适用于

  • Data ONTAP 8.2 7-模式

解答

  • FPolicy 将导致 CIFS 和 NFS 工作被序列化(不会跨多个处理器核心)。请特别查看启用了 FPolicy 的提升 KaHuna 域利用率。
  • 在 Data ONTAP 7- 模式中, NFS 流量将受到超过 CIFS 流量的影响,因为 NFS 没有等效的 first_read 和 first_write 过滤器。
     for NFS.这意味着将扫描所有读取的数据包,而不是扫描第一个读取操作。(请参见错误 #85682[1]
  • 有关[2]缓解过载 FPolicy 服务器影响的方法,请参见 TR 3640 。
    延迟和请求可以在 perfstat 中或通过 CLI 查看:
    • Data ONTAP 7-模式
      • > priv set diag
      • *>stats perfstat_fpolicy_stats_server (查找 avg_latency 并确保存在非零的“基本”)
