IBM Cloud Private 3.2 for Linux (x86_64) Cloud Automation Manager 3.2.1 icp-cam-x86_64-3.2.0.tar.gz CC2IUEN

The minimum hardware requirements:

Note:

  • Ensure the processes, such as Prometheus and logstash, are running and all requirements are met.
  • Cloud Automation Manager will consume worker node resources
Cloud Automation Manager size Worker nodes vCPU Memory (GB) Notes
Single node deployment 1 12 >30  
Single node deployment without metering 1 12 >20  
High availability configuration 3 4 per node 16 GB per node  
High concurrent deployment requirements (above 10) 3 6 per node 20 GB per node 2vCPU 4 GB memory for every additional 10 concurrent deployments
Large number of deployed instances 3 5 per node 16 GB per node 1vCPU for every 15K deployments managed

The persistent storage requirements:

Note: User must create persistent volumes to store Cloud Automation Manager database and log data.

Persistent Storage Size (GB) Recommended Access Comments
cam-mongo-pv 20 GB File Storage RWX 20GB for up to 10k deployments. Add 10 GB for each additional 10k deployments.
cam-logs-pv 10 GB File Storage RWX Static
cam-terraform-pv 15 GB File Storage RWX Usage can grow or shrink
cam-bpd-appdata-pv 20 GB File Storage RWX The size grows based on the number of templates in local repository

Supported operating systems and platforms

  • Cloud Automation Manager performs ‘manage-to’ operations directly on the hypervisor and does not have any restriction on the operating system level requirement.
  • To know more about minimum system requirements for setting up and running the middleware Content Runtime within a virtual machine, see System requirements.

Other requirements

  • Internet connectivity is required for deployments to public cloud providers like IBM Cloud, Amazon EC2, and Microsoft Azure.
  • Minimum browser supported
    Firefox 52
    Chrome 57
    Safari 10.1
    Edge 16
  • Additional resources and configuration may be required based on the desired use of automation content available with Cloud Automation Manager. To understand the automation content available for use, see About Cloud Automation Manager Content.

  • Elevated privileges are required. For more information, see Prerequisites for installing Cloud Automation Manager.

The minimum hardware requirements:

Note: Demonstration/Proof of Concept This is a Size0 environment requirement. This size is suitable for a very small demonstration, trial or proof of concept. It is only suitable for a minimal workload. This size is designed to reduce the size of the microservices deployed to minimize the required hardware.

Approx resources (Agents, Data Collectors) Metrics per minute Number of VMs/hosts CPU (cores) RAM (GB) Disk (GB)
Up to 100 Up to 25000 2 12 32 100
