System requirements for high availability
This information provides guidance on requirements for high availability deployments of IBM® Cloud Pak for Integration.
High availability characteristics
Deploy the cluster in a HA configuration with at least 3 workers. Deploy the MQ services from the helm charts and they will be highly available by default.
|Product||HA Approach||Min Worker Nodes in Cluster|
|API Lifecycle and Management||Quorem||3|
|High Speed File Transfer||Quorem||3|
The following table lists the cores required for minimal deployment and high availability deployment of the core product and related capabilities.
|Component||Cores Provisioned non-HA||Cores Provisioned HA||Nodes|
Master, Proxy, Management nodes
|Platform Navigator||0.5||1.5||At least 3 shared worker nodes|
|MQ Messaging||1 *4||1 or 2 *4||At least 2 shared worker nodes|
|API Lifecycle and Management||12||48||At least 3 shared worker nodes|
|Application Integration||1.1||1.1 or 2.1 *5||At least 2 shared worker nodes|
|Aspera High Speed File Transfer||4||12||At least 3 shared worker nodes|
|Event Streams||20.8 *1||20.8 *1||At least 3 shared worker nodes|
- See https://ibm.github.io/event-streams/installing/prerequisites/ Min config is highly available 4 CPUs x3 pods for kafka. Only kafka pods consume VPCs. Provisioned number adds CPUs for the other pods mentioned on that link.
- See https://www.ibm.com/support/knowledgecenter/en/SSBS6K_3.2.0/supported_system_config/hardware_reqs.html. one (boot/master/proxy)(8 CPU) + one Management (8 CPU) = 16
- 3x (boot/master/proxy)(8 CPU) + 2x Management (8 CPU) = 40
- MQ minimum is 1 CPU core. (from helm chart) License ratio is 0.5. HA configuration can be either node failover which requires only 1 cores or active/active which requires 2
- App Connect min configuration is 1 CPU core (from helm chart). License ratio is 3. HA configuration can be either node failover which requires only 1 cores or active/active which requires 2. Control plane requires 0.1 CPU – - not chargeable
- From https://www.ibm.com/software/reports/compatibility/clarity/softwareReqsForProduct.html manager:4, Analytics:2, portal: 2, API Gateway: 4 However APIC recommend says 4+4+4+4=16 for minimum productive use
