A data processing center (DPC) or data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems.
Hyperconvergent Infrastructure (HCI) combines computing, storage and network.
HVAC
Heat, ventilation and air conditioned (HVAC)

Air-based
Direct Expansion
Direct Expansion (DX) is a type of air-conditioning system that removes heat from a space through evaporation and condensation of a refrigerant. The refrigerant absorbs the heat in the air, such as the heat generated by IT equipment in a network closet or other IT space, and then ultimately rejects the heat outdoors.
It is simple and economical, suitable for a small data center.
Condensation in a cooling tower
Condensation in a cooling tower uses a cooling tower to condense and remove heat from a system, often employed in industrial and HVAC applications.
They are more efficient but require more investment.
Centralized air management systems
Centralized air management systems controls and distributes air throughout a facility from a central unit to optimize cooling efficiency.
Low-pressure air delivery
Low-pressure air delivery (in Spanish, entrega de aire a baja presión) supplies cooled air at a lower pressure to reduce energy consumption and improve airflow control.
Aisle containment
Aisle containment (in Spanish, cerramiento de pasillo) encloses hot or cold aisles in data centers or server rooms to improve cooling efficiency and prevent air mixing.
Hot/cold aisle techniques
Hot/cold aisle techniques in arranges server racks in alternating hot and cold aisles to enhance airflow management and cooling effectiveness.
Free-cooling
Free-cooling is utilizes cool ambient air to lower the temperature of a system, reducing reliance on mechanical cooling and improving energy efficiency.
Rack-enclosure
Rack-enclosure (in Spanish, cerramiento de bastidores) A containment system around IT equipment racks to optimize airflow, enhance cooling efficiency, and prevent hot and cold air mixing.
It may be used in an HPC with special needs.
Water-based
There are water-based systems.
Data Center Certifications
ANSI TIA-942 is a certification issued by ANSI. You can find more information about this certification on this link.
Data Center Security
Uninterruptible Power System (UPS).
Generator.
Power distribution unit (PDU) is used to get power to server and systems and to control and monitor it.
Power Usage Effectiveness (PUE) is the energy efficiency of a data center.
