I believe many of my friends in the choice of the time IDC hosting server room, in addition to considering location, price factors, the relationship between the room and the room is the quality of the network.
How to judge a room hardware and network quality? Generally more formal room operators, agents in their official website will give some key information that can be judged according to these presentations.For example:
1. Through 6.0G direct access to multi-core optical fiber backbone network ChinaNET
2. Henan, Shandong, Beijing Telecom / Netcom room is the core node in central China
3. Connectivity rate of 99.9%
4. National Class room Super Data Port
5.24 hours constant power control
6. On request exclusive bandwidth to support 2M-1000M
7. Equipped with first-class fire protection, security, air conditioning, construction and other environmental
8. Three power environmental protection and ensure the normal operation of the server
9. The first time under the emergency response and support
Analysis:
As a direct backbone access to ChinaNET This condition is in line with all the regular rooms, the key is that it uses much bandwidth access, above the engine room is 6.0G, be large or small? Should be said that a medium, the basic mediumlevel.10G or more generally the majority of the focus of the telecommunications room at the provincial level, such as Dongguan, Guangdong Telecom telecommunications room is three core room, which access the backbone network bandwidth is 20G, and Jiangmen, Guangdong Telecom, the only 2.5G room access ChinaNET,As most of the non-self-built room telecom operators, many of them are double or even multi-line telecommunications access Netcom, the total bandwidth of its export base in the 5G the following, but large individual carriers of cooperation with the Telecom and China Netcom backbone bandwidth can exceed the roomnumber, for example, Internet century.
The super-national Category A data port that a room is the room that hardware and environmental conditions, this short sentence can be seen how the infrastructure and facilities room how to do? Is the case, the state has a very detailed Class roomstandards, including disaster prevention, power, temperature control, access control and other aspects, several criteria must be forced to reach, if the operator shows the state Class-room, this room will have the following facilities in the general conditions for the Guangzhou telecommunications roomExample:
1. High-quality room space and environmental protection
Data center room can be used to provide 3,000 square meters room area, room for earthquake resistance level for the overall level 8.Room with load-bearing structure design, floor loading limit of 800Kg / sq m, available for users to put some special type of equipment.
System to provide just the data center room standard rack (rack width of 19 inches, height 2.6 or 2.4 meters).The engine room engine room staff for a day of health, the data center room air conditioners by more than one side to send and duct using a combination of air transport, so that a balanced distribution of indoor temperature and humidity as much as possible in order to maintain constant temperature and humidity environment.Room temperature: 18 to 28 degrees Celsius, relative humidity: 30% to 70%.
2. Reliable power protection
Data center room with a class of electricity supply, stable and reliable from two independent power their way into power lines, two with 10kv electricity lines, Internet-based backup.To protect the user assigned to the continuous supply of electricity, data center power room to install a smart UPS systems and sufficient capacity of the battery, you can ensure continued supply.In addition, the data center is also equipped with dual backup diesel generator as a backup.
3. Advanced security, fire protection
Data center 24 hours a day building the professional security personnel, the user is required to register or enter the building access card holders.In order to ensure the security of user managed device, data center, equipped with a U.S. company's closed-circuit television monitoring system AV, TV wall monitoring system is designed seat 24 hours a day, the data center room to install the German Siemens company's non-contact IC card electronic access control systems,the use of advanced database management.
Data center room, fire-resistant architecture and decoration materials, fire capable of meeting carrier-grade standards.The building has multiple emergency access, room and corridor smoke detectors installed fire fighting system temperature, fire alarm detection head, the event automatically when the fire alarm, and start the automatic gas fire extinguisher.
Data Center building has 24-hour professional security personnel on duty, when the user enters the building access card to be registered or held.In order to ensure the security of user managed device, data center, equipped with a U.S. company's closed-circuit television monitoring system AV, TV wall monitoring system is designed seat 24 hours a day, the data center room to install the German Siemens company's non-contact IC card electronic access control systems,the use of advanced database management.
Data center room, fire-resistant architecture and decoration materials, fire capable of meeting carrier-grade standards.The building has multiple emergency access, room and corridor smoke detectors installed fire fighting system temperature, fire alarm detection head, the event automatically when the fire alarm, and start the automatic gas fire extinguisher.
4. High-speed and stable network security
Data center through two high-speed Fibre Channel Gigabit Ethernet (GE) directly interconnect ChinaNet backbone nodes, Guangdong Province, to effectively protect the network stability and high speed.The importance of the data center network equipment using double-point backup, to avoid single point of failure, and enhance network reliability.
The main point is that the parameters of the hardware facilities, in fact, a room there is a very important condition is that it's network environment, we know, IDC engine room of the network is the world's busiest network environment, generally excellent rooms are used Ciscocore routers and switches, back a grade on the use of Huawei's network equipment, or to use D-LINK device, then the room probably has a good network conditions, what? We might compare to a good room for the multi-lineExample:
1. Bandwidth resources:
Commercial enterprises in China have a total of 10G of bandwidth online export resources, and China Netcom, China Telecom, China Railcom, China Unicom, Education Network, Great Wall Broadband, which are on the other fiber.And a backup fiber link, Implementation and INTERNET export redundancy.According to the user's needs we can expand the largest single cause 2.5G capacity fiber optic lines to the user where they are needed.Users can access line for small and medium resources, including ISDN, DDN, frame relay lines, while also providing 2M or more data transmission lines, optical fiber links.
2. Reliable, redundant network structure:
Room with a hierarchical network architecture is divided into the core layer, distribution layer and access layer, and a network system with full redundancy to ensure a highly reliable network systems.CISCO in the core layer using high-performance backbone routing equipment and Huawei MAN backbone routing equipment.Three-tier distribution layer using CISCO switches and redundant Gigabit fiber connections core layer; server uses CISCO access layer switches, Layer 2 switches.We use Cisco 75 Series router as the user's access server line to ensure that the user's exclusive bandwidth.Used in all major network equipment, dual power, dual-engine configuration, the complete elimination of single points of failure, to ensure network reliability of 99.999%.
3. Comprehensive network management system:
A comprehensive enterprise network management software, network equipment providers online room including routers, LAN switches for comprehensive management, can be configuration management, fault management, performance analysis, network monitoring, port traffic analysis, business statistics and business analysis.Network management center personnel with real-time monitoring network.Host monitoring software with a professional application services on the host real-time monitoring, a rich choice of services and improve the alarm to run your server security escort.
Of course, our rooms as a multi-line multi-line only because of the current two-lane more popular, not to say that there must be two-or multi-line access can be called great room, after all, or most of the large room, Telecom and Netcom, who is the competition between the two sides can not cooperate with each other, engage in two-lane, we judge the way a room key or the network environment to see it with the backbone bandwidth, the use of network equipment and network design.
Summary:
If we select the hosting room in time if there is doubt, may wish to take the information in the room above the engine room were compared with the other key, of course, the specific server network conditions also need to know the week before the trial.
Finally, the reader must remind you, as the rapid development of the Internet industry in recent years, the domestic load a lot of focus on the engine room have been close to saturation, especially in the engine room of network bandwidth resources have been tight, so operators will share on the user's bandwidth 100Mmore stringent restrictions, the specific number depending on the degree of saturation of each room is concerned, serious limitations in the 1 ~ 2M, and therefore such conditions and the room although the total bandwidth of the hardware parameters such indicators are very good-looking, into custody after the fact will find the speednot how good, especially when access to large number of non-core nodes rather than the total bandwidth is not the ordinary urban room effect.
Therefore, we tell you how to study room-level room parameters and do not represent the high standard room certainly is the best hosting choice, we actually might pay more attention to our new room on the country reports, the beginning of the new bandwidth resource roomare relatively abundant, but generally there will not be the same cabinet how many other servers, network devices and will not compete for bandwidth, but results were better.
