Cooling Feed
A cooling feed represents a coolant loop delivered from a cooling source to a particular rack or coolant distribution unit (CDU). The cooling intakes a feed supplies are derived from the devices installed in the rack it serves, rather than referenced explicitly.
A single feed represents the entire loop, covering both the supply (cold) and return (warm) paths.
!!! tip
In-rack cooling equipment — coolant distribution units (CDUs), manifolds, and rear-door heat exchangers (RDHx) — is modeled as an ordinary (typically zero-U) [device](./device.md) installed in the rack. The device's make and model come from its [device type](./devicetype.md), and a [cooling intake](./coolingintake.md) component connects it to cooling. The feed serving such a device is derived from its rack.
Fields
Cooling Source
The cooling source which supplies this feed.
Rack
The rack which this feed serves (optional).
Name
The feed's name or identifier. Must be unique to the assigned cooling source.
Status
The feed's operational status.
!!! tip
Additional statuses may be defined by setting `CoolingFeed.status` under the [`FIELD_CHOICES`](../../configuration/data-validation.md#field_choices) configuration parameter.
Cooling Capacity
The heat-removal capacity of the feed, in kilowatts (kW).
Maximum Flow
The maximum rate of coolant flow supported by the feed, expressed as a numeric value with a selectable unit (liters per minute, cubic meters per hour, or gallons per minute). Must be a positive, non-zero value in the selected unit, or left blank.
