Configuring Volume Advisor Movement
Recommendations
Volume Advisor can recommend moving a volume to a different Storage Center to improve performance and/or alleviate high
storage usage for a Storage Center. Volume Advisor is configured using threshold definitions, which generate recommendations
along with threshold alerts when error thresholds are exceeded. Volume movement recommendations are calculated based on
the current capacity and past performance of the available Storage Centers.
Threshold Definitions That Support Volume Advisor
Four types of threshold definitions can trigger an alert and a recommendation to move one or more volumes.
