LUN Masking

The LUN masking mechanism is used to configure required security policies to present the storage LUNs to only those systems and cloud storage devices that require access via the interfaces and configuration options provided by physical storage vendors.


Two storage administrators are discussing which SAN configurations will offer the MOST
confidentiality. Which of the following configurations would the administrators use? (Select TWO).

A. Deduplication
B. Zoning
C.Snapshots

D.Multipathing

E.LUN masking



LUN masking can control which LUNs are visible to each vSphere host. This is the opposite of zoning, where the storage array configuration determines which LUNs are visible to a host. This feature allows multiple vSphere hosts to be connected to a storage with multiple LUNs, while allowing only one vSphere host, which you specify, to see some particular LUNs. This feature is the same as EMC CLARiiON or VNX provide LUN masking in the storage group at the array level. You can add the host and LUNs to a storage group, and then the host will only be able to see those LUNs.
