OpenShift Container Platform for HA accelerator
This accelerator deploys OpenShift nodes on separate hosts. The accelerator deploys two helper nodes, three master nodes, and two worker nodes by default. However, you can deploy more worker nodes by using the Scaling Policy that is defined on those nodes.
Notes:
OpenShift Container Platform 4 - HAaccelerator is only supported on a single system and cloud groups that have a "Deployment type" of "Single Cloud" or "Multi Cloud".
Table 1: Hardware specifications
| Host | Specification |
|---|---|
| Master Node | In Cloud Pak System Version 2.3.6, Base OS: RHCOS 4.18. OpenShift Container Platform 4.18 is supported on Red Hat Enterprise Linux (RHEL) 8.10 as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.18. . In Cloud Pak System Version 2.3.3.6, Base OS: RHCOS 4.12. OpenShift Container Platform 4.12 is supported on Red Hat Enterprise Linux (RHEL) 8.6 as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.12. |
| 16 vCPU for each master node (extra vCPU can be configured when you deploy a accelerator that is based on your requirement). | |
| 16 GB RAM for each master node (extra memory can be configured when you deploy a accelerator that is based on your requirement). | |
| Default 3 master nodes. You cannot scale master nodes before or after the deployment. | |
| Worker Node | In Cloud Pak System Version 2.3.6, Base OS: RHCOS 4.18.0. In Cloud Pak System Version 2.3.3.6, Base OS: RHCOS 4.10.16 |
| 4 vCPU for each worker node (extra vCPU can be configured when you deploy a accelerator that is based on your requirement). | |
| 8 GB RAM for each worker node (extra memory can be configured when you deploy a accelerator that is based on your requirement). | |
| By default, the worker node is set to 2. You can also set it to a minimum of 2 or can scale up to a maximum of 50 nodes. | |

| The following disks are being defined by this template: | |
| Disk with mount point /export and size 110 GB, of type ext4 | |
| Disk with mount point / and size 110 GB, of type ext4 | |
| Disk with mount point /cps and size 210 GB, of type ext4 for NFS persistent storage for applications | |
| Secondary Helper node | In Cloud Pak System Version 2.3.6, Base OS: RHEL 8.10. In Cloud Pak System Version 2.3.3.6, Base OS: RHEL 8.6 |
| 4 vCPU (extra vCPU can be configured when you deploy a accelerator that is based on your requirement). | |

| Disk with mount point / and size 60 GB, of type ext4. | |
| Bootstrap node | In Cloud Pak System Version 2.3.6, Base OS: RHCOS 4.18.0. In Cloud Pak System Version 2.3.3.6, Base OS: RHCOS 4.10.16 |
| 4 vCPU (extra vCPU can be configured when you deploy a accelerator that is based on your requirement). | |
| 16 GB RAM (extra memory can be configured when you deploy a accelerator that is based on your requirement). | |
| Note: Though the bootstrap node gets released after deployment, ensure you have the necessary resources for it. |
