Power (10%)
Challenges
Other (3%) Server demand (50%)
ASHRAE will extend the operational range (temperature and humidity) for server, switches and storage devices Free cooling will become more popular Increase of density will require higher cooling power per rack

Motivation Todays cooling solution in small datacenters Comfort cooling
Disadvantages / Limitations Split air conditioning units are usually used for conventional room cooling
Ceiling and wall cassettes are generally intended for air conditioning for humans, and are not suitable for IT cooling Compared with the LCP DX, the units have a low airflow, in order to avoid drafts (for humans) in the room being cooled. In most cases, this low volumetric airflow is insufficient for IT equipment

Motivation Todays cooling solution in small datacenters Comfort cooling
Consequences Lower airflow Humidification of the air Part of the energy is used for this More energy consumption Regulation based on return air instead of intake air Cooling of higher volume More energy consumption

Motivation Todays cooling solution in small datacenters Conventional room cooling with split cooling units Technical specifications of a wall cassette The typical intake side delta T of a server is 15 K At medium load in an IT room with, ex. 7 kW, this would correspond to a required air throughput of approx. 1,400 m³/h This is 2.31 times higher than the maximum specified volumetric airflow of the wall Cassette at the top (606 m³/h) LCP DX provides a maximum of 4,800 m³/h

Motivation Todays cooling solution in small datacenters Conventional room cooling with split cooling units
Consequences of an inadequate volumetric airflow for IT equipment: air short-circuit More air is being moved by the IT equipment than is provided by the wall cassette Consequence: hot air from the rear of the rack is drawn forwards and mixes with the cold air. This increases the intake air temperature to the IT equipment, resulting in a reduced service life or the premature failure of IT components
Advantages Concept made for IT cooling Higher adaptable airflow Better temperature distribution over the height of the rack Higher return temperature Adapted to be coupled with Rittal IT racks

LCP rack Increased efficiency – lower energy consumption Smaller volume to be cooled
Higher airflow and higher evaporation point
Lower energy consumption Up to 30%
Higher return temperature – perfect separation
Regulation on intake temperature instead of return air

The monitoring solution: CMC III Your IT rack perfectly monitored Modular monitoring system
The sensors send their data cyclic to the central Processing Unit For every measured value a limit can be defined measurements
If the defined limit is exceeded, an alarm is triggered Different ways of alarming are possible (e-mail, SMS, relay contact, SNMP-Trap) Optional: Automatic reaction is programmable (server shutdown, switching, etc.) Limitexceeding
