IDC translates literally is the data center, it is the first for enterprises, media, website supply large-scale, high quality, safe and reliable Internet services, the first includes: server hosting, website space rental, bandwidth wholesale and other businesses. With many idc service providers now, so that many enterprises, government units, educational institutions and other units do not have to build their own room, also do not need to hire specialized technical personnel to protect the management, so that can save a large part of the cost.
From the perspective of idc career development history, in the 1960s, data backup during the mainframe era can be said to be the embryonic form of IDC. With the rapid development of the Internet, then into the network era, companies and individuals from all walks of life are beginning to establish a complex website, website is needed to operate on the service, and the server operation of the surrounding environment is very high requirements, and also need specialized technical personnel protection, which promotes many enterprises need a good room and data center to place the website, The idc data center was born.
With IDC data center, enterprises can give all the business related to website hosting services to IDC network service providers to do, they can put their energy and time on product development and operation, more can promote the progress and development of enterprises.
IDC data centers have two obvious characteristics, namely the location in the network and the total network bandwidth capacity. The two constitute part of the network base resources, which are the same as the backbone network and the access network. IDC provides a high-end data transmission access service

6. Redundancy
Redundancy refers to the repeated configuration of some system components. When some system components fail, the redundant components step in and take over the work of the faulty components, thereby reducing the system failure time.
7. N- Basic Requirement (Base Requirement)
The system meets basic requirements without redundancy.
8. N+X Redundancy
In addition to meeting the basic requirements, X units, X modules, X paths, or X systems are added to the system. The failure or maintenance of any X units, modules, or paths will not cause an interruption of system operation (X = 1 ~ N).
9. Fault Tolerant
Fault-tolerant systems are systems with two or more sets of the same configuration. At least two sets of systems are working at the same time. Each set of systems is of (N+M, M = 0 ~ N) structure. The site equipment configured with fault-tolerant system can withstand at least one serious sudden equipment failure or human error without affecting the operation of the system.
10. RelativeHumidity
Relative humidity φ represents the ratio of partial pressure of water vapor in the air Ps to partial pressure of saturated water vapor Pb at the same temperature, that is, φ = (Ps /Pb) ×100%

19. Sensible HeatRatio
The ratio of sensible heat cooling capacity to total cooling capacity expressed as a decimal not greater than 1
20. Indoor DischargeAir-Flow
Air conditioner Ventilation doors and exhaust doors (if any) used for indoor and outdoor air exchange are completely closed, and under rated refrigeration operating conditions, air volume into a closed space, room or area per unit time, the unit is m3/h.
21. Cooling-Air Ratio
Under the specified cooling capacity test conditions, the ratio of the total cooling capacity of the air conditioner to the air supply capacity per hour, the unit is W/ (m3/h).
22, external static pressure
The static pressure difference between the fan outlet and the return air outlet of the unit is Pa.
23. Air-ConditioningUnit Dedicated Used in Telecommunication Equipment Room.
The special air conditioner in the machine room is an air handling device with high reliability, high sensible heat ratio, and intelligent control functions such as automatic adjustment of air conditioning parameters, parameter detection, fault alarm display and power outage self-starting. Generally, the air supply volume is large, the air treatment enthalpy difference is small, the sensible heat ratio is large, suitable for data center room
24. PowerUsageEffectiveness (PUE)
PUE = Total Facility Power (Total Energy consumption of data center)/ITEquipment Power (total energy consumption of IT equipment)
25. HotAisle/Cold Aisle
Hot aisle/Cold aisle refers to the layout design of server cabinets and other computing devices in the data center. For forward air and rear air exhaust cabinets, the two adjacent rows of cabinets face each other back to back. The air inlet aisle of the two rows forms a cold aisle, and the air outlet aisle forms a hot aisle. Hot channel Cold channel construction is designed to save energy and reduce cooling costs by managing airflow
