Since lab resources are often reassigned or reused for new functions, they are built according to a template. This allows repurposing without always requiring a lab change request. The following figure shows the two general pattern for server deployments.
The server is configured with all networks, even if not currently needed. Server host are named sequentially when provisioned. Likewise, the ports for the 3 data networks are aligned with their correlative port assignments. IP assignment is also correlated, 10 is added to the number in the host server name to identify the last IP value. For the illustrative example the OSC-INF-01 server has an OAM IP of 10.0.1.11, the Control IP of 10.0.2.11, and a User IP of 10.0.3.11.

The O-Cloud is intended, when complete to support 3 different clusters patterns. The Simplex, Duplex, and Duplex patterns are defined more deeply on the project wiki: https://wiki.o-ran-sc.org/display/IN/INF+Project+Hardware+Requirements. The generalized pattern is shown in the figure below.
The figure also depicts the Integration (INT) Project Server. This server host the INT Open Test Framework (OTF) in which all projects can use to create automated test for unit/feature testing, pairwise testing, end-to-end test/demonstrations. It can also execute a suite of tests such as Release and Certification tests.
