Red Hat OpenShift standard resource mode requirements

Review the requirements needed to get started with the Cloudera Data Warehouse (CDW) service on Red Hat OpenShift 4.6 clusters using the standard resource mode.

Component Minimum for production workloads Recommended for production workloads
CPU 16 cores [can be achieved with 8 cores that have simultaneous multithreading (SMT) enabled] 32+ cores (can also be achieved by enabling SMT)
Memory 128 GB 384 GB
Storage (locally attached storage per Virtual Warehouse executor by using OpenShift Local Storage Operator) 600 GB per executor and Impala coordinator (SATA) 600 GB per executor and Impala coordinator (SSD/NVMe)
Storage (persistent volume storage on the file system mounts per Virtual Warehouse) Approx. 100 GB (5 x 20 GB) Approx. 100 GB (5 x 20 GB)
Network Bandwidth 1 GB/s guaranteed bandwidth to every CDP Private Cloud Base node 10 GB/s guaranteed bandwidth to every CDP Private Cloud Base node

Depending on the number of executors you want to run on each physical node, the per-node requirements change proportionally. For example, if you are running 3 executor pods per physical node, you require 384 GB of memory and approximately 1.8 TB of locally attached SSD/NVMe storage.

Security requirements

The CDW service requires the "cluster-admin" role on the OpenShift cluster in order to install correctly. The "cluster-admin" role enables namespace creation and the use of the OpenShift Local Storage Operator for local storage.
