the eUDC, eMDC, eMRS, and eOMC
deployed independently. In this scenario, the eUDC needs to be configured with
a separate heartbeat link.
2. Geographic redundancy of the dispatching system does not apply to
the following scenarios:
l Co-deployment
of the eMDC, eUDC, and eOMC
l Rapid, ECV,
or fixed single station
