Guidelines for deploying Secure SD-WAN in the Engine/VPN role

There are some general deployment guidelines for Engines, Master Engines, and the SMC.

Table 1. Guidelines for deploying Secure SD-WAN in the Engine/VPN role
Component General Guidelines
Management Server Position on a central site where it is physically accessible to the administrators responsible for maintaining its operation.
Log Servers Place the Log Servers centrally and locally on sites as needed based on log data volume and administrative responsibilities.
Management Clients Management Clients can be used from any location that has network access to the Management Server and the Log Servers.
Management Server Position on a central site where it is physically accessible to the administrators responsible for maintaining its operation.
Engines Position Engines at each location so that all networks are covered.
Engines can be clustered. Functionally, the Engine Cluster is equal to a single high-performance Engine. Cluster deployment sets up a heartbeat link between the Engines. The heartbeat link allows the devices to:
  • Track each others’ operating status.
  • Agree on the division of work.
  • Exchange information on traffic.
Master Engines Position Master Engines where Virtual Engines are needed. For example, at a hosting location for MSSP services or between networks that require strict isolation. Master Engines can be clustered. A clustered Master Engine provides scalability and high availability. In a Master Engine Cluster, the Virtual Resource is active in one Master Engine at a time. Cluster deployment sets up a heartbeat link between the Engines. The heartbeat link allows the devices to:
  • Track each others’ operating status.
  • Agree on the division of work.
  • Exchange information on traffic.
