Number of Sites and VNFs Supported in Contrail Service Orchestration
Cloud-hosted CSO 5.0 supports up to 6000 sites and 2 VNFs for a Hybrid WAN deployment and up to 6000 sites for a Hub and Spoke SD-WAN deployment.
An on-premise CSO deployment supports three environment types: small, medium, and large. The small environment does not include any high availability features for the CSO platform itself, while medium and large deployments do support HA for the CSO platform.Table 1 shows the number of sites and VNFs supported for each environment.

Each environment has different requirements for:
The number and specification of node servers and servers. See Minimum Requirements for Servers and VMs
The number and specification of virtual machines (VMs). Provisioning VMs on Contrail Service Orchestration Nodes or Servers
For a cloud-hosted CSO deployment all of the node server and VM details are handled by Juniper Networks. The links above point to CSO 4.1 on-premise installation information.
