3. Domain infrastructure

This chapter covers the infrastructure foundation of a Nubus for UCS domain. A Nubus for UCS domain relies on multiple systems with different roles and responsibilities that work together to provide directory, authentication, and management services.

The Primary Directory Node serves as the central hub of your domain, storing and managing all domain data. To keep your domain available and resilient, you need to understand both the system roles you can deploy and the strategies for protecting against single points of disruption.

System roles

Understand the system roles you can deploy in a Nubus for UCS domain, from the Primary Directory Node that stores all domain data to Backup, Replica, and Managed Nodes. See Understanding system roles.

Redundancy and failover for the Primary Directory Node

Protect your domain against disruption to the Primary Directory Node by distributing directory data across Backup and Replica Directory Nodes and by promoting a Backup Directory Node to Primary when needed. See Redundancy and failover for the Primary Directory Node.
