This comparison covers the performance, cost, and features of FC and FCoE storage protocols
Updated August 16, 2026
FC
Best when existing infrastructure is already in place, such as in legacy data centers
FCoE
Best when converged network infrastructure is available, such as in modern data centers with high-performance requirements
FCoE offers higher performance and converged network support, making it a better choice for modern data centers. While FC has an established ecosystem, its higher cost and separate network infrastructure requirements make it less attractive. As copper's grip on AI scaling starts to slip, FCoE's ability to support converged networks will become increasingly important.
