Sizing for a hybrid deployment

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

Hardware sizing for a hybrid 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.

Table 1. Detailed supported throughput rates for given sized environments.
General sizing information
Category	Resource	Trial	Production
Event Management sizing information
Event Rate Throughput	Steady state events per second	20	50
Event Rate Throughput	Burst rate events per second	100	500
Topology Management sizing information
System size	Approx. 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
Environment options	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.
Total hardware requirements Netcool Operations Insight services only
Category	Resource	Trial	Production
Resource requirements	Nodes count	3	6
	vCPUs	24	78
	Memory (GB)	72	192
	Disk (GB)	360	720
Persistent storage requirements (Gi)		585	3100
Total disk IOPS requirements		850	5950

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.

Added ASM disabled numbers in parentheses
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	90
	Memory (GB)	88	240
	Disk (GB)	480	1080
Persistent storage requirements (Gi)		585	3100
Total disk IOPS requirements		850	5950

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.
Hardware Sizing Requirements
Category	Resource	Trial	Production
OpenShift Control Plane Resource requirements per control plane	Nodes count	1	3
	vCPUs	4	4
	Memory (GB)	16	16
	Disk (GB)	120	120
Netcool Operations Insight components - suggested configuration
OpenShift compute (worker) nodes Resource requirements per compute node	Nodes count	3	6
	vCPUs	8	13
	Memory (GB)	24	32
	Disk (GB)	120	120
Persistent storage minimum requirements (Gi)	Cassandra	250	1500
	Kafka	150	600
	Zookeeper	10	30
	Elasticsearch	150	900
	File-observer	5	10
	CouchDB	20	60
Persistent storage minimum IOPS requirements	Cassandra	300	1800
	Kafka	200	1200
	Zookeeper	50	150
	Elasticsearch	200	2400
	File-observer	50	100
	CouchDB	50	300

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.
