Metro node features allow the highest possible resiliency in the event of an outage. The following figure shows a metro node Metro configuration where storage has become unavailable at one of the cluster sites.

Metro node redundancy provides zero Recovery Time Objective (RTO) and Recovery Point Objective (RPO) because, metro node AccessAnywhere mirrors all data, applications continue without disruption using the back-end storage at the unaffected site.

With the Federated AccessAnywhere feature of metro node, the data remains consistent, online, and always available. Metro node does not need to ship the entire file back and forth like other solutions. It only sends the changed updates as they are made, greatly reducing bandwidth costs and offering significant savings over other solutions.

To know more about high availability with metro node, see Chapter 4 Integrity and resiliency. .
