FULLY-SYNCHRONIZED DATABASES FOR GEOGRAPHICAL DISASTERS
The Disaster Recovery FT Solution incorporates two separate network connections to each fault tolerant server: one to the corporate network and one to a wide area network (WAN). The dedicated WAN connection enables synchronization of databases, so each server is able to support local applications, as well as host applications running on the remote server.

In the event of a major disaster at Site A, the corporate network redirects users to Site B, where they can quickly log back into their accounts with fully-updated data. (see diagram above)
