VMTurbo is highly scalable to an unlimited number of VMs. In order to achieve this scale VMTurbo uses an aggregation system after an environment surpasses 10,000 VMs.
In this architecture multiple VMTurbo instances are deployed. The worker instances each attach to a set of vCenters consisting of about 10,000 VMs. These can typically be segmented by geographical location. The individual instances are then rolled up with an aggregation instance that allows for a single pane view into the entire environment.
For more information on setting up an aggregation instance see Large-Scale Deployment: Primary Instances with Aggregate Instance and consult your VMTurbo engineer.
