help NetApp MetroCluster FAQ

What problem does NetApp MetroCluster solve?

MetroCluster is designed for high availability and disaster recovery across two sites. In ONTAP environments, it can keep mirrored storage available if one site fails.

Does NetApp MetroCluster use synchronous replication?

Yes, classic MetroCluster uses synchronous mirroring so committed writes are protected across sites. NetApp also has related ONTAP replication technologies such as SnapMirror for other disaster recovery patterns.

What is the difference between MetroCluster FC and MetroCluster IP?

MetroCluster FC uses Fibre Channel infrastructure between sites, while MetroCluster IP uses IP-based networking for the intersite links. MetroCluster IP became a major direction for newer ONTAP deployments because it reduces dependence on dedicated FC extension gear.

Is MetroCluster only for backups?

No. It is an availability architecture, not just a backup product. Backups still matter because MetroCluster protects service continuity, while snapshots, SnapMirror, or external backup tools protect against deletion, corruption, and ransomware scenarios.
