VMware supports Storage DRS and Storage IO Control on EMC VPLEX in each of the two configurations with the restrictions described below.

VPLEX Local:
In a VPLEX Local configuration VPLEX volumes are contained within site/location. In this configuration the following restrictions apply:

• Storage IO Control is supported
• Storage DRS is supported
• A Datastore Cluster should only be formed out of similar volumes
• It is recommended to run Storage DRS in Manual Mode to control the point in time migrations occur

VPLEX Metro:
In a VPLEX Metro configuration VPLEX volumes are distributed across locations/sites. In this configuration the following restrictions apply:

• Storage IO Control is not supported
• Storage DRS is only supported when IO Metric is disabled
• It is recommended to run Storage DRS in Manual Mode to control the point in time migrations occur
• Each location/site should have a Datastore Cluster formed only out of dvols (Distributed VPLEX volumes) which are part of the same consistency groups, and only with site bias to that particular location / site.
• Example: Site A will have Datastore Cluster A which contains all dvols with bias to Site A.
