Red Hat OpenShift Container Platform hardware requirements
Cloudera on premises 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 Cloudera.
The sizing of the OpenShift cluster depends on:
- The OpenShift cluster setup on the master nodes
- Application workloads deployed on the 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 (SSD support only) |
|---|---|---|---|
| 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 or Cloudera AI data services workloads, you need to ensure that you meet the minimum requirements for each of those Data Services.
You can install Cloudera Data Services on premises in a low resource
mode for Cloudera Data Warehouse workloads. For more information about
