If all nodes at one site fail in a stretch cluster configuration of Storage Replica, what occurs?

In a stretch cluster configuration using Storage Replica, if all nodes at one site fail, a crucial functionality comes into play: the remaining site can take over the role of the source for replication. This ensures that data continuity is maintained and operations can continue across the remaining operational site.

When the nodes at one site go down, the other site can still access the data that has been replicated there. This becomes critical for maintaining business continuity and ensures that applications and services can continue to function without significant downtime. The nodes from the surviving site will act as the source of replication moving forward, allowing for data synchronization with the failed site once it is restored.

This behavior is a fundamental aspect of how stretch clusters are designed, providing resilience and availability in the event of site failures. It is the mechanism that allows organizations to protect against data loss while managing failover effectively.
