3DC multi-target configuration with three UR sites

With Universal Replicator, you can set up two secondary sites for one primary site.

The following illustration shows the 3DC multi-target configuration with three UR sites:

  • UR primary site
  • UR secondary site (copies data with a mirror whose ID is an arbitrary number (M in the illustration) from the primary site).
  • UR secondary site (copies data with a mirror whose ID is an arbitrary number (N in the illustration) from the primary site).
NoteIn a 3DC multi-target configuration using delta resync with three UR sites, both the P-VOL and S-VOL of a delta-resync pair are displayed as secondary volumes in the Remote Replication window (Pair Position column).
