What is an IDC data center?

Internet Data Center Internet data center, referred to as IDC data center, is the combination of traditional data center and Internet. In addition to the characteristics of traditional data center, such as data centralization, reliable operation of host, etc., it should also have the change of access mode, 7x24 service, fast response and so on.

IDC is a base that provides resource outsourcing services. It should have very good computer room environment, security guarantee, network bandwidth, number and performance of hosts, large storage data space, software environment and excellent service performance. The design integrates many professional technologies, such as architecture, structure, electricity, heating, ventilation and air conditioning, water supply and drainage, fire protection, network, intelligence, etc., and should have the characteristics of "good safety performance, reliable and uninterrupted".

It can provide professional server hosting, space rental, network wholesale bandwidth and even ASP, EC and other services for enterprises and all kinds of websites. To put it simply, IDC is a place for hosting (Hosting) enterprises, merchants or web server farms; it is the infrastructure for the safe operation of various modes of e-commerce, and it is also a platform to support enterprises and their business alliances (their distributors, suppliers, customers, etc.) to implement value chain management. Figuratively speaking, IDC is a high-quality computer room, in its construction, there are high requirements for all aspects.

The construction of IDC is mainly in the following aspects:

1. Network construction

IDC mainly relies on its high-performance network to provide services to its customers, including its-AN, WAN and access to Internet.

The network construction of IDC mainly includes:

(1) the construction of IDC-AN, including its-AN infrastructure,-AN level,-AN performance.

(2) the construction of WAN of IDC, that is, the construction of interconnected wide area network among the branches of IDC, etc.

(3) the construction of IDC user access system, that is, how to ensure that IDC users transmit data to the data center of IDC in a safe and reliable way, or maintain their own equipment stored in IDC, which requires IDC to provide users with corresponding access methods, such as dial-up access, dedicated line access and *.

(4) the construction of interconnection between IDC and Internet.

(5) the network management construction of IDC, because the network structure of IDC is quite large and complex, in order to ensure its network uninterrupted external service and high performance, it is necessary to have a high performance network management system.

2. Server construction

The server construction of IDC can be divided into many aspects, which are generally divided into basic service system server and application service system server.

(1) basic system server: this kind of server is the premise of ensuring that IDC provides various services for users. This kind of server includes DNS server, directory server, network management server, firewall server, all kinds of security server, IDC system performance monitoring server and so on.

(2) Database server: it is the basis of ensuring that IDC can provide various application services for users. The database server of IDC must be able to support large-capacity access, multiple databases and so on.

(3) data backup server: it is one of the contents of IDC to provide security services for customers to ensure the security and reliability of customers' data. Due to the wide variety of servers and databases in IDC, data backup should support multiple models, multiple data formats and so on, and have a large capacity.

(4) Application server: it is the server that IDC provides related application services for users. Due to the business expansion of IDC, the application server should have good scalability and support a large number of all kinds of application software.

(5) load balancing of servers: this is one of the important methods for IDC to provide high performance and high reliability services. Load balancing of servers can be realized by hardware devices (such as network switching equipment) or software.

3. The construction of storage system

Storage system is one of the key construction contents of IDC, as an IDC, its storage system is quite huge, especially in today's enterprises, the capacity of data increases from GB level to TB level. Such a large data needs a more secure and reliable storage system. Because the number of visits is also quite large, there are also high requirements for the efficiency of the storage system. And the storage system should have good expansibility to meet the needs of the development of IDC.

4. the construction of software system.

The construction of software system is an aspect that IDC needs a lot of investment, and it is a means for IDC to carry out external services on the basis of the construction of network, server and storage system. The main functions of IDC in software construction are as follows:

(1) Web system: IDC develops one of the Web-Hosting service contents. Web system software should support Web system functions that can be established on one system to serve multiple enterprises.

(2) E-mail system: the e-mail system should support a variety of e-mail protocols, such as SMTP, POP3, IMAP4, Web-Mai- and Voice-Mai-, etc., and the e-mail system should have good expansibility.

(3) Database system: IDC should establish multi-manufacturer database system, such as Orac- e, Informix, SQL Server, SyBase and so on, to meet the needs of different users.

(4) Security system: such as firewall software (except hardware firewall), anti-virus software, etc. This is a prerequisite to ensure that IDC provides users with a secure server.

(5) data backup software: supports multiple backup devices, machines of multiple manufacturers, multiple databases and so on.

(6) Application development system: IDC should provide corresponding development system platform and corresponding development tools to meet the needs of users or IDC to develop corresponding applications.

5. Construction of IDC's own service system.

IDC relies on its high-quality service to occupy the market and win customers. In order to achieve high-quality and efficient service, IDC must also have a lot of investment in the construction of its own server system. IDC's own service system mainly includes:

(1) customer relationship Management system (CRM): CRM is the basic service system for IDC to establish a good relationship with customers. It provides IDC with the development trends and new needs of users.

(2) Billing system: billing system is the guarantee of IDC income.

(3) Network and server management system: IDC has huge network and server systems. In order to manage these systems well, there must be a powerful network, server and application management system, which can ensure the quality of service of IDC.

(4) the internal management system of IDC: to ensure that all departments within IDC can coordinate their work and complete high-quality service.

6. Construction of computer room site

The construction of computer room site is the largest part of the pre-construction investment of IDC. Because the users of IDC may store their important data and applications in the computer room of IDC, the requirement for the site environment of IDC computer room is very high. The construction of IDC computer room site is mainly in the following aspects:

(1) computer room decoration: computer room decoration mainly considers suspended ceilings, partition walls, doors and windows, walls and movable floors.

(2) Power supply system: the power supply system is one of the key points of IDC site construction. Because a large number of equipment of IDC need great power, so the reliability construction and expansibility of power supply system are extremely important. The construction of power supply system mainly includes: power supply power, UPS construction (Niss1), distribution cabinet, wire, socket, lighting system, grounding system, lightning protection and spontaneous charging system and so on.

(3) Air conditioning system: the temperature, ventilation mode and air environment of the computer room.

(4) Safety system: access control system, fire control system and monitoring system.

(5) cabling system: the computer room should have a complete integrated wiring system, which includes data wiring, voice wiring and terminal wiring.

(6) Communication system: including data line bandwidth, number of voice lines, etc.

Take the DCIM management system designed by Zhi Jane Rubik's Cube for the data center as an example, which integrates the most important critical infrastructure of the data center and IT equipment on the same platform. Through IPMI/Telnet/SSH/ control files and other ways to achieve remote access and complete control, can quickly and comprehensively integrate and analyze data center energy, power system, refrigeration system, environment, security, assets and server monitoring and other information, can be described as "the best guardian of the data center".
