20 SFVRA Connection Manager
SFVRA Connection Manager is designed to provide a “fault tolerant” environment. Network
administrators can implement multiple instances of SFVRA-CONN running on multiple machines.
These instances can communicate with each other to provide dynamic resource assignment, such
as load balancing. The databases themselves can be duplicated in real-time using the replication
services of the leading SQL database engines.
You may want to have regional centers for Remote Access Switches that are connected via
dedicated or switched circuits. Define these connections locally on the Remote Access Switches,
while all other users are authenticated remotely using SFVRA-CONN.
