This accelerator deploys OpenShift Container Platform V4.3.1 cluster in HA mode with HA Proxy.
By default, the accelerator deploys two helper nodes, one bootstrap node, three master nodes, and four worker nodes. However, you can deploy more master nodes and worker nodes by using the Scaling Policy that is defined on those nodes. The accelerator has set default CPU, RAM, and Storage. You can change these at deployment time based on business requirements. Detailed system requirements for IBM Cloud Pak for Data can be found at Hardware requirements and recommendations for IBM Cloud Pak for Data.
Note: Cloud Pak for Data on OpenShift Container Platform - HA accelerator is only supported on single system and cloud groups that have a "Deployment type" of "Single Cloud" or "Multi Cloud".
Table 1: Hardware specifications and system requirements
| Host | Specifications |
|---|---|
| Master Host | Base OS: RHEL Core OS |
| 16 vCPU for each master node (more vCPU can be configured while you deploy the accelerator that is based on your requirement). | |
| 16 GB RAM for each master node(more memory can be configured while you deploy the accelerator that is based on your requirement). | |
| Default 3 master nodes | |
| Compute Host | Base OS: RHEL Core OS |
| 16 vCPU for each compute node (more vCPU can be configured while you deploy the accelerator that is based on your requirement). | |
| 64 GB RAM for each compute node (more memory can be configured while you deploy the accelerator that is based on your requirement). | |
| Default 3 compute nodes | |
| Primary Helper | Base OS: RHEL 7.7 |
| 4 vCPU (more vCPU can be configured while you deploy the accelerator that is based on your requirement). | |
| 16 GB RAM (more memory can be configured while you deploy the accelerator based on your requirement). | |
| The following disks are defined by this accelerator: | |
| Disk with mount point /export and size 200 GB, of type ext4. It is used as an OpenShift image registry storage. | |
| Disk with mount point /cs and size 1024 GB, of type ext4. It is used as NFS storage for deploying IBM Cloud Pak for Data. | |
| Disk with mount point / and size 300 GB, of type ext4 | |
| Secondary Helper Node | Base OS: RHEL 7.7 |
