This section lists the deployment requirements for demo and HA footprints.
The following table shows the infrastructure requirements for each deployment platform in terms of CPU, RAM, and the expected number of nodes. Validation of available resources must be performed before installation to ensure that the required capacity is in place. In addition to CPU and RAM requirements, the table also provides information on the expected storage requirements. Storage requirements are calculated based on footprint size and desired raw metric retention period. Use the storage size values for the amount of storage that is expected for persistent data. Persistent volumes are allocated for different services with the backing of persistent storage supported by each of the deployment platforms. Finally, the table also provides some high-level operation metrics that can be used as guidance to determine the suitability supported by each of the given footprints.

- Refer VMware Telco Cloud Service Assurance sizing sheet document for planning the VMware Telco Cloud Service Assurance deployment.
- Refer VMware Telco Cloud Service Assurance Domain Managers Performance Benchmarking and Sizing Guidelines document for planning IP, SAM, and ESM deployment.

Note: The following notes apply to demo and HA based footprints:
- The demo footprint is for non-production deployment without HA capabilities and cannot be upgraded and incrementally scaled. Also, it does not support the backup and restore feature.
- The table shows the VMware Tanzu Kubernetes Grid management cluster sizing for deployments when a dedicated VMware Tanzu Kubernetes Grid management cluster is used for the VMware Tanzu Kubernetes Grid workload cluster in VMware Telco Cloud Service Assurance. To size deployments when multiple workload clusters are managed by a single management cluster, see VMware Tanzu Kubernetes Grid documentation.
- For VMware Tanzu Kubernetes Grid management and workload cluster, it is recommended to enable vSphere HA for VMware cluster.
- By default in AKS, first three worker nodes can also be the control plane nodes. For the different footprints, the recommended AKS VM size template is Standard_D16s_v3.
- The default raw metrics retention interval is 1w and is configurable. If you decide to change the retention interval period, the persistent volume storage must change accordingly.
- For each of the deployment platforms, a container storage interface is required so that persistent volumes can be allocated from the underlying infrastructure. System requires a storage class provided by the infrastructure that can be used for deployment of stateful services. For the required storage class, see the section for the relevant deployment target.
