Conguring Volume Advisor Movement
Recommendations
Volume Advisor can recommend moving a volume to a dierent Storage Center to improve performance and/or alleviate high storage
usage for a Storage Center. Volume Advisor is congured using threshold denitions, 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 Denitions That Support Volume Advisor
Four types of threshold denitions can trigger an alert and a recommendation to move one or more volumes.
Supported Threshold
Denitions Threshold Alert Recommendation
Type Alert Object Type Alert
Denition
IO Usage Storage Center FE IO/Sec When front-end IO for a Storage Center exceeds the congured error threshold, the
alert recommends moving volumes to a specic Storage Center.
IO Usage Volume Latency When latency for a volume exceeds the congured error threshold, the alert
recommends moving the volume to a specic Storage Center, and gives you the
option to act on the recommendation by creating a Live Volume.
IO Usage Controller CPU Usage When CPU usage for a Storage Center controller exceeds the congured alert
threshold, the alert recommends moving volumes to a specic Storage Center.
Storage Storage Center Percent Used When the used space percentage for a Storage Center exceeds the congured alert
threshold, the alert recommends moving the volume to a specic Storage Center.
