问题描述

针对 SolidFire 存储卷报告了高延迟。这种情况可能会以不同方式出现。
 
  • 如果您使用的是 VMware , [1] 则会在Monitor>Events中显示消息 "performance has detered" :

  • SolidFire Active IQ( AIQ )Volumes中的 >>>> 下Active VolumesActionsView DetailsLatency,您将发现延迟值高于预期值。

  • 在 Element UI 中的Reporting> 下Volume Performance,您将发现延迟值高于预期值:

  • 在高延迟期间,您还会注意到,根据设置的最大 QoS ,吞吐量正在达到其最高峰值。以下示例显示了 QoS 最大值 15 , 000 IOPS ,最大吞吐量为 100 MB/ 秒,但从整体集群性能来看,此值相对非常低。      clipboard_ebcf8fc59e708da82ed6892e2f088070d.png集群整体性能显示几乎没有达到 5%clipboard_e66fd32446871c11abefcc61b169a1640.png
