适用于

  • ONTAP 9
  • FlexGroup

问题

  • 在 FlexGroup 父级上观察到 "其他"操作（特别是 READDIR，但可以在 GETATTR 和其他元数据操作上看到）的延迟增加
  • 写入吞吐量可能似乎小于总吞吐量
    • 示例：通常，6 节点 A800 集群在达到 Data Processing 延迟之前可能会看到 10 GB/s 的写入，但写入的吞吐量可能仅为 1-2 GB/s
  • 在单个组成部分上可以看到延迟
  • 当单个组成部分内的读取/写入工作负载大幅增加时，读取或写入可能会显示延迟大幅增加。
  • 延迟被视为 Data Processing 或 Data 在 qos statistics volume latency show
  • 如果多个目录被读取或写入，延迟可能在组成卷之间快速连续转移
