How to choose Reliable Colocation Server

There are no industry standards to maintain a placement service, but it can help to develop key sectors: electricity, refrigerators, Internet access and service. Good reliability offered by the inclusion of redundancy, maintenance and service, which means that over the availability of networks and equipment for the duration of life. Ask questions, prepare answers to the research, and finding the mechanism that meets the needs of its customers. 

Power 
A placement service is a benefit of reservations, not only for producers but also the universal power supply (UPS) and the transition or transfer of power. 

UPS start the server for the power to regulate electricity. Whatever the quality, the UPS does not routinely have several UPS facilities have sufficient capacity to handle all the load on the server, if they are not. Transfer or power button to turn generators.
circuit breakers are more reliable as a transfer, but it is important that a backup system or power, so that can be transferred to the device failure.  
Given that the main source, the generator must be large enough to accommodate 1.5 times the load of the entire building. If there are more producers, placement services should be able to load between the producers, because failure could disable all the alternators.
Cooling
It does not take into consideration the availability and maintenance of equipment is cooling. All the servers are still hot to operate at room temperature between 72 ° C and 76 ° F. your air conditioning (CRAC) units, refrigerators, furniture design and to ensure that all servers receive the proper cooling. High-end placement of plants regularly to maintain refrigeration systems and control temperature, humidity and energy consumption for optimal performance. 

Refrigerators tube liquid cooled CRAC units. It is redundant and cooling pumps, which are automatically in the event of default, so the CRAC units to continue operating.
CRAC units are large (20 to 30 tons), a specialist in air conditioning, cold air blowing constantly. The minimum number of CRAC units to cool an investment, or 030 per square meter tons. If there are four units of 30 tons and the facility is 4000 square meters, or 030 tons per square foot (120 ÷ 4000 tons of square feet).
Design of the plant must have designated series of hot and cold. Server fans blowing hot air at the rear of the server set hot, the CRAC units blow cold air from the cold front in the file server. Track fan should go on one side of the room to draw hot air from the server, and the cold air in the fan is blowing the top of the server rack. Soil designs blow cold air with enough pressure from the air at the top of the grid.
Internet Connection 
There are two main types of Internet connection. 

Level 1 provider networks that are reliable and fast, but often with low latency and high performance outside the network.
Level 2 purchase access to multiple Tier 1 networks, so that the speed and reliability for better performance and latency of a larger network. Some 2-level supply routing of traffic between the networks efficiently, the promotion of network performance by 50% and the creation of a network of self-healing.
service
The quality of investment services offer additional services, including: 

service 24 hours on the line, in addition to the art scene of an emergency. 
change the backup tapes and store in a fire.
car accident with monitors, keyboards and other instruments, a computer crashes.
structural design earthquakes, storms and floods.
Visit service offering, the notes and ask questions about their systems, backup and maintenance, and find the plant with the service, access, quality and attention to your company reliable, reliable network.
