Workloads in Active IQ Unified Manager

KThomsen

Does applying Performance Service Levels in Active IQ Unified Manager actually change anything on the storage array side, i.e. applying QoS to volumes/LUNs or does it merely tag the volume/LUN in AIQUM for its analysis or the workload?  The documentation is anything but forthcoming on this point.

No, It does not.  AIUM/OCUM only provides "QoS policy group" analysis and recommendations. The QoS can only be applied via System Manager/CLI or using automation tool called "WFA".  AIUM will only display the pre-defined QoS policies that you have defined on the ONTAP itself. Yes, you can create user-defined policy and attach it to objects for viewing their IOPS/MBs performance to get an idea on how they are actually doing. However to stop them (ex-vol/lun) from consuming resources, you will need to apply it on the OTNAP itself.
