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.
Supported Threshold Definitions Threshold Alert Recommendation
Type Alert Object
Type
Alert
Definition
IO Usage Storage Center FE IO/Sec When front-end IO for a Storage Center exceeds the configured error threshold, the
alert recommends moving volumes to a specific Storage Center.
IO Usage Volume Latency When latency for a volume exceeds the configured error threshold, the alert
recommends moving the volume to a specific 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 configured alert
threshold, the alert recommends moving volumes to a specific Storage Center.
Storage Storage Center Percent Used When the used space percentage for a Storage Center exceeds the configured alert
threshold, the alert recommends moving the volume to a specific Storage Center.
General Volume Advisor Requirements
Storage Centers must meet the following requirements to be considered for volume movement recommendations.
Requirement
Description
Management The Storage Center must be added to Storage Manager.
NOTE: Storage Centers that are not mapped to your user account are not presented as
recommendations, but might be presented as recommendations to other users.
Licensing (Storage Center 7.0 and below) The Storage Center must be licensed for Live Volume.
Storage Center version The Storage Center must be running the same version (x.y) as the original Storage Center.
Tier 1 disk type The Storage Center must have the same Tier 1 disk type as the original Storage Center, such as a
7.2K, 10K, 15K, or Solid State Disk (SSD).
Additional Requirements for the Volume Latency
Threshold Definition
The original volume and candidate Storage Centers must meet the following additional requirements to be considered for volume
movement recommendations triggered by the volume latency threshold definition.
Requirement
Description
Original volume configuration
• The volume cannot be part of a replication, Live Volume, or Live Migrate.
• The volume cannot be associated with a consistent Snapshot Profile.
