QUESTION 3:
An administrator is working to implement Storage Profiles in their environment.
Which two ways can storage capabilities be generated? (Choose two.)
A. They are generated by Datastore Clusters as LUNs are added to the cluster.
B. They are automatically determined by the Storage Profile when it is created.
C. They can be retrieved from the array through the VMware APIs for Storage Awareness (VASA).
D. They can be manually generated by the administrator.
Answer: C,D
Explanation:
Understanding Storage Capabilities
A storage capability outlines the quality of service that a storage system can deliver. It is a
guarantee that the storage system can provide a specific set of characteristics for capacity,
performance, availability, redundancy, and so on.
If a storage system uses Storage APIs – Storage Awareness, it informs vCenter Server that it can
guarantee a specific set of storage features by presenting them as a storage capability. vCenter
Server recognizes the capability and adds it to the list of storage capabilities in the Manage
Storage Capabilities dialog box. Such storage capabilities are system-defined. vCenter Server
assigns the system-defined storage capability to each datastore that you create from that storage
system.
NOTE:
Because multiple system capabilities for a datastore are not supported, a datastore that spans
several extents assumes the system capability of only one of its extents.
You can create user-defined storage capabilities and associate them with datastores. You should
associate the same user-defined capability with datastores that guarantee the same level of
storage capabilities. You can associate a user-defined capability with a datastore that already has
a system-defined capability. A datastore can have only one system-defined and only one userdefined
capability at a time.
