How does VPLEX manage I/O requests during a failover?

VPLEX manages I/O requests during a failover by automatically redirecting I/O to the available path. This functionality is crucial for maintaining continuous data access and availability, especially in a dual-site environment. With VPLEX, if one path becomes unavailable due to a failure, the system dynamically reroutes I/O operations to operational paths without requiring manual intervention, ensuring that the applications relying on the storage can continue to function seamlessly. This automatic failover capability is a key aspect of VPLEX's design, enabling high availability and resilience in storage architectures.

This approach minimizes downtime and enhances performance by ensuring that users and applications remain unaffected during a failover scenario. It contrasts sharply with the other options, which either suggest halting processes, issuing alerts, or prioritizing I/O unnecessarily, all of which would not provide the same level of continuity and efficiency.
