Evolving SAN, GbE/10GbE, and Metro Ethernet Technologies ◾ 231
◾ Deploy GbE or 10GbE in the campus (backbone).
◾ Deploy GbE or 10GbE in the data center to connect servers or blade server clusters.
◾ Use FC/SAN technology for connecting virtualized or nonvirtualized storage devices in the
data center. Plan the use of 10 Gbps FC.
◾ Use IP-tunneled SANs for data-center-level connectivity beyond the local data center (e.g.,
for disaster recovery/data replication applications).
◾ Deploy power over Ethernet at the enterprise level.
◾ Deploy LAN QoS (IEEE 802.1p/1Q).
◾ Use VLANs for administrative purposes, but do so sparingly.
◾ Use the Rapid Spanning Tree Algorithm for faster convergence (both at the local and metro
levels).
◾ Use state-of-t ...
