Number of Secure Access Sites
Secure Access Sites allow you to divide up your Secure Access deployments. Each Secure Access Site is an isolated deployment in which the components will only communicate with other components in the same Secure Access Site. This is primarily useful in environments containing locations with high-latency connections or in environments with locations whose internal IP space overlaps.
Secure Access requires that you deploy at least two Virtual Appliances for a Site. This ensures high availability of the Virtual Appliances and the option to receive updates without downtime.
