4.6 Quality of Service (QoS)
The hyper-converged solution includes application and storage traffic distributed across the entire leaf-spine
network architecture. To improve critical VxFlex OS and storage-related traffic, QoS features on the leaf and
spine switches can be utilized. This section describes some basic QoS configurations and settings to enable
traffic policing through the use of Differentiated Services Code Point (DSCP) marking and priority queuing.
4.6.1 DSCP marking on virtual distributed switches
Differentiated services provide a means to classify traffic using DSCP values. The DSCP values give storage-
related traffic a higher priority than application traffic.
The deployment example uses separate physical NICs, virtual distributed switches and distributed port groups
for storage and application traffic. This configuration allows the use of the traffic filtering and marking feature
on distributed port groups to easily mark different DSCP values on storage and application traffic.
To mark traffic at the VM, use the settings shown below:
1. In vCenter, navigate to Home > Networking.
2. On the VDS, select the ScaleIO-data01 distributed port group.
3. Right-click on the ScaleIO-data01 port group name in the left-hand column and select Edit Settings.
4. Select Traffic filtering and marking.
a. Change the Status to Enabled.
b. Click to add a traffic rule.
c. Enter a descriptive name into the Name field.
d. Keep the default Action as Tag.
e. Check the DSCP value checkbox, and enter 46 as the value.
f. Keep the Traffic direction as Ingress/Egress.
g. Click and add a New IP Qualifier.
h. Change the Protocol to any.
