Rack-Based Cooling Solution
The Rack-Based Cooling approach takes the concept
of Row-Based Cooling one step further and places the air conditioner
and humidifier appliances in close proximity to the IT devices to be
cooled. By being in close proximity and, therefore, dedicated to a
single rack of equipment, the rack-oriented airflow paths are even
shorter and exactly defined, so that airflow are totally immune to
any installation variation or room constraints. All of the rated
capacity of the CRAC can be utilized and the highest power density
(up to 50 kW per rack) can be achieved.
Similar to row cooling, the rack-oriented
architecture has other unique characteristics in addition to
allowing extremely dense rack designs. The reduction in the airflow
path length reduces the CRAC fan power required which increases
efficiencies.
A rack-oriented design allows cooling capacity and
redundancy to be targeted to the actual needs of a specific rack so
a mixture of rack and blade server cabinets is ok within a single
row. The biggest problem with this approach is that it requires a
large number of air conditioner devices and associated piping when
compared to other approaches. It also is typically more expensive to
deploy the rack-specific hardware.
Rack-based cooling designs typically use chilled
water or refrigerant as the cooling medium. However, the majority of
product designs don’t actually deliver the liquid into the cabinet
but into a separate enclosure or cooling device integrated into the
rack design. The equipment itself is still air cooled.

As with row-oriented architectures, there are a number of side benefits other than cooling performance for rack-based designs:
- The reduction in the airflow path length reduces the CRAC fan power required, increasing efficiency.
- A rack-oriented design allows cooling capacity and redundancy to be targeted to specific racks.
- Rack-based cooling allows a data center, computer room, or server room to be implemented without a
raised floor.
- In-Rack cooling allows for varied room designs and constraints. For example,
load-bearing supports can be managed at the row level rather than trying to handle at the room level.
