22 Enterprise Server Installation and Migration Guide

High Availability Considerations

This architecture depicts a highly available architecture supporting up to 60,000 endpoints. There are two Dell Enterprise

Servers set up in an active/passive configuration. To failover to the second Dell Enterprise Server, stop the services on the

primary node and point the DNS Alias (CNAME) to the second node. Start the services on the second node and launch the

console to ensure the application is working properly. Services on the second (passive) node should be configured as “Manual”

in order to prevent those services from accidentally starting during regular maintenance and patching.

An organization can also choose to have an

SQL Cluster database server. In this configuration, the Dell Enterprise Server should

be configured to use the cluster IP or hostname.

NOTE: Database replication is not supported.

Client traffic is distributed across three internal front-end server

s. Optionally, multiple front-end servers can also be placed in the

DMZ for activating endpoints and/or publishing policies to endpoints over the Internet.
