Feature Overview (aka. Goal Summary)  

With multi-architecture compute it is possible to add a node of a different architecture to an existing cluster. This feature will track the ability to add x86 nodes to an existing IBM Power or and IBM Z cluster as a day 2 operation.

Goals (aka. expected user outcomes)

1. Add x86 nodes as a day 2 operation to an existing OpenShift cluster on IBM Power
2. Add x86 nodes as a day 2 operation to an existing OpenShift cluster on IBM Z

Requirements (aka. Acceptance Criteria):

The methodology to instantiate additional nodes of a different architecture for this feature should be the same, if not identical to, the current method for adding Arm nodes to an existing x86 cluster

Use Cases (Optional):

Include use case diagrams, main success scenarios, alternative flow scenarios.  Initial completion during Refinement status.

Questions to Answer (Optional):

Include a list of refinement / architectural questions that may need to be answered before coding can begin.  Initial completion during Refinement status.

Out of Scope

High-level list of items that are out of scope.  Initial completion during Refinement status.

Background

Provide any additional context is needed to frame the feature.  Initial completion during Refinement status.

Customer Considerations

Provide any additional customer-specific considerations that must be made when designing and delivering the Feature.  Initial completion during Refinement status.

Documentation Considerations

Provide information that needs to be considered and planned so that documentation will meet customer needs.  Initial completion during Refinement status.

Interoperability Considerations

Which other projects and versions in our portfolio does this feature impact?  What interoperability test scenarios should be factored by the layered products?  Initial completion during Refinement status.
