Get started with OpenShift and Embedded Container Service standard resource mode requirements
Review the memory, storage, and hardware requirements for getting started with the Cloudera Data Warehouse (CDW) service in standard resource mode on Red Hat OpenShift 4.6 and Embedded Container Service.
To get started with the CDW service on standard resource mode, make sure you have fulfilled the following requirements:
- CDP Cloudera Manager must be installed and running.
- CDP Private Cloud must be installed and running. See Private Cloud Installation Overview and Requirements for more details.
- An environment must have been registered with Management Console on the private cloud. See CDP Private Cloud Environments for more details.
- In addition to the general requirements listed in the Private Cloud Installation Requirements documentation, CDW also has the following minimum memory, storage, and hardware requirements for each OpenShift worker node 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.
