With the expansion of scientific research technology in the IDC field, the computer room can be said to be favored, and the latest technology has finally been adopted by enterprises.
Single line machine rooms are mostly used in the early stage. Later, according to specific needs, the second and third line computer rooms began to be popular. For example, in the micro network, the second-line computer room and the third line computer room are now very mature, and the number of users has reached tens of thousands. What's the difference between a single line computer room and a double line computer room?
Third line machine room
Multi line computer rooms refer to the computer rooms owned by telecommunications, China Unicom and mobile lines. Some computer rooms even include education networks, science and technology networks and international export lines to meet some special purposes. Multi line computer rooms have solved the problem of interconnection between the north and the south, but customers from both the north and the south have visited quickly. Of course, the cost will be higher. This kind of computer room is suitable for customers with wide coverage. Most of the computer rooms in Beijing are multi line computer rooms, such as Zhaowei computer room, Digital North computer room, East Four Unicom computer room, Shangdi Telecom computer room, etc. They are all multi line computer rooms accessed by at least four lines, with good network stability and security.
Double line machine room
The double wire machine room is due to the interconnection of two domestic network telecommunications and Netcom. Therefore, the speed of telecom users visiting Netcom websites or Netcom users visiting telecom websites is very slow. In order to solve this problem, there are double line computer rooms, double line servers, double line server hosting and double line server leasing services. The two-wire machine room is actually a machine room with two telecommunications/Netcom channels. Through the router setting in the two-wire machine room and BGP automatic routing analysis, telecom users can access telecom lines, Netcom users can access Netcom lines, and Netcom can access quickly.
The double line machine room mainly consists of the following components
(1) Main engine room. It includes network switch, server cluster, storage, data input/output, cabling, communication area and network monitoring terminal.
(2) Foundation workshop. Including office, buffer room, corridor, locker room, etc.
(3) Class I auxiliary room. It includes maintenance room, instrument room, spare parts room, magnetic media storage room and reference room.
(4) Secondary auxiliary room. Including low-voltage power distribution, uninterruptible power supply room, battery room, precision air conditioning system room, gas fire extinguishing equipment room, etc.
(5) Grade III auxiliary room. Including storage room, common rest room, toilet, etc.
The network coverage has been very wide, with a large number of customers all over the country. This kind of computer room can be selected, but you must pay attention to selecting regular computer rooms and IDC service providers as far as possible, and go to the office and computer room for inspection.
