Metro node is a true active/active synchronous replication solution that allows customers to gain an RTO and RPO of zero, which means no downtime and no data loss in case of an adverse data center event.
Metro node provides a Recovery Point Objective (RPO) equal to zero, meaning there will be zero data loss. Metro node also provides a zero Recovery Time Objective (RTO), which means the time to recover is zero time or immediately. • Automatic Site Failover – The witness virtual machine helps mitigate a site failure.
