适用场景

  • ONTAP 9
  • SnapMirror
  • 存储效率

问题描述

  • 尽管卷几乎相同、但SnapMirror目标聚合已达到98%、而源聚合上为71%。
  • SnapMirror关系使用SnapMirror XDP引擎和逻辑复制与存储效率(Logical Replication with Storage Efficiency、LRSE)、从而保持源端存储效率节省。
  • 源和目标之间的聚合效率节省量差别很大:

源聚合:

cluster1::*> df -A -S

Aggregate                 used       total-saved   %total-saved    deduplicated    %deduplicated    compressed    %compressed
aggr1_cluster1_01  24931857788       16729430368            40%     16729430368              40%             0             0% 

目标聚合:

cluster2::*> df -A -S

Aggregate                 used       total-saved   %total-saved    deduplicated    %deduplicated    compressed    %compressed
aggr1_cluster2_01  34579937728               104             0%             104               0%             0             0%
