4 In the Automation Level column, select an automation level for the virtual machine.
Option Description
Default (Manual)
Placement and migration recommendations are displayed, but do not run
until you manually apply the recommendation.
Fully Automated
Placement and migration recommendations run automatically.
Disabled
vCenter Server does not migrate the virtual machine or provide migration
recommendations for it.
5 In the Keep VMDKs together column, deselect the check box to override default VMDK affinity.
See “Override VMDK Affinity Rules,” on page 377.

Set Up Off-Hours Scheduling for Storage DRS
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.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Enable Storage DRS.
Procedure
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.
