text: The architecture consists of the following components: 
  
  (cid:2) PowerVC: Provides Infrastructure as a Service and manages: 
  
  – IBM Power Systems (PowerVM): 
  
  (cid:129) 2 x Virtual I/O Servers: 2 cores that are configured in dedicated donated mode and 
  16 GB memory 
  
  (cid:129) 2 x Ethernet cards 
  
  (cid:129) 2 x Fibre Channel cards for each VIO Server 
  
  – Dual SAN Fabrics Brocade or Cisco 
  
  – Storage backends 
  
  (cid:2) Deployment host: RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum 
  installation. Responsible for deploying one or more OpenShift Container Platform 
  environments: 
  
  – Terraform for deploying PowerVC infrastructure (network, storage, virtual machines) 
  – OpenShift-Ansible for deploying OpenShift Container Platform 
  
  (cid:2) Load balancer: RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum 
  
  installation. HAproxy offers a single entry point for the many Red Hat OpenShift Container 
  Platform components. 
  
  **Note:**The HAProxy Load Balancer is intended to demonstrate the API server’s HA 
  mode and is not recommended for production environments. If you are deploying to a 
  cloud provider, Red Hat recommends deploying a cloud-native TCP-based Load 
  Balancer or take other steps to provide a highly available Load Balancer.
