When two metro node clusters are connected together with metro node Metro, metro node gives you shared data access between sites. Metro node can withstand a component failure, a site failure, or loss of communication between sites and still keep the application and data online and available.
Metro node Metro ensures that if a data center goes down, or even if the link to that data center goes down, the other site can continue processing the host I/O.
In the following figure, despite a site failure at Data Center B, I/O continues without disruption in Data Center A.
