Why Dynamic FCoE using FabricPath

Why FCoE?

Elimination of separate network infrastructures for SAN and LAN traffic.

Reduction in hardware requirements, such as cabling and server adapters, and lowering cost

Increasing deployment agility for multi-protocol networks thus preserving long-term investments

End-to-end single converged Unified Fabric

Why Dynamic FCoE using FabricPath

Why FabricPath?

Reduction / elimination of Spanning Tree Protocol (STP)

Better stability and convergence Characteristics

Simplified configuration

More efficiently load-balance multi-protocol traffic within the data center

Improves high availability percentages as scale increases

“VLAN anywhere” – flexibility, L2 adjacency, and VM mobility
