Small production hardware cluster requirements
You must have cluster administrator
(cluster-admin) privileges in order to set up Guardium®
Insights. In addition to this and the OpenShift® Container
Platform base hardware
requirements (also
included in the below table), Guardium
Insights requires
worker and data nodes that include the requirements of RHEL and IBM Cloud Pak®
foundational services. This topic outlines the requirements for
small productions.
Attention: It is recommended that Guardium
Insights be installed in its own OpenShift cluster.
Graphical representation of the requirements
This image represents the small production hardware cluster requirements. These requirements are detailed in the below sections.
Small production hardware cluster requirements
| Number of nodes | CPU per node | RAM per node | System disk per node | |
|---|---|---|---|---|
| OpenShift base requirements | 3 | 8 cores | 16 GB | 120 GB |
| Guardium Insights nodes | 3 | 16 cores | 64 GB | 120 GB |
| Guardium Insights nodes | 2 Note: This larger set of Guardium
Insights nodes should be used as your Db2® data nodes when using the preInstall.sh
-h
option. |
16 cores | 64 GB | 120 GB |
| Kubernetes storage | n/a | n/a | n/a | 14 TB |
Important: If you are using Openshift Data Foundation (previously OpenShift Container Storage) for storage, there are additional hardware
requirements. See Validated storage options for more information.
Requirements outside the cluster
| CPU | RAM | System disk | |
|---|---|---|---|
| Load balancer for OpenShift Container Platform | n/a | n/a | n/a |
| Bootstrap server (required temporarily during installation) | 4 cores | 16 GB | 80 GB |
| Bastion server (used for DCHP, DNS, NTP - and for hosting various files and tools that are used for provisioning the bootstrap server) | 6 cores | 24 GB | 250 GB |
| LDAP server | n/a | n/a | n/a |
Note: Requirements for the LDAP server and OpenShift load balancer vary. You should set the CPU and RAM
for these according to the needs of your business.
Persistent storage for small production hardware clusters

CPU/Network/Storage requirements
| Requirement | |
|---|---|
| CPU | 2.4 GHz or higher (AVX2 instruction set is required). |
| Network | 10 GB Ethernet (GbE) between all nodes, including storage. |
| Storage | Network attached (SAN) SSD at 3000 MB/sec IO (see the above section to learn the amount of storage that is required). |
