Sizing for a Netcool Operations Insight on Red Hat OpenShift deployment

Edit online

Learn about the sizing requirements for a full Netcool® Operations Insight® on OpenShift® deployment.

Hardware sizing for a full deployment on Red Hat OpenShift

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: Red Hat® OpenShift user-provisioned infrastructure is not sized as part of this sizing. Please refer to Red Hat OpenShift documentation for more details.

General sizing information
Category Resource Trial Production
Event Management sizing information
Event Rate Throughput Steady state events per second 20 50
Burst rate events per second 100 500
Topology Management sizing information
System size Approximate resources 200,000 5,000,000
Metric Management sizing information
System size Number of metrics 10,000 100,000
Environment options Minimum metric granularity 5 minutes 5 minutes
High availability No Yes
Runbook Automation sizing information
Fully automated runbooks Run per second 1 2
Note: 4 runs per second for a large production environment
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 additional work node is required for node maintenance.
Table 2. This table shows the hardware requirements attributed to the Netcool Operations Insight footprint deployed on Red Hat OpenShift. This table is useful for sizing when there is a Red Hat OpenShift cluster already installed but there is a need to add worker/compute nodes to it to accommodate Netcool Operations Insight.

vCPUs 24 84
Memory (GB) 72 210
Disk (GB) 360 720
Persistent storage requirements (Gi)   611 3146
Total disk IOPS requirements   1200 6650
Table 3. This table shows the total hardware requirements for a Netcool Operations Insight (including Event Management & Topology Management) system deployed on a Red Hat OpenShift cluster, including both the Netcool Operations Insight and Red Hat OpenShift related hardware needs. This table is useful for sizing when there is a need to create a new Red Hat OpenShift cluster to deploy the full Red Hat OpenShift and Netcool Operations Insight stack.
Total requirements Netcool Operations Insight including Red Hat OpenShift Control plane and Compute nodes
Category Resource Trial Production
Resource requirements Nodes count 4 9
vCPUs 28 96
Memory (GB) 88 258
Disk (GB) 480 1080
Persistent storage requirements (Gi)   611 3146
Total disk IOPS requirements   1200 6650
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 Master and Worker nodes, along with the recommended configuration for the disk volumes associated with each persisted storage resource.

Additional 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 39 GB.
  • Bastion host method - the local registry must have at least 39 GB of storage space.
  • Portable compute device method - the local registry must have at least 39 GB of storage space.
  • Portable storage device method - the local registry must have at least 39 GB of storage space.
