Metro node virtualizes the data that is on storage arrays to create dynamic, distributed, and highly available data centers. Metro node enables connectivity to heterogeneous storage arrays with the ability to manage storage that is provisioned from multiple arrays from a single interface in a data center. The system uses a unique clustering architecture that gives servers at multiple data centers read/write access to shared block storage devices. Metro node technology enables transparent movement of data between storage arrays for the connected hosts without disruption to operations and protects the data from failures of single components and disasters. For more information, see the Dell EMC Storage Systems Product Guide for the metro node appliance.
