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.
The following scenarios can cause vCenter Server to disable Storage DRS for a datastore.
The datastore is shared across multiple data centers.
Storage DRS is not supported on datastores that are shared across multiple data centers. This configuration can occur when a host in one data center mounts a datastore in another data center, or when a host using the datastore is moved to a different data center. When a datastore is shared across multiple data centers, Storage DRS I/O load balancing is disabled for the entire datastore cluster. However, Storage DRS space balancing remains active for all datastores in the datastore cluster that are not shared across data centers.
The datastore is connected to an unsupported host.
Storage DRS is not supported on ESX/ESXi 4.1 and earlier hosts.
The datastore is connected to a host that is not running Storage I/O Control.
