Data center construction
Internet Data Center Internet Data Center, referred to as IDC data center, is a combination of traditional data center and Internet. In addition to the characteristics of traditional data center, such as data concentration and reliable host operation, it should also have access methods. Changes in the world, 7x24 service, fast response speed, etc.
IDC is a base for providing resource outsourcing services. It should have a very good computer room environment, security assurance, network bandwidth, the number of hosts and host performance, large storage data space, software environment, and excellent service performance. The design integrates multiple professional technologies such as architecture, structure, electrical, HVAC, water supply and drainage, fire protection, networking, and intelligence. It should have the characteristics of "good safety performance, reliability and uninterrupted".
It can provide professional server hosting, space leasing, network wholesale bandwidth and even ASP, EC and other services for enterprises and various websites. Simply understand, IDC is a hosting place for hosting enterprises, merchants or website server groups; it is the infrastructure on which various modes of e-commerce depend on the safe operation, and it also supports enterprises and their business alliances (its distributors, suppliers). , Customers, etc.) to implement a platform for value chain management. To put it vividly, IDC is a high-quality computer room, which has high requirements for all aspects in terms of its construction.
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. This high-performance network includes its-AN, WAN and Internet access.
IDC's network construction mainly includes:
(1) IDC-AN construction, including its-AN infrastructure,-AN level,-AN performance.
(2) The construction of IDC's WAN, that is, the construction of a wide area network that connects each branch of IDC to each other, etc.
(3) IDC user access system construction, that is, how to ensure that IDC users transmit data to IDC's data center in a safe and reliable manner, or maintain the user's own equipment stored in IDC, which requires IDC for users Provide corresponding access methods, such as dial-up access, dedicated line access and VPN.
(4) The construction of IDC and Internet interconnection.
(5) IDC's network management construction. Since IDC's network structure is quite large and complex, it is necessary to have a high-performance network management system to ensure its uninterrupted external service and high performance.
2. Server construction
IDC's server construction can be divided into multiple aspects, generally divided into basic service system servers and application service system servers, mainly including:
(1) Basic system server: This type of server is a prerequisite to ensure that IDC provides users with various services. This type of server includes DNS server, directory server, network management server, firewall server, various security servers, IDC system performance monitoring server, etc. Wait.
(2) Database server: It is the basis to ensure that IDC can provide users with various application services. IDC's database server must be able to support large-capacity access, multiple databases, etc.
(3) Data backup server: It is one of the contents of IDC providing customers with security services to ensure the safety and reliability of customer data. Because IDC has a wide variety of servers and a variety of databases, data backup must support multiple models, multiple data formats, etc., and have a large capacity.
(4) Application server: IDC provides users with related application services. Due to the expansion of IDC's business, the application server should have good scalability and support a large number of various application software.
(5) Server load balancing: This is one of the important methods for IDC to provide high-performance and high-reliability services. Server load balancing can be achieved by hardware equipment (such as network switching equipment) or software.
3. Construction of storage system
The storage system is one of the key construction contents of IDC. As an IDC, its storage system is quite large, especially in the current enterprise, the data capacity has increased from GB to TB. Such a large amount of data needs a A more secure and reliable storage system, because the number of accesses is also quite large, it also has high requirements on the efficiency of the storage system; and the storage system should have good scalability to meet the development needs of IDC
4. Construction of software system
The construction of the software system is an aspect where IDC needs a lot of investment. It is a means for IDC to develop external services on the basis of the previous network, server and storage system construction. IDC's software construction mainly includes:
(1) Web system: IDC is one of the content of Web-Hosting services. Web system software should support the establishment of Web system functions for multiple enterprises on one system.
(2) E-mail system: The e-mail system should support multiple e-mail protocols, such as SMTP, POP3, IMAP4, Web-Mai- and Voice-Mai-, etc., and the e-mail system should have good scalability.
(3) Database system: IDC should establish a database system of multiple manufacturers, such as Orac-e, Informix, SQL Server, SyBase and other manufacturers to meet the needs of different users.
(4) Security system: such as firewall software (except hardware firewall), anti-hacking, anti-virus software, etc. This is a prerequisite to ensure that IDC provides users with a secure server.
(5) Data backup software: support multiple backup devices, multiple manufacturers' machines, multiple databases, etc.
(6) Application development system: IDC shall provide corresponding development system platform and corresponding development tools to meet the needs of users or IDC to develop corresponding applications.
5. IDC's own service system construction
IDC relies on its high-quality services to occupy the market and win customers. In order to achieve high-quality and efficient services, IDC must also invest a lot in the construction of its own server system. IDC's own service system mainly includes:
(1) Customer relationship management system (CRM): CRM is a basic service system for IDC to establish a good relationship with customers. It provides IDC with the development of users and new needs of users.
(2) Billing system: The billing system is the guarantee of IDC's revenue.
(3) Network and server management system: IDC has a huge network and server system. To manage these systems, you must have a powerful network, server and application management system, which can ensure the quality of IDC's external service.
(4) IDC's internal management system: to ensure that all departments within IDC can coordinate their work and complete high-quality services.
6. Computer room site construction
The construction of the computer room site is the largest part of IDC's initial construction investment. Because IDC users may store their important data and applications in the IDC computer room, the requirements for the IDC computer room environment are very high. IDC's computer room site construction is mainly in the following aspects:
(1) Computer room decoration: The computer room decoration mainly considers suspended ceilings, partition walls, doors and windows, walls and raised floors.
(2) Power supply system: The power supply system is one of the key points of IDC's site construction. Since a large number of IDC equipment requires a great deal of power, the reliability and scalability of the power supply system are extremely important. The power supply system construction mainly includes: power supply, UPS construction (n+1), power distribution cabinets, wires, sockets, lighting systems, grounding systems, lightning protection and self-generation systems, etc.
(3) Air conditioning system: the temperature, ventilation method and air environment of the computer room.
(4) Security system: access control system, fire fighting system and monitoring system.
(5) Wiring 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.
