Which of the following can provide the capability of mirroring a LUN between two storage arrays?

SAN virtualization consolidates and abstracts physical storage resources from different arrays into a single logical pool, allowing for advanced data services such as LUN mirroring, migration, and replication independent of the underlying hardware vendor. This abstraction layer manages the data movement and synchronization between the two storage arrays.

De-duplication is a data reduction technique that eliminates redundant copies of data, storing only unique instances, and does not provide LUN mirroring functionality.

Thin provisioning is a storage allocation method where physical storage is allocated only as data is written, rather than reserving all space upfront, and it does not facilitate LUN mirroring.

A Virtual SAN (VSAN) typically refers to a software-defined storage solution that pools direct-attached storage from multiple hosts to create a shared datastore, often within a hyperconverged infrastructure, which is different from mirroring LUNs between two distinct hardware storage arrays.
