Why each option
A Fabric MetroCluster solution provides both local and site-level failover recovery with support for SMB 3.0, ensuring business continuity across distinct sites.
A 2-node switchless cluster provides local high availability and failover within a single site but does not offer site-level disaster recovery capabilities between distinct locations.
A Fabric MetroCluster solution provides synchronous replication between two geographically separate sites, enabling site-level disaster recovery with automatic failover. Additionally, within each site, the underlying ONTAP cluster provides local high availability and failover, supporting SMB 3.0 continuous availability features for uninterrupted access during component failures or site-wide disasters.
While a 'Stretch MetroCluster' might refer to a specific variant, 'Fabric MetroCluster' is the standard and more encompassing term for the solution that meets both site-level and local failover requirements across two sites using dedicated fabrics.
An 8-node cluster provides high scalability and local failover within a single data center but does not inherently offer site-level disaster recovery between two distinct geographical locations without additional MetroCluster configuration.
