High availability

The Cloud Pak for Data System architecture is based on high availability. The base system comprises eight nodes:
  • Three control nodes - If a control node fails, the workflow is automatically shifted to another control node.
  • Three worker nodes - If all three fail or are unavailable, a control node can become a worker node.
  • Two unset nodes - these can also be used if there are failures.
System expansion is available. You can buy and add extra nodes as described in Adding new nodes to the system.
