Metro node redundancy provides reduced 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. .
