SSSE Architecture

The SSSE architecture is illustrated in Figure 4.

Each SSSE user's computer interacts with the Siebel database and the Microsoft Exchange Server host. The communications that occur between the Siebel database and the PIMSI Engine and PIMSI Dispatcher servers are separate from the communications that occur between the Siebel database and individual SSSE user computers. The Exchange Connector acts as an intermediary for communications between PIMSI Engine and the Microsoft Exchange Server host.

Figure 4. SSSE Architecture

If you are using a DCOM Exchange Connector with Microsoft Exchange Server 2007, you can deploy it on a host computer at a central location within the Siebel Enterprise, or you can deploy multiple DCOM Exchange Connectors on hosts at geographic locations near Microsoft Exchange Servers.

If your implementation includes firewalls between SSSE components, you might have to open specific ports in the firewall to allow the various parts of the implementation to communicate with each other. For more information about using SSSE with firewalls, see Configuring Firewalls for Use with SSSE.
