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.

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.

10K, 15K, or Solid State Disk (SSD).
Additional Requirements for the Volume Latency Threshold
Denition
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 denition.
Requirement
Description
Original volume conguration
• The volume cannot be part of a replication, Live Volume, or Live Migrate.
• The volume cannot be associated with a consistent Snapshot Prole.
Candidate Storage Center
conguration
• The Storage Center must have a server object that matches the server to which the original
volume is mapped.
• The Storage Center must be less than 80% full when including the size of the volume to be
moved.
• The combined original volume IO/sec and Storage Center front end IO/sec must be below a
predened threshold.
Types of Volume Movement Recommendations
There are two types of recommendations: those that are triggered by volume latency threshold denitions, and those that are not. Both
recommend moving one or more volumes to a dierent Storage Center, but volume latency recommendations provide more detail and
include an option to automatically act on the recommendation.
Both types of recommendations can be viewed from the current threshold alerts that contain them. On the Alerts tab of the Threshold
Alerts view, current threshold alerts that contain recommendations display Yes in the Recommend column.
To view the recommendation contained by a current threshold alert, right-click the alert and select Recommend Storage Center to open
the Recommend Storage Center dialog box.
