Storage+Compute: Existing Scale Computing HC3 clusters can be expanded by adding additional nodes, which adds additional compute and storage resources to the shared pool.

Compute-only: N/A; A Scale Computing HC3 node always takes active part in the hypervisor (compute) cluster as well as the storage cluster.

Storage-only: A Scale Computing HC3 node can be configured as a storage-only node by setting a flag and has to be performed by Scale Computing engineering (end-user organizations cannot set the flag themselves).
