You have to consider important requirements while creating nodes in a vRealize Operations Manager. Using IPv6 with vRealize Operations ManagervRealize Operations Manager supports both, Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). You can use IPv4 or IPv6 or both. If the environment has a dual-stack support with both IPv4 and IPv6 protocols, all nodes in the cluster must follow the same protocol. When using IPv6, the Prefer IPv6 flag must be enabled during the OVF deployment for each node. If you set the Prefer IPv6 flag, vRealize Operations Manager uses IPv6 for it internal communications. It does not affect how vRealize Operations Manager handles its external communications. The use of IPv6 with vRealize Operations Manager requires that certain limitations be observed. Cluster RequirementsWhen you create the cluster nodes that make up vRealize Operations Manager, 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.
