An administrator enables NDB Multi-Cluster on Cluster A.

NDB Multi-Cluster is a feature that allows multiple Nutanix clusters to share a common NDB service for database management and automation. NDB service consists of two components: NDB Server and NDB Agent. NDB Server is the central component that provides the web UI, REST API, and database orchestration logic. NDB Agent is the component that runs on each Nutanix cluster and communicates with the NDB Server to perform database operations.

When NDB Multi-Cluster is enabled on Cluster A, it becomes the primary cluster that hosts the NDB Server VM. Cluster B, which is registered with NDB, becomes a secondary cluster that hosts only the NDB Agent VM. Therefore, Cluster A has both NDB Server and NDB Agent, while Cluster B has only NDB Agent. This configuration allows Cluster B to leverage the NDB service running on Cluster A for database management and automation.
