A single physical server providing all three cloud functions (controller, worker and storage).
- All-in-one Duplex (up to 50 worker nodes)
-
Two HA-protected physical servers, both running all three cloud functions (controller, worker and storage), optionally with up to 50 worker nodes added to the cluster.
- Standard with Storage Cluster on Controller Nodes
-
A two node HA controller + storage node cluster, managing up to 200 worker nodes.
- Standard with Storage Cluster on dedicated Storage Nodes
