An organization’s datastores are configured in a fully automated Storage Distributed Resourc
Scheduler (SDRS) cluster. The vSphere administrator determines that virtual machines are being
migrated between datastores even though the datastores look evenly balanced. On further
investigation, the administrator determines that the datastore’s utilization percentages differ by 2%.
Which Storage DRS setting should the administrator change to prevent the virtual machines from
migrating prematurely?
A.
Edit the Storage DRS cluster settings to increase the percentage of the Space Utilization
Difference threshold
B.
Edit the Storage DRS cluster settings to increase the percentage of the I/O imbalance threshold
C.
Edit the Storage DRS cluster settings to increase the size of the Space Utilization Difference
threshold
D.
Edit the Storage DRS cluster settings to increase the size of the I/O imbalance threshold

Step 3. Generate Migration Recommendation Candidates
The Minimum Space Utilization Difference setting is accessible in the advanced option section of the datastore
cluster. This setting defines the difference in utilization percentage that a destination datastore must be from the
source datastore. The default setting is 5 percent. vSphere Storage DRS regards a datastore as a valid
destination for load-balancing migrations when the space utilization differs by more than 5 percent from the
source datastore. This setting can have a value of between 1 and 50 percent.
