Data centers as physical locations of expensive computers and networking equipment are extremely sensitive to environmental influences. A temperature rise can cause overheating and even complete failure of servers. On the other hand, overcooling during "off-peak" leads to the waste of electricity and unnecessary expenses.
The incorrect humidity level can cause problems in both cases if it is too low or too high. When it is low, servers and other computer equipment are susceptible to electrostatic discharge which can cause damage to sensitive components. When it is high, water condensation can occur. This can lead to hardware corrosion and equipment failure.
Data centers are huge consumers of energy that must be operational at all times. Power outages or load shedding from the grid can cause serious damage to businesses. Automation is needed to keep a constant power supply and turn the backup generator when the main power source is off.
Moreover, server rooms are premises with a high degree of fire hazard due to possible short-circuiting of electrical components, electronic overheating, or subfloor wiring damage.
