Applies to

 ActiveIQ Unified Manager (AIQUM) 9.7


With the release of AIQUM 9.7 several changes and enhancements went into the headroom calculations. These changes improved the reporting for Performance Capacity Used (PCU).

The changes were:
  • Improved algorithm – Remote traffic was incorporated inaccurately within ONTAP which affected PCU in Unified Manager. 
  • Eliminate gaps in Performance Capacity data seen in Unified Manager   
  • Enhancement was made to bring the PCU data at the 5 minute average as the rest of the counters are for consistency – previously in UM 9.6 it was a one-minute estimate.  

Below is an example of how the PCU and Available IOPs changed after upgrading to AIQUM 9.7.
