DRS Evaluation Schedule
Normally, Storage DRS runs an evaluation every 8 hours (this can be adjusted; refer back to the
section “Modifying the Storage DRS Runtime Behavior”). Storage DRS will include the new
anti-afi nity rule in the next evaluation. If you want to invoke SDRS immediately, the Storage
DRS tab of the datastore cluster, shown in Figure 12.41, offers the option to invoke SDRS imme-
diately using the Run Storage DRS link.

Use the Run Storage
DRS link to invoke
SDRS on demand.
As you can see, SDRS has a tremendous amount of l exibility built into it to allow vSphere
administrators to harness the power of SDRS by tailoring its behavior to best suit their specii c
environments.
In the next chapter, we'll move into a review and discussion of monitoring and alarms and
show what tools or features VMware vSphere offers administrators in the realm of performance
monitoring.
