SANs Across MANs and WANs Dr. Joseph White, Distinguished Engineer, Juniper Networks Extending storage networks across distance is essential to BC/DR (Business Continuance/Disaster Recovery), compliance, and data center consolidation. This tutorial will provide both an overview of available techniques and technologies for extending storage networks into the Metro and Wide area networks and a discussion of the applications and scenarios where distance is important. Transport technologies and techniques discussed will include SONET, CWDM, DWDM, Metro Ethernet, TCP/IP, FC credit expansion, data compression, and FCP protocol optimizations (Fast Write, etc). Scenarios discussed will include disk mirroring (both synchronous and asynchronous), remote backup, and remote block access. Learning Objectives
