Red Hat OpenShift Container Platform hardware requirements

Cloudera Data Platform (CDP) Private Cloud requires hardware for a dedicated OpenShift Container Platform (OCP) cluster. An OpenShift cluster consists of several master nodes for managing OpenShift and many worker nodes for running your application on CDP.

The sizing of the OpenShift cluster depends on:
  • The OpenShift cluster setup on the master nodes
  • Application workloads deployed on the worker nodes
The CDP Private Cloud Experiences is installed on the OpenShift worker nodes.

The following table lists the hardware requirements for each node type. You require at least 3 minimum OpenShift Master Nodes + 1 Cluster System Admin Host (CSAH) Node + 1 Bootstrap Node. You need worker nodes based on your application workload requirements.

Role CPU cores Memory Storage
Master 4 16 GB 120 GB
CSAH 4 64 GB 200 GB
Bootstrap 4 16 GB 120 GB
Worker Depends on your workloads Depends on your workloads Depends on your workloads

Additionally, if you plan to run Cloudera Data Warehouse (CDW) or Cloudera Machine Learning (CML) experience workloads, you need to ensure that you meet the minimum requirements for each of those Experiences.

You can install CDP Private Cloud Experiences in a low resource mode for Cloudera Data Warehouse (CDW) workloads.
