In this chapter, we go over the end-to-end deployment of a high availability (HA) IBM Lotus Notes Traveler server.
There are two main influencing factors to choose a stand-alone server versus an HA Lotus Notes Traveler implementation. These include:
- The number of devices that the Lotus Notes Traveler is to service.
- The requirement about the up-time or availability if the a server instance becomes unavailable.
In our scenario, we have a medium sized company that implements the Lotus Notes Traveler solution. This company must service about 2,000 devices and must have their sales staff able to access their email from the road 24x7.
Given the number of devices, a stand-alone server can provide the services required. However, 2,000 devices is the limit for a stand-alone server and leaves no room for growth. The need for the sales team to have reliable constant access to their email requires the solution to be implemented in a high availability environment. To provide 24x7 availability, we must provide backup servers to service the client devices if one of the servers, including the Lotus Notes Traveler server, becomes unavailable for some reason (server patch, upgrade, crash, operating system issue, and so on).
Installation, configuration, and user deployment are three major milestones in deploying an IBM Lotus Notes Traveler environment. We cover the installation and configuration in this chapter. User deployment to devices is covered in full detail in 5.0 User deployment
