Managing QoS Profiles
QoS profiles describe QoS settings that can be applied to volumes.
By defining QoS profiles to apply to volumes, you potentially limit I/Os that the volumes can perform, and also define their relative priority
during times of congestion.
You can also define a group QoS profile that can be applied to multiple volumes to limit the I/Os that the volumes can do in aggregate.
Create a QoS Profile
QoS profiles include a set of attributes that control the QoS behavior for any volume to which it is applied.
Prerequisites
• To enable users to set QoS profiles for a Storage Center, the Allow QoS Profile Selection option must be selected on the Storage
Center Preferences settings.
• To enable QoS profiles to be enforced, the QoS Limits Enabled and Server Load Equalizer Enabled options must be selected on
the Storage Center Storage settings.
