Hardware requirements and recommendations
Before you install IBM Edge Computing Manager for Clusters, review the system requirements for each of the products and the footprint sizing.
- Red Hat® OpenShift® Container Platform
- IBM Edge Computing Manager for Clusters
- Sizing for the multicluster-endpoint
- Sizing for the management hub services
Red Hat® OpenShift® Container Platform
- Red Hat® OpenShift® Container Platform installation documentation
-
OpenShift Container Platform compute or worker nodes: 16 Core | 32 GB RAM
Note: If you want to install IBM Edge Computing Manager for Devices in addition to IBM Edge Computing Manager for Clusters, you will need to add additional node resources as outlined in sizing section.
-
Storage requirements:
- For offline installation, the OpenShift Container Platform image registry requires at least 100 GB.
- The management services MongoDB and logging each require 20 GB through the storage class.
- Vulnerability advisor requires 60 GB through the storage class if enabled.
IBM Edge Computing Manager for Clusters
Sizing is available for minimal and production footprints.
Deployment topology for OpenShift and the IBM Edge Computing Manager for Clusters
| Deployment topology | Description of usage | OpenShift 4.2 node configuration |
|---|---|---|
| Minimal | Small cluster deployment |
OpenShift: IBM Edge Computing Manager for Clusters: |
| Production | Supports the default configuration of IBM Edge Computing Manager for Clusters |
OpenShift: IBM Edge Computing Manager for Clusters: |
Note: For dedicated IBM Edge Computing Manager for Clusters worker nodes, set the master, management, and proxy nodes to one OpenShift worker node, which is configured in the IBM Edge Computing Manager for Clusters Install documentation.
Note: All persistent volumes indicated below are default. You must size the volumes based on the amount of data that is stored over time.
