You can create a scheduled task to change Storage DRS settings for a datastore cluster so that migrations for fully automated datastore clusters are more likely to occur during off-peak hours.

You can create a scheduled task to change the automation level and aggressiveness level for a datastore cluster. For example, you might configure Storage DRS to run less aggressively during peak hours, when performance is a priority, to minimize the occurrence of storage migrations. During non-peak hours, Storage DRS can run in a more aggressive mode and be invoked more frequently.

Launch the vSphere Client and log in to a vCenter Server system.

Enable Storage DRS.

1

In the vSphere Client inventory, right-click a datastore cluster and select Edit Settings.

2

In the Edit Datastore Cluster dialog box, click SDRS Scheduling.

3

Click Add.

4

Type the time and select the days for the task to run.

5

Click Next.

6

Specify the start settings for the task.

a

Type a description for the start settings.

For example, Change SDRS Configuration.

b

Select an automation level.

c

To disable I/O metrics for Storage DRS recommendations, select the check box.

When you disable I/O metrics for Storage DRS recommendations, I/O metrics are not considered as part of Storage DRS recommendations or automated migrations for the datastore cluster.

d

Set the Utilized Space threshold.

Use the Utilized Space slider to indicate the maximum percentage of consumed space allowed before Storage DRS is triggered. Storage DRS makes recommendations and performs migrations when space use on the datastores is higher than the threshold.

e

Set the I/O latency threshold.

Use the I/O Latency slider to indicate the maximum I/O latency allowed before Storage DRS is triggered. Storage DRS makes recommendations and performs migrations when latency is higher than the threshold.

Note

The Storage DRS I/O Latency threshold for the datastore cluster should be lower than or equal to the Storage I/O Control congestion threshold.

f

Set the I/O imbalance threshold.

Use the I/O Imbalance Threshold slider to indicate the aggressiveness of I/O load balancing. Storage DRS makes recommendations and performs migrations if the I/O load imbalance level exceeds the threshold.

7

Click Next.

8

Specify the end settings for the task.

To restore the Storage DRS settings to the pre-task configuration, select the Restore settings check box.

To specify settings other than the pre-task configuration, deselect the Restore settings check box.

9

Review the Ready to Complete page and click Finish.

The scheduled task runs at the specified time.
