适用场景

  • NetApp Element软件
  • NetApp SolidFire
  • NetApp HCI

问题描述

  • 可以 通过不同方式观察到针对SolidFire存储卷报告的高迟交情况
  • 如果您使用的是VMware,则  [1] 会在 Monitor >中看到消息“性能已下降” Events

  • SolidFire Active IQ (AIQ)中的 Volumes  Active Volumes    >>>>下ActionsView Details Latency 、您会发现延迟值高于预期:

NetApp Element软件

  • 在Element UI中的 Reporting >下、 Volume Performance 您会发现延迟值高于预期:

NetApp SolidFire

  • 在高延迟期间、您还会注意到 、  根据 设置的最大QoS、吞吐量正达到其最高峰值。以下示例显示了QoS最大IOPS为15、000次、最大吞吐量为100 MB/秒、但总体集群性能相对较低:

NetApp HCI

  • 集群整体性能几乎没有达到5%
