What are the dual fabrics used for in BE connectivity?

In the context of BE (Backend) connectivity within VPLEX systems, the use of dual fabrics is primarily focused on providing fault tolerance. This means that if one fabric experiences a failure, the other fabric continues to operate, ensuring that data access and connectivity remain uninterrupted. This redundancy is critical for high availability and reliability in storage environments, as it mitigates the risk of a single point of failure.

By maintaining dual fabrics, VPLEX can swiftly reroute traffic through the remaining operational fabric without affecting the overall system performance or data integrity. This architecture allows organizations to achieve continuous operation despite potential hardware or network issues, which is essential for mission-critical applications and data availability strategies.

While maximizing bandwidth and reducing latency are certainly important considerations in network design, they are not the main reason for implementing dual fabrics in this specific context. Enhancing encryption is also not a function of the fabric design but rather pertains to data security measures that can be applied independently.
