Managing QoS Proles
QoS proles describe QoS settings that can be applied to volumes.
By dening QoS proles to apply to volumes, you potentially limit I/Os that the volumes can perform, and also dene their relative priority
during times of congestion.
You can also dene a group QoS prole that can be applied to multiple volumes to limit the I/Os that the volumes can do in aggregate.
Create a QoS Prole
QoS proles 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 proles for a Storage Center, the Allow QoS Prole Selection option must be selected on the Storage
Center Preferences settings.
• To enable QoS proles to be enforced, the QoS Limits Enabled and Server Load Equalizer Enabled options must be selected on the
Storage Center Storage settings.
Steps
1 If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2 In the Storage tab navigation tab, right-click QoS Proles and select Create QoS Prole.
The Create QoS Proles. dialog box opens.
3 Congure the QoS prole.
a In the Name eld, type a name for the QoS prole.
b Select a prole type: either Volume QoS Prole or Group QoS Prole.
c (Optional for volume QoS proles only) In the Relative Priority eld, type a number to identify the priority compared to other
QoS proles.
d (Optional for volume QoS proles only) Select Enable Latency Threshold Alert, then type a value in milleseconds for the latency
alert threshold.
e (Optional) Select Limit by IOPS, then type a value for the maximum I/O per second allowed.
f (Optional) Select Limit by Bandwidth, then type a value for the maximum MB per second allowed.
4 Click OK.
Edit a QoS Prole
Modify the QoS prole to change the attributes that control the QoS for any volume or group to which it is applied.
1 If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2 In the Storage tab navigation tab, right-click QoS Proles and select Edit Settings.
The Edit QoS Prole dialog box opens.
3 Where allowed, modify the values. The prole type eld cannot be modied.
4 Click OK.
