What is the primary disadvantage of a stand-alone configuration in Storage Replica?

In a stand-alone configuration using Storage Replica, the primary disadvantage is the absence of an automatic failover process. This means that if one of the systems in the configuration goes down or fails, there is no automatic mechanism to switch operations to a secondary system. This can significantly impact availability, as administrators must manually manage failover to ensure continuity of service.

In contrast, a configuration that includes high availability typically has built-in features that facilitate automatic failover, thus reducing downtime and ensuring that services remain uninterrupted. The manual intervention required in a stand-alone configuration can lead to prolonged outages if issues arise, making it less desirable for critical applications that require reliable uptime.

The inability to automatically switch over creates operational challenges, particularly in environments that demand high availability and quick recovery from failures.
