You can deploy and configure additional nodes so that VMware Aria Operations can support larger environments. Figure 1. Workflow - Resize your cluster What to read next Adding High Availability to VMware Aria OperationsYou can dedicate one VMware Aria Operations cluster node to serve as a replica node for the VMware Aria Operations primary node. Adding Continuous AvailabilityContinuous availability prevents data loss in the event of one or more node failures. This mode requires one witness node, one primary node, and one data node divided across two fault domains. The witness node lies outside the fault domains. By default, the primary node is assigned to Fault Domain 1. The data node becomes the replica node and is assigned to Fault Domain 2. The primary node and the replica node create a pair. The number of data nodes including the primary node should always be an even number not exceeding 16. Each data node added to Fault Domain 1 must have a pair in Fault Domain 2 to preserve and replicate data that is added to its peer. VMware Aria Operations Cluster and Node MaintenanceYou perform cluster and node maintenance procedures to help your VMware Aria Operations perform more efficiently cluster and node maintenance involves activities such as changing the online or offline state of the cluster, fault domains, or individual nodes, activating or deactivating high availability (HA) or continuous availability (CA), reviewing statistics related to the installed adapters, and rebalancing the workload for a better performance.
