Climatic Environment

The elements of the Bull DPS 9000/7xx two-cabinet computers which are capable of being extended to include up to seven IOSS cabinets, and their peripherals, use their internal fans to take the air they need for cooling from the environment of the room and expel it back into the room. The heat dissipation of the various machines is expressed in kW.

The air conditioning is therefore limited to the environment of the computing room and there should be no need to make specific adaptations to deliver the air under and/or into the computer.

The "data processing" environment complies with standard NF ISO 7730 dated December 1986, in other words the climatic environment is monitored, in terms of temperature (°C) and hygrometry (% RH = Relative Humidity).

The use of computer hardware in a climatic environment in excess of, or bordering, the extreme limits shortens the lifetime of the electronic components. This can adversely affect the dependability of the hardware.
