White Paper Abstract:
Proliferation of storage traffic due to disaster recovery and business continuance requirements, combined with the high cost associated with downtime or loss of data, justifies the need for interconnecting geographically dispersed data centers. At the same time, mission-critical applications such as e-business and customer relationship management, and emerging applications such as streaming media, are impacting all parts of the transport infrastructure - access, metropolitan-area network (MAN), and WAN. This document describes an innovative solution to efficiently transport Gigabit Ethernet and storage area network (SAN) protocols from multiple dense wavelength-division (DWDM) access rings across the core SONET/SDH network. It explains how the Cisco® ONS 15454 2.5-Gbps Data Muxponder Card can aggregate SAN services - Fibre Channel, Fiber Connectivity (FICON), Enterprise Systems Connection (ESCON), and Gigabit Ethernet - into the DWDM access ring for transport over the core SONET/SDH infrastructure.
