SnapMirror Business Continuity (SMBC) is a NetApp solution that meets the needs of a storage solution with a zero RPO and near-zero RTO for all NAS workloads. SMBC is a business continuity solution that enables transparent application failover and failback between two ONTAP clusters in a LAN or MAN environment1. SMBC provides application-level granularity and automatic failover based on the ONTAP Mediator service1. SMBC leverages the existing SnapMirror Synchronous (SM-S) technology to replicate data synchronously between the clusters and maintain zero RPO12. SMBC also supports both NFS and SMB protocols for NAS workloads13.
