适用场景

  • GCP
  • ONTAP 9.10.1
  • 单实例数据日志记录( SIDl )

问题解答

  • 在数据聚合上启用 SIDl 后 ,启用实时重复数据删除或数据压缩将会产生发生原因 性能问题 ,因为 SIDl 需要使用 CPU 周期。
  • 启用 SIDl 后,可以跳过 NVRAM 并仅将数据直接写入磁盘一次,从而提高写入性能。

追加信息

要检查 SIDl 状态,请从集群命令行界面运行命令 aggregate show -aggregate <<aggregate_name>并检查 Enable SIDL 密钥

示例:
::> aggregate show -aggregate aggr2          
                         [...]
                    Enable SIDL: on
                     Composite: false
               Is FabricPool Mirrored: false
              Capacity Tier Used Size: 0B
         Space Saved by Storage Efficiency: 0B
  Percentage of Space Saved by Storage Efficiency: 0%
Amount of Shared bytes count by Storage Efficiency: 0B
          Inactive Data Reporting Enabled: false
           azcs-read-optimization Enabled: false
         Enable Aggregate level Encryption: false
         Aggregate uses data protected SEDs: false
