Answers to questions that are related to installation of IBM Fusion HCI.

  1. Is it possible to configure custom ingress certificate?
    Yes, it can be done at installation time by using the IBM Fusion HCI installer or manually as Day 2 following Red Hat documentation.

  2. Is it possible to setup cluster-wide proxy?
    Yes, you can setup cluster-wide proxy.

  3. Is offline installation supported for air-gapped data centers?
    Yes, offline installation is supported for air-gapped data centers.

    It is common in production to have a cluster that does not have internet access (air gap, offline, disconnected). In such cases, you can still install the IBM Fusion HCI solution in your air gap environment. The experience is the same as an online installation where you use the IBM and Red Hat entitled registries. However, you must do additional steps to mirror images to your enterprise registry. For more information about mirroring images, see End-to-end mirroring images of IBM Fusion HCI and its services to the enterprise registry.

  4. Is Quay registry supported for air gap installation?
    Yes, from 2.8 release onwards, support is available for Quay registry.

  5. Is self-signed certificate registry support available for air gap installation?
    Yes, from 2.8 release onwards, support is available for registries with self-signed certificate.

  6. What are the stages of the IBM Fusion HCI installation and approximately how long does each stage take?
    Installation stage Approximate time duration
    Stage 1: Network configuration 12 minutes
    Stage 2: IBM Fusion HCI software installation 90 minutes
