System requirements of a hybrid deployment

Edit online

Learn about the system requirements for a hybrid deployment of IBM® Netcool® Operations Insight®.

For detailed system requirements on the on-premises and cloud portions of a hybrid deployment, search for version 1.6.13 of the Netcool Operations Insight product in the Software Product Compatibility Reports website: https://www.ibm.com/software/reports/compatibility/clarity/softwareReqsForProduct.htmlexternal link

The cloud portion of a hybrid installation, the cloud native components on Red Hat® OpenShift® Container Platform, has the following requirements.

Browser support

The current version of Netcool Operations Insight, 1.6.13, is compatible with several browsers. For more information, see the Web Browsers section on the Supported Software tab in the 1.6.13 report: SPCR for version 1.6.13 Launch out icon

Red Hat OpenShift Container Platform support

The current version of Netcool Operations Insight, 1.6.13, is compatible with versions 4.12, 4.13, 4.14, 4.15, and 4.16.4 of Red Hat OpenShift Container Platform. For information about Red Hat OpenShift Container Platform support dates, see Life Cycle Dates external link. The documentation links point to version 4.15 of the Red Hat OpenShift documentation external link.
Note: When you upgrade Red Hat OpenShift, do not drain all the nodes. Instead, rely on the PodDisruptionBudgets (PDBs) to avoid any service disruption.

Platform support

Netcool Operations Insight on OpenShift is supported on x86 platforms.

A Netcool Operations Insight on OpenShift deployment is also supported on the following platforms:

  • Red Hat OpenShift Service on AWS (ROSA)
  • Red Hat OpenShift on Google Cloud Platform (GCP)
  • Azure Red Hat OpenShift (Microsoft ARO)
  • IBM Red Hat OpenShift Kubernetes Service (ROKS), which can be provisioned from the IBM Cloud® catalog: https://cloud.ibm.com/kubernetes/catalog/OpenShiftcluster

Sizing

Storage

For more information about storage options for the cloud components of a hybrid deployment, see Hybrid storage.

Network requirements

The Red Hat OpenShift Networking network plugin is selected during installation (OpenShiftSDN or OVNKubernetes). This value cannot be changed after cluster installation. Red Hat OpenShift Container Platform uses the OVNKubernetes network plugin by default. From Red Hat OpenShift Container Platform 4.12 onwards, the OVNKubernetes Container Network Interface (CNI) uses the 100.64.0.0/16 subnet internally. For more information, see About the OVN-Kubernetes network plugin external icon in the Red Hat OpenShift Container Platform documentation.

If your existing network infrastructure overlaps with the 100.64.0.0/16 IPv4 subnet, you can specify a different IP address range for internal use by OVNKubernetes. You must ensure that the IP address range does not overlap with any other subnet used by your Red Hat OpenShift Container Platform installation. The IP address range must be larger than the maximum number of nodes that can be added to the cluster. For more information, see Cluster Network Operator external icon in the Red Hat OpenShift Container Platform documentation.
