WIDE AREA NETWORK BASICS
This tutorial covers the basics of WANs, which are used to connect two or more LANs.

WIDE AREA NETWORK OPTIMIZATION AND ACCELERATION
One of the major issues facing today's corporate data centers is growth. Companies are turning to WAN optimization and WAN acceleration technologies that improve bandwidth utilization by reducing the effective amount of data being transferred and alleviating the inefficiencies inherent in WANs. This chapter covers some common data reduction tactics.

WIDE AREA NETWORK MIRRORING AND REPLICATION
One of the easiest ways to protect vital data is to mirror the data to a second location. This chapter of the WAN expansion guide focuses on remote mirroring and replication.

WIDE AREA NETWORK BACKUP, ARCHIVES AND DISASTER RECOVERY
Backups, archives and DR serve different storage purposes, but all three disciplines have the same basic objective of data protection.

WAN/WAFS AND REMOTE OFFICES
Today, the Internet and dedicated wide area network (WAN) resources allow direct connections between the data center and remote offices. Remote offices can now access applications and data from the data center, and backup tasks can take place without the intervention of any remote employees. This chapter highlights the essential ideas of WAN in the remote office.

ISCSI AND SAN INTERCONNECTIONS
SAN data has traditionally existed as its own "island" of Fibre Channel technology -- accessible only to applications through the data center. But the need to implement business continuity and disaster recovery plans has forced data centers to connect Fibre Channel SANs across the wide area network (WAN).
