Prerequisites for 3DC multi-target

  • At least one storage system at the primary site, TC secondary site, and UR secondary site.
  • If you set up the 3DC multi-target configuration by using VSP G1x00 or VSP F1500, any combination of VSP G1000, VSP G1500, VSP F1500, VSP, USP V/VM, VSP G800, VSP F800 can be used at the primary and secondary sites.
  • If you set up the 3DC multi-target configuration by using VSP Gx00 models or VSP Fx00 models, any combination of VSP G800, VSP F800, VSP G1000, VSP G1500, VSP F1500, or HUS VM can be used at the primary and secondary sites.
  • When managing the storage system with CCI only, CCI is recommended at all sites.
  • When managing the storage system using HDvM - SN, Device Manager - Storage Navigator is required at all sites.
  • The primary site requires the following:
    • TC
    • UR
    • TC P-VOL = UR P-VOL. This is the primary production volume.
    • UR master journal volume
  • The TC secondary site requires the following:
    • TrueCopy
    • TC S-VOL
  • The UR secondary site requires the following:
    • UR
    • UR S-VOL
    • UR restore journal volume
  • 3DC multi-target can be used in configurations with multiple primary and secondary storage systems. However, delta resync configurations are not supported in configurations with multiple primary and secondary storage systems.
