If the resources that are currently allocated for the NSX Application Platform reach the threshold values set by the system, the system generates an alarm. To accommodate the needs of the NSX Application Platform core services, you must scale out the platform.
Use the following table to determine the minimum number of nodes required to scale out the core services and to learn what improvements are obtained after successfully scaling out the core services.
Core Service Name |
Minimum # of nodes required for a Scale Out operation |
What improves after scaling out the service |
---|---|---|
Messaging |
At least five nodes |
Scaling out the Messaging service increases messaging broker instance in your TKG Cluster on Supervisor or upstream Kubernetes cluster. |
Analytics |
At least four nodes |
Scaling out the Analytics service increases the overall data pipeline processing throughput of the NSX Intelligence features. |
Data Storage |
At least eight nodes |
Scaling out Data Storage service adds more object storage broker instances in your TKG Cluster on Supervisor or upstream Kubernetes cluster. |
Metrics |
At least three nodes |
Scaling out the Metrics service increases the metrics data processing throughput of the NSX Metrics feature. |
Select the All check box in the Scale Out dialog box and let the system decide which of the cores services must be scaled out. Arbitrarily scaling out a core service category might lead to more resources being used without achieving any performance improvement. Consult the VMware support team before scaling out a single core service category.
Prerequisites
All existing nodes in your TKG Cluster on Supervisor or upstream Kubernetes cluster must be in a healthy and ready state before you can scale out the NSX Application Platform.
Before proceeding with the scale-out procedures, ensure that your infrastructure administrator has already allocated the minimum number of nodes required for scaling out the NSX Application Platform services.
