Expected Rack
Expected Rack identifies a Rack that is expected to be discovered at a Site. Infrastructure Providers can pre-register Expected Racks with an operator-supplied
rack identifier and a Rack Profile reference to help with Rack discovery and ingestion. Chassis identity and physical location information are conveyed via
well-known label keys (chassis.manufacturer, chassis.serial-number, chassis.model, location.region, location.datacenter, location.room, location.position).
