IO load-balancing decisions. Load balancing based on capacity or IO is achieved by
performing Storage vMotion migrations between the source and destination data stores
within a data store cluster.
Tip
If you wish to perform data store maintenance for any reason or migrate between
arrays, you can put one of more data stores of a data store cluster into
maintenance mode. This will enforce the evacuation of all virtual disks and files
on the data stores going into maintenance mode into the remaining data stores that
make up the data store cluster. Storage DRS will distribute the load and make
sure that your load balancing policies is adhered to.
The example shown in
Figure 6.33
is of the standard storage DRS options, including the
Storage DRS Automation Level, configured for Fully Automated, and the I/O metrics
settings, which are disabled. You may wish to set Storage DRS to No Automation
(Manual Mode) for a period of time during operational verification testing or if you are
unfamiliar with Storage DRS and data store clusters, until you are familiar and
comfortable with the recommendations it makes.
