You have to consider important requirements while creating nodes in a VMware Aria Operations. What to read next Using IPv6 with VMware Aria OperationsVMware Aria Operations supports both, Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). All nodes in the cluster must follow the same protocol. For endpoint communications, you can use IPv4 or IPv6. If the environment only supports the IPv6 protocol, the Prefer IPv6 flag must be activated during the OVF deployment for each node. If you set the Prefer IPv6 flag, then VMware Aria Operations uses IPv6 for all communications. Cluster RequirementsWhen you create the cluster nodes that make up VMware Aria Operations, you have general requirements that you must meet. Sizing and Scaling Requirements The CPU, memory, and disk requirements that meet the needs of a particular environment depend on the number and type of objects in your environment and the data collected. This includes the number and type of adapters installed, the use of HA (High Availability) or CA (Continuous Availability), the duration of data retention, and the quantity of specific data points of interest.
