In all MDIS redundant Servers, the standard Redundancy Objects as described in Part 4 and Part 5 shall be supported. In addition, depending on if the data is identical on the servers the following apply:

On Servers where all data is identical: The server pair shall support either TRANSPARENT_4 redundancy or HOT_3 redundancy or HOT_AND_MIRRORED_5 redundancy including all associated objects and behaviours as described in Part 4 and Part 5.

• On Servers where not all data is identical: The Server redundancy type cannot be specified and redundancy support shall always identify as NONE_0.

In both cases the ServerArray in each Server in the redundant set shall list the URL’s for all other Servers in the redundant set.
