与源聚合相比、SnapMirror目标聚合的容量更满
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%
