System requirements

All the Cloud Pak containers are based on Red Hat Universal Base Images (UBI), and are Red Hat and IBM certified. To use the Cloud Pak images, the administrator must make sure that the target cluster on Red Hat OpenShift Container Platform has the capacity for all the capabilities that you plan to install.

For each stage in your operations (a minimum of three stages is expected "development, preproduction, and production"), you must allocate a cluster of nodes before you install the Cloud Pak. Development, preproduction, and production are stages that are best run on different compute nodes. To achieve resource isolation, each namespace is a virtual cluster within the physical cluster and a Cloud Pak deployment is scoped to a single namespace. High-level resource objects are scoped within namespaces. Low-level resources, such as nodes and persistent volumes, are not in namespaces.

Note: Use the shared_configuration.sc_deployment_license parameter to define the purpose of the "custom" deployment type (shared_configuration.sc_deployment_type). Valid values are production and non-production.

The Detailed system requirements page provides a cluster requirements guideline for IBM Cloud Pak® for Business Automation. To find information on the supported versions of OpenShift Container Platform for example, open the rendered report for 23.0.2 and go to the Containers tab.

The minimum cluster configuration and physical resources that are needed to run the Cloud Pak include the following elements:
  • Hardware architecture: Intel (amd64 or x86_64 the 64-bit edition for Linux® x86) on all platforms, Linux on IBM Z, or Linux on Power.
  • Node counts: Dual compute nodes for nonproduction and production clusters. A minimum of three nodes is needed for medium and large production environments and large test environments. Any cluster configuration needs to adapt to the size of the projects and the workload that is expected.

Based on your cluster requirement, you can pick a deployment profile (sc_deployment_profile_size) and enable it during installation. Cloud Pak for Business Automation provides small, medium, and large deployment profiles. You can set the profile during installation, in an update, and during an upgrade.

The default profile is small. Before you install the Cloud Pak, you can change the profile to medium or large. You can scale up or down a profile anytime after installation. However, if you install with a medium profile and another Cloud Pak specifies a medium or large profile then if you scale down to size small, the profile for the foundational services remains as it is. You can scale down the foundational services to small only if no other Cloud Pak specifies a medium or large size.
Attention: The values in the hardware requirements tables were derived under specific operating and environment conditions. The information is accurate under specific conditions, but results that are obtained in your operating environments might vary significantly. Therefore, IBM cannot provide any representations, assurances, guarantees, or warranties regarding the performance of the profiles in your environment.

It is recommended that you set the IBM Cloud Platform UI (Zen) service to the same size as Cloud Pak for Business Automation. The possible values are small, medium, and large.

The following table describes each deployment profile.

Table 1. Deployment profiles and estimated workloads

  • Processes 1,000,000 documents
  • Processes 125,000 human workflows
  • Processes 2 million Straight Thru Processes processes
  • Processes 7 million Straight Thru Service Flows

You can use custom resource templates to update the hardware requirements of the services that you want to install.

The following sections provide the default resources for each capability. For more information about the minimum requirements of foundational services, see Hardware requirements and recommendations for foundational services.

Note: The system requirements for small, medium, and large profiles are derived under specific operating and environment conditions. Due to the differences in hardware, networking, and storage, the resources vary for each workload in different environments. It is important that you run a performance test with peaked workload in a Test or UAT environment. Monitor the resource usage (for example CPU and memory) to determine the resource usage for each component. Based on the resource usage, make changes to CPU request, CPU limit, memory request, and memory limit in the custom resource for each component.

Important:
  • Document Processing - The Deep Learning optional container can use NVIDIA GPU if it is available. NVIDIA is the only supported GPU for Deep Learning in the Document Processing pattern. The GPU worker nodes must have a unique label, for example ibm-cloud.kubernetes.io/gpu-enabled:true. You add this label value to the deployment script or to the YAML file of your custom resource when you configure the YAML for deployment. To install the NVIDIA GPU operator, follow these installation instructions. For high-availability, you need a minimum of 2 GPU so that 2 replicas of Deep Learning pods can be started. You can change the replica to 1 if you have 1 GPU on the node.
  • For Document Processing, the CPU of the worker nodes must meet TensorFlow AVX requirements. For more information, see Hardware requirements for TensorFlow with pip.
Note:
  • Document Processing requires databases for project configuration and processing. These databases must be Db2 or PostgreSQL. The hardware and storage requirements for the databases depend on the system load for each document processing project.
  • The previous table shows the requirements if deep learning object detection is enabled. If you process fixed-format documents only, you might improve performance by disabling deep learning object detection. For more information about the system requirements for Document Processing engine components in this scenario, see IBM Automation Document Processing system requirements when disabling deep learning object detection for fixed-format documents.
  • If you deploy with only the document_processing pattern, you can reduce the sizing for some of the required components. For more information, see IBM Automation Document Processing system requirements for a light production deployment (document_processing pattern only).
  • It is recommended to use 70% of the available space for projects, for example if you have 5000 Mb, use 3500 Mb for your projects. Because the model size is 153 Mb, it means you must create a maximum of 22 projects. If you want to set up more than 22 projects, you must increase the ephemeral storage for both the Deep Learning and Processing Extraction containers.
  • The OCR engine 2 Runtime container enables support for low-quality documents and handwriting recognition when the ca_configuration.ocrextraction.use_iocr parameter is set to auto or all.
  • OCR engine 2 Extraction is an optional container that is used to make gRPC requests to the OCR engine 2 Runtime service, and you deploy it by setting the ca_configuration.ocrextraction.use_iocr parameter to auto or all.

Note: Business Automation Insights relies on Kafka, and Elasticsearch from Foundational Services. Business Automation Insights also creates the bai-setup and bai-core-application-setup Kubernetes jobs and requests 200m for CPU and 350Mi for memory. The CPU and memory limits are set equal to the requests. The pods of these Kubernetes jobs run for a short time at the beginning of the installation, then complete, thus freeing the resources.

Business Automation Workflow also creates some jobs that request 200m CPU and 128Mi Memory:
  • basimport-job is created only with Business Automation Studio.
  • case-init-job
  • db-init-job
  • content-init-job

Task Manager 500 1000 1536 1536 1 No
Note: Not all containers are used in every workload. If a feature the Content Services GraphQL API is not used, that container requires less resources or is optionally not deployed.

In high-volume indexing scenarios, where ingested docs are full-text indexed, the CSS usage can exceed the CPE usage. Sometimes, this might be 3 - 5 times larger.

For optional processing such as thumbnail generation or text filtering, at least 1 GB of native memory is required by the CPE for each. If both types of processing are expected, add at least 2 GB to the memory requests/limits for the CPE.

With the processing of content, resources required increase with the complexity and size of the content. Increase both memory and CPU for the CPE and CSS services to reflect the type and size of documents in your system. Resource requirements might also increase over time as the amount of data in the system grows.

Important:
  • Document Processing - The Deep Learning optional container can use NVIDIA GPU if it is available. NVIDIA is the only supported GPU for Deep Learning in the Document Processing pattern. The GPU worker nodes must have a unique label, for example ibm-cloud.kubernetes.io/gpu-enabled:true. You add this label value to the deployment script or to the YAML file of your custom resource when you configure the YAML for deployment. To install the NVIDIA GPU operator, follow these installation instructions. For high-availability, you need a minimum of 2 GPU so that 2 replicas of Deep Learning pods can be started. You can change the replica to 1 if you have 1 GPU on the node.
  • For Document Processing, the CPU of the worker nodes must meet TensorFlow AVX requirements. For more information, see Hardware requirements for TensorFlow with pip.
Note:
  • Document Processing requires databases for project configuration and processing. These databases must be Db2 or PostgreSQL. The hardware and storage requirements for the databases depend on the system load for each document processing project.
  • The previous table shows the requirements if deep learning object detection is enabled. If you process only fixed-format documents, you might improve performance by disabling deep learning object detection. For more information about the system requirements for Document Processing engine components in this scenario, see IBM Automation Document Processing system requirements when disabling deep learning object detection for fixed-format documents.
  • If you deploy with only the document_processing pattern, you can reduce the sizing for some of the required components. For more information, see IBM Automation Document Processing system requirements for a light production deployment (document_processing pattern only).
  • It is recommended to use 70% of the available space for projects, for example if you have 5000 Mb, use 3500 Mb for your projects. Because the model size is 153 Mb, it means you must create a maximum of 22 projects. If you want to set up more than 22 projects, you must increase the ephemeral storage for both the Deep Learning and Processing Extraction containers.
  • The OCR engine 2 Runtime container enables support for low-quality documents and handwriting recognition when the ca_configuration.ocrextraction.use_iocr parameter is set to auto or all.
  • OCR engine 2 Extraction is an optional container that is used to make gRPC requests to the OCR engine 2 Runtime service, and you deploy it by setting the ca_configuration.ocrextraction.use_iocr parameter to auto or all.
