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).
- 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.
