This solution encompasses a fully functional PowerFlex system which is engineered for complete fault redundancy and ability to scale out across compute and storage dimensions. At a minimum, three controller nodes for running the management stack and four PowerFlex hyperconverged nodes running VMware ESXi to deploy GKE on-prem. For information about the Google Anthos supported ESXi version, see Google Anthos Version history.
Also, at least one outbound connection to Google Cloud APIs (*.googleapis.com) is required to complete the Anthos cluster registration and deployment processes.
Anthos can manage multiple Anthos clusters across geographically dispersed PowerFlex systems through a single pane of glass with GCP console.
