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

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
