Scenario A: 5 Nodes

This five nodes scenario (depicted in Fig. 2) involves the presence of a single tenant.

Before starting the installation, bear in mind to:

• Always start with the installation of Mesh and Directory Roles

• When installing multiple Roles on a Node, the tasks listed in Bootstrap Carbonio* and Join Carbonio Mesh steps can be made only once, after all packages of the Roles have been installed

Note

You can skip the installation of Nodes 4 and 5 if you do not need Docs Editor, Files, Chats, and Video Calls.
