FEAT: Integrate CSM Functionalities into OCHAMI for HPC Cluster Management

[Masber]

Manta currently supports operations for both CSM and OCHAMI management planes to deploy HPC clusters. However, the OCHAMI management plane lacks some critical functionalities needed by system administrators. This ticket focuses on enhancing the OCHAMI management plane by reusing and integrating selected CSM functionalities. The goal is to provide a unified, feature-complete experience for administrators managing HPC clusters on OCHAMI.

Objectives:

Identify and list the CSM functionalities that are missing in OCHAMI.

Design an integration plan to reuse these functionalities within the OCHAMI management plane.

Ensure a seamless experience for system administrators managing HPC clusters via Manta.

Tasks:

Analysis & Planning:

    Review the current functionalities provided by CSM.

    Identify the specific features required by OCHAMI that are missing.

    Define clear criteria and mapping for which CSM functionalities will be integrated into OCHAMI.

Design Integration Approach:

    Architect the integration plan so that Manta can determine which management plane (CSM or OCHAMI) is available and then delegate or translate operations accordingly.

    Define any necessary API adapters or middleware components to bridge differences between the two management planes.

    Ensure that the integration maintains security, performance, and error handling standards.

Development:

    Implement the integration layer to allow OCHAMI to reuse the selected CSM functionalities.

    Modify CLI command handlers to dynamically switch to the appropriate management plane based on user context.

    Update error messages, logs, and documentation to reflect the new functionality in OCHAMI clusters.

Testing & Validation:

    Write unit and integration tests to ensure that the reused functionalities work as expected in the OCHAMI environment.

    Validate that HPC cluster deployment operations work seamlessly across both management planes.

    Conduct end-to-end tests simulating real-world scenarios from a system administrator’s perspective.

Documentation:

    Update the CLI documentation to include the new integrated functionalities available for OCHAMI.

    Provide a clear mapping of which CSM functionalities are available in OCHAMI and any caveats or differences.

    Include examples and usage scenarios in the documentation.

Acceptance Criteria:

A comprehensive mapping and plan for integrating CSM functionalities into the OCHAMI management plane is documented.

Manta seamlessly delegates missing OCHAMI functionalities to the corresponding CSM operations.

Integration is thoroughly tested, with unit and integration tests passing.

Updated documentation clearly outlines the integrated functionalities and provides usage examples.

The solution is validated in a staging environment by system administrators managing HPC clusters on OCHAMI.
