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:
The following table lists the minimum and recommended compute (processor), memory, storage, and network bandwidth required for each OpenShift or ECS worker node using the Standard Resource Mode for production use case. Note that the actual node still needs some extra resources to run the operating system, Kubernetes engine, and Cloudera Manager agent on ECS.
|CPU per worker||16 cores [or 8 cores or 16 threads that have Simultaneous Multithreading (SMT) enabled]||32+ cores (can also be achieved by enabling SMT)|
|Memory per worker||128 GB per node||384 GB* per node|
FAST (Fully Automated Storage Tiering) Cache - Locally attached SCSI device(s) on every worker.
Preferred: NVMe and SSD.
OCP uses Local Storage Operator. ECS uses Local Path Provisioner.
|1.2 TB* SATA, SSD per host||1.2 TB* NVMe/SSD per host|
Persistent Volume (PV) Block Storage.
On OCP, block from a Container Storage Interface (CSI)-compliant block provider, such as OpenShift Container Storage.
ECS uses an embedded distributed block provider that aggregates local disks of workers.
Other Data Services additionally have added capacity requirements on this service.
