Product:

Storage Analytics 4.2

 

Issue:

The customer noticed that some drives were not reporting correctly and showing abnormally high IOs in ESA. All disk were reporting when viewing through Unity. It appears that the overall lack of significant workload (often less than 5 iops) is leading to the abnormally high/constant Response Time metric.

 

 

Cause:

It appears that the overall lack of significant workload (often less than 5 iops) is leading to the abnormally high/constant Response Time metric.

 

 

Resolution:

ignore abnormal high values of response time when total throughput is very low.
