Locating Open Rack v1 and v2

Open Rack v1-2 complete with facilities and IT systems: Chassis, power shelf and PSU, battery backup system, bus bar distribution along with server, storage, converged, GPU and networks, offers our community, for the first time, a means of standardising how we deliver and operate data centres. The complete nature of Open Rack enables datacentre operators to locate and re-locate (migrate) capacity as needed – on demand at a fraction of historical overheads. Open Rack v2 (pic below) is demonstrated with front and rear doors (optional).
