Deploying manager nodes

Manager nodes provide optimized stability and performance for Explore clusters and are required for clusters with six or more nodes. A manager node is dedicated to cluster management tasks and does not store records. This guide provides guidelines for adding three manager nodes to new and existing clusters with six or more data nodes.

Manager nodes are virtual appliances with reduced resource specifications. Explore clusters typically require that all nodes match in both appliance type (virtual or physical) and size (resource specifications). However, manager nodes are the exception: a virtual manager node can be added to a cluster that has physical nodes and different resource specifications. Your data-only nodes should still match.
