Viewing Traffic Control Policies

Context

There are two types of traffic control policies:

• Upper-limit traffic control policy: controls the upper limits of bandwidth and IOPS.
• Lower-limit traffic control policy: controls the lower limits of bandwidth and IOPS and the upper limit of latency.

You can only select LUNs, snapshots, or file systems with high I/O priority for a lower-limit traffic control policy, and you must not change the priorities of the LUNs, snapshots, or file systems that are working with a lower-limit traffic control policy.

Procedure

1. Log in to DeviceManager.
2. Choose Provisioning > Resource Performance Tuning > SmartQoS > Traffic Control.
3. View the traffic control policy information.
   Table 3-4 describes the related parameters.
