An Image Streamer appliance can serve all the compute modules in the logical enclosure (a ring containing HPE OneView and Image Streamer appliances) where it is placed.

Each logical enclosure using Image Streamer deployment has a separate Image Streamer appliance. The Image Streamer deployment server manages the group of all Image Streamer appliances present in the HPE Synergy hardware, managed by that HPE OneView instance.

When more than a pair of Image Streamer appliances serve an enclosure ring, then one of the appliances is designated as a primary appliance. The primary appliance runs the entire Image Streamer user interface, database, and all the resource managers. Whereas, the secondary appliance can only run a small subset of the resource manager. Both the primary and secondary appliances host the boot and run volumes for compute modules.
