On the data center needs and cable fire safety standards
Focus: The new law implemented Corporate social responsibility, most major league of Fire
HC Fire Network UAV data center room and system administrators into the work area (some areas), in which the administrator of the workspace environment with essentially the same as commercial buildings, fire safety requirements so it can refer to GB50311-2000 standard, the provisions of the cable fire , namely: the people's escape, the fire did not spread as the goal, using Flame Retardant , Low smoke and toxicity of the cable material. Typical series of such cable in the United States CMx cable and flame retardant low smoke zero halogen cables and Europe LSOH cable.
Room for the UAV, the situation is somewhat different. First of all, there is no staff room; Second, in the engine room has a large amount of information equipment; third, the flame may spread along the cable to the UAV UAV outside the room or spread to the room. In order to solve these three problems, you can use CMP levels of integrated wiring cable, to use their cable to up to 500 in temperature, is still able to maintain for 20 minutes without damage to the superior characteristics of an emergency backup for the information some time left .
1, two fire wire Standard Series
IEC60331 series are fire-resistant cable series, which requires cable still has qualified in the flame transmission capacity, the indicators are: at 750 to continue to work 30 to 90 minutes (divided into 30 minutes, 60 minutes, 90 minutes three grades). It features: on the spot when the temperature reaches 750 , cable still 30 minutes to 90 minutes to work, so give Fire Alarm And emergency radio offers the possibility of directing the evacuation, but also to the normal shutdown and emergency computer data backup provides a time;
IEC60332 series are flame-retardant cable series, which requires cable does not spread in the flame (flame retardant), less smoke (smoke), non-toxic (non-toxic halogen element exists), that is, to prevent the fire spread along the cable, and allows the staff stuck in the scene with the possibility of escape.
Corresponding to the two international standards, in 2001 formed the Ministry of Public Security Standards GA306.2 and GA306.1, in 2007, but also of the two standards upgraded.
2, UAV room in the data center needs of the fire wire
No work in the data center (UAV room) as well, with Fire Alarm systems and alarm and light, in the UAV temporary staff room in the event of fire can be the first time after the withdrawal of room, only the hosts, servers, storage equipment, and so remained in the engine room, not on their own escape.
In the face of this situation, in addition to ensure personal safety, whether to prevent the fire from spreading to the UAV room, fire room whether the UAV can guarantee the maximum extent within the information security device, it can protect the equipment connectors are not subject to corrosive gas corrosion, fire becomes a must to consider another problem.
For information systems, are the most valuable information, not the equipment. For information security, it launched a redundancy, backup, remote backup in various ways, No expense was spared to ensure that the information should be intact. For information within the data center, if able to ensure that equipment immediately after receiving the fire started Guilong data, and they all transferred to a safe place, then the normal shutdown of computer equipment, which will minimize the possibility of information loss .
Even off-site backup, there are still some interim summary of information needs. For example, in some of the district center, UPS will provide power for some computers so that data can be timely Gui Long.
However, this series of work is paid for with time, if the transfer cable can not at the scene to maintain normal transmission capacity, we can not talk Guilong data. If the power cable can not fire the ability to maintain power, it far from the normal shutdown of computer equipment.
