Node architecture depicts the nodes and services in a CDP Private Cloud Base deployment.
The cluster infrastructure consists of multiple physical server nodes. Each node has a physical configuration that is specialized for its role in the cluster. These nodes are further specialized through the software services that are assigned to them. The table below defines the various cluster nodes and their physical configuration.
|Master node||This node runs all the services that are required to manage the cluster storage and compute services.||Infrastructure node|
|Utility node||This node runs Cloudera Manager and the Cloudera Management Services.||Infrastructure node|
|Edge node||This node contains all client-facing configurations and services, including gateway configurations.||Infrastructure node|
|Worker node||This node runs all the services that are required to store blocks of data on the local hard drives, and run processing tasks against that data.||Worker node|
A high-performance network fabric connects the cluster nodes in a Cluster Data network. An additional Edge network provides an interface between the cluster and external systems and applications. See Network architecture for a detailed description of the network design.
The minimum supported configuration is eight cluster nodes, which include three Master nodes, one Utility node, one Edge node, and three Worker nodes. Dell Technologies recommends a ten-node cluster with five Worker nodes as a starting point.
