You can add, remove, and upgrade the nodes of a vRealize Log Insight cluster.

Note:

WAN clustering is not supported by vRealize Log Insight. Current versions of vRealize Log Insight do not support WAN clustering (also called geoclustering, high-availability clustering or remote clustering). All nodes in the cluster should be deployed in the same Layer 2 LAN. In addition, the ports described in Ports and External Interfaces must be opened between nodes for proper communication.
