Required inputs
Storage and switch endpoints, protocol, redundant paths, latency target, distance and maintenance window.
Solution
Storage Fabric Connectivity
Storage and backup network optics where latency, compatibility and support lifecycle matter.
Review This TopologyDesign constraint
Endpoint qualification, deterministic failover, cable serviceability and matching spares on both fabrics.
Acceptance output
Dual-fabric failover, sustained traffic, error counters, firmware record and paired spare plan.
Storage Fabric Connectivity
Keep storage-path latency, redundancy and support lifecycle separate from ordinary server uplinks when choosing optics or cables.

Plan and validate the route
Endpoint qualification, deterministic failover, cable serviceability and matching spares on both fabrics.
Record endpoints
Storage and switch endpoints, protocol, redundant paths, latency target, distance and maintenance window.
Test the constraint
Endpoint qualification, deterministic failover, cable serviceability and matching spares on both fabrics.
Prevent the likely failure
A link that trains can still be unsuitable when failover, error recovery or the second fabric was not tested under load.
Define acceptance
Dual-fabric failover, sustained traffic, error counters, firmware record and paired spare plan.
