CDP Private Cloud Base is deployed on a cluster of multiple physical server nodes. Each node has a particular configuration that is designed for its role in the cluster. These nodes are further specialized through the software services assigned to them. There are two basic types of nodes: Infrastructure nodes and Worker nodes. Infrastructure nodes run on a common server configuration based on PowerEdge servers. Infrastructure nodes include four specific node types: Master node, Utility node, Worker nodes, and Gateway node.
Note: Dell Technologies recommends using a ratio of five worker nodes to one PowerScale cluster as a starting point.
Although these nodes use the same physical configuration, they take on different roles based on the software services deployed on each of them. Role assignments may also differ depending on the cluster size and the services that are used. See Runtime Cluster Hosts and Role Assignments in the CDP Private Cloud Base documentation for more details.
