Do HyperMetro LUNs support value-added features such as snapshots and remote replication?


A LUN that has been added in the HyperMetro domain support snapshots and can function as the primary LUN in remote replication, that is, the active-active data center solution can be expanded to the 3DC disaster recovery solution. In addition, active-active LUNs are compatible with value-added features such as SmartQoS, SmartCache, and SmartTier.

Introduction to the Dorado HyperMetro feature
HyperMetro creates active-active relationships between two data centers so that both the data centers are running and carry the same host services concurrently. A mutual backup relationship is set up between the storage arrays in the two data centers. If the storage array in one data center malfunctions, the storage array in the other data center automatically takes over services without data loss or service interruption, improving the data center serviceability and system resource utilization.
