Note:
An external Oracle database may be installed in place of the
standard database, resulting in an E-Y-N configuration. The external
database (E) on X computers and the load balancer (LB) on Y other
computers are in a Microsoft Cluster Server for failover. The server
is on one or more additional computers.

Using multiple systems for high availability
When configuring multiple Lexmark Intelligent Capture systems, you can connect them to a hardware load balancer or
Global Site Selector (GSS) to provide high availability, without using clustering, as well as increased capacity.

Each system group contains two identical Lexmark Intelligent Capture systems. Jobs are balanced between these
systems in each group by the hardware load balancer or GSS. If a failure occurs in one system in a group, then the other
system in the group receives all incoming jobs until the failed system can be restored.
