•Increased IT efficiency and business agility
A converged network streamlines and eliminates repeated administrative tasks such as server and network provisioning with a “wire once” deployment model. The converged network also improves business agility letting data centers dynamically and rapidly respond to requests for new or expanded services, new servers and new configurations. The converged network fully complements server virtualization in addressing the
•Seamless extension of Fibre Channel SANs in the data center
Fibre Channel is the predominant storage protocol deployed by enterprise data centers. With the adoption of blade servers and server virtualization, there is an increased demand for Fibre Channel SANs in these environments. FCoE addresses this requirement by leveraging 10Gb/s Ethernet and extending proven Fibre Channel SAN benefits. The use of
•Alignment with existing operating models and administrative domains
FCoE based converged networks gives IT architects the ability to design a data center architecture that aligns with existing organization structure and operating models. This minimizes the need to unify or significantly overhaul operating procedures used by storage and networking IT staff.
FCoE Technology Overview
FCoE is the industry standard that drives network convergence in the enterprise data center. The FCoE technology leverages lossless Ethernet infrastructure to carry native Fibre Channel traffic over Ethernet.

Leveraging 10Gb/s Ethernet to carry both the data networking and storage networking traffic enables convergence in the data center networks and thus reduces the number of cables, switch ports and adapters, which lowers the overall power and cooling requirements and the total cost of ownership.
