Sizing for a hybrid deployment

Edit online

Learn about the sizing requirements for a hybrid deployment on Red Hat® OpenShift® Container Platform.

Hardware sizing for a hybrid deployment on Red Hat OpenShift Container Platform

Note: vCPU is defined as when one x86 CPU splits each of its physical cores into virtual cores (vCPU). It is assumed that one x86 CPUs physical core can be split into two logical vCPUs.

Trial sizes are provided for limited scenarios, such as proof of concept demonstrations. Do not use trial sizes in a test or production environment.

Note: The sizing tables provide a large production sizing option, which is not currently supported at installationation time. If you have requirements for a large production sizing installation, contact your local support team.
Note: Red Hat OpenShift Container Platform user-provisioned infrastructure is not sized as part of this sizing. Refer to Red Hat OpenShift Container Platform documentation for more details.
Note: If Red Hat OpenShift Container Platform is installed on VMware virtual machines, set the value of the sched.cpu.latencySensitivity parameter to high.

Note: Event rates for Cloud Native Event Analytics assume a deduplication rate of 6 to 1 (17% unique events) on the ObjectServer.
Note: The requirements are the minimum CPU, memory, and storage requirements for Netcool® Operations Insight® services only. If these minimum requirements are not in place, do not install the product.
Note: To avoid outages, a minimum of one extra work node is required for node maintenance.
Table 2. This table shows the hardware requirements that are attributed to the Netcool Operations Insight footprint deployed on Red Hat OpenShift Container Platform. This table is useful for sizing when a Red Hat OpenShift Container Platform cluster is already installed, but there is a need to add worker or compute nodes to it to accommodate Netcool Operations Insight.
Total hardware requirements Netcool Operations Insight services only
Category Resource Trial Production Large production sizing
Resource requirements Minimum node count 3 7 11
vCPUs (Total) 24 98 147
Memory (GB)(Total) 72 224 368
Disk (GB)(Total) 360 840 1,260
Netcool Operations Insight Persistent storage requirements (Gi)   635 7,182 12,432
Total disk IOPS requirements*   5,000 10,000 20,000

*You might need to convert IOPS values, depending on your specific network storage solution and cloud vendor environment. For example, when you provision block storage for Virtual Private Cloud data volumes, you specify an IOPS profile that best meets your storage requirements. For more information, see the IOPS tiers external icon topic in the IBM Cloud® Virtual Private Cloud documentation. The IOPS specification that you provision should be suitable for I/O-intensive database workloads.

Table 3. This table shows the total hardware requirements for a Netcool Operations Insight system deployed on a Red Hat OpenShift Container Platform cluster, including both the Netcool Operations Insight and Red Hat OpenShift Container Platform related hardware needs. This table is useful for sizing when you need to create a new Red Hat OpenShift Container Platform cluster to deploy the full Red Hat OpenShift Container Platform and Netcool Operations Insight stack.

Note: These requirements do not include CPU and memory resources for hosting a storage provider, such as Red Hat OpenShift Data Foundation (previously called Red Hat OpenShift Container Storage) or Portworx. These storage providers can require more nodes, resources, or both, to run. The extra resources that are needed can vary based on your selected storage provider.
Table 4. This table illustrates the recommended resource allocation for the Red Hat OpenShift Container Platform Control plane and worker nodes, along with the recommended configuration for the disk volumes associated with each persisted storage resource.

Extra requirements for offline (airgap) deployments

If you are installing in an air-gapped environment (offline), you must ensure that you have adequate space to download the Netcool Operations Insight on Red Hat OpenShift images to a local registry in your offline environment. The Netcool Operations Insight on Red Hat OpenShift images total 44 GB.
  • Bastion host method - the local registry and the bastion host must each have at least 44 GB of storage space.
  • Portable method - the local registry and the portable device must have at least 44 GB of storage space.
