Which two reasons would prevent Storage Distributed Resource Scheduler (SDRS) from operating on a datastore? (Choose two.)
A. The datastore has Storage I/O Control disabled.
B. The datastore is connected to an unsupported host.
C. The datastore is hosted on an NFS server.
D. The datastore is hosted on an iSCSI server.
Correct Answer: AB
Explanation/Reference:
Explanation: Storage DRS to datastores is like DRS to hosts. It moves VMDKs from heavily utilized to less utilized datastores according to preset space and I/O metrics, making efficient storage management more achievable.
Storage DRS can run in automatic mode, but most admins are using it in manual mode. This is understandable as we must keep in mind that Storage vMotion is not as light as vMotion, and hence should not be taken lightly.
Storage DRS does use other storage management technologies like Storage I/O Control (SIOC), and can benefit from others like Profile-Driven Storage and vSphere API for Storage Awareness (VASA).
