Applies to

  • SnapMirror
  • Aggregate-level deduplication
    • Aggregate deduplication
    • Cross-volume deduplication

Answer

  • Aggregate-level deduplication eliminates duplicate blocks across volumes belonging to the same aggregate
  • Aggregate deduplication savings (inline or background / post-process) on a SnapMirror source are not retained by SnapMirror transfers
    • This has no impact to SnapMirror maintaining volume-level storage efficiency savings from the source
  • SnapMirror destination clusters can use aggregate deduplication with type-DP SnapMirror destination volumes
    • This has no impact to SnapMirror maintaining volume-level storage efficiency savings from the source
