SmartQoS is implemented based on the partitioned performance in OneFS. Concepts such as dataset, workload, and so on are still applied to SmartQoS. Use the following steps to configure an ops limitation using SmartQoS:
The SmartQoS feature is by default enabled. Use the following CLI command to view the current settings:
# isi performance settings view
Top N Collections: 1024
Time In Queue Threshold (ms): 10.0
Target read latency in microseconds: 12000.0
Target write latency in microseconds: 12000.0
Protocol Ops Limit Enabled: Yes
To disable the SmartQoS feature, use the following command:
# isi performance settings modify --protocol-ops-limit-enabled=false
protocol_ops_limit_enabled: True -> False
A dataset is used to categorize workloads by various metrics, including:
In this example, we use protocol and path to create a test dataset.
# isi performance datasets create --name ds1 protocol path
Created new performance dataset 'ds1' with ID number 1.
Note: Resource usage tracking by 'path' metric is only supported by SMB and NFS.
You can use the WebUI for the same purpose:
