The hierarchical mesh configuration shown in Hierarchical Mesh Service Assurance configuration is used to support the largest, most complex deployments that require multiple Presentation Global Managers and multiple Aggregation Global Managers.
As with the other hierarchical configurations, it is recommended that each additional Aggregation Global Manager should support up to 10 underlying domains and each additional Presentation Global Manager should support up to 100 simultaneously connected clients.
Deploying the hierarchical mesh configuration requires the aid of VMware Smart Assurance Professional Services.
