HVAC: technical principle of energy-saving air conditioners in data centers According to statistics, air conditioning consumes 20% of the total energy consumption in the communication room ~ 45%, and some may even exceed 60%. Therefore, to ensure the normal operation of communication equipment, energy-saving should first begin with the large energy-consuming user of air conditioners. Currently, most of the

MPO/MTP high-density optical fiber pre-connection system is mainly used in three fields: application of high-density environment in data centers, application of optical fiber to building, application of optical fiber to optical splitter, 40G, 100g sfp, connection applications of SFP + and other optical transceiver devices. This article focuses on why MPO/MTP high-density optical fiber pre-connection system

Cabling slot design in data centers In the data center, all devices are interconnected through optical fiber cables or cables. Therefore, when you enter the data center, you will see various cables connected to different devices. How to wiring so many cables is a learning. The quality of wiring not only affects the ap

Good grounding of metal pipes can reduce interference and improve the line fire protection level of the equipment room. At the same time, the metal cable trough is used as the routing material to make full use of the cable slot's good scalability and easily add the characteristics of cables. Generally, the cable slots are arranged around the devices. Currently, the parallel layout of cabinets and into racks is more and more common. Generally, a cable slot is arranged for each cabinet, or a cable

Green cloud computing has many benefits: lower costs, faster upgrades, and simpler O M. From the perspective of social interests, it reduces the environmental burden by reducing carbon emissions. "The energy use of data centers is an important consideration. Cloud solutions are more efficient than traditional systems ." Eric Woods of Pike Research said. This is because the carbon footprint of IT has recent

Cannot be overly obsessed with virtualized data centers At present, the industry's interest in data center and virtual environment automation is growing-automation frees administrators from daily hard work, IT professionals are allowed to focus on more strategic projects that can bring long-term practical benefits to the business. However, virtualization automat

modern cooling system HVAC systems are typically the second largest power consumption system in the data center, with data center Users Group Estimating 37% of the energy consumed in the datacenter. Air conditioning system can only achieve high efficiency when dealing with a small range, in the face of large-scale data center, most cooling system cooling task c

How to better monitor data centers Enterprises hope that before the problem arises, the intelligent analysis function can bring the enterprise's system monitoring to a new level. Now, IT is an important capability for the IT department to make proper planning of production capacity to maintain smooth operation. In addition to achieving IT and business goals, IT can help maintain the IT infrastructure of en

The reliability, delay and consistency of the distributed system are general problems, not limited to the database, and Cassandra provides a good solution to the problem.Cassandra claims to be able to achieve the efficient access to database access across data centers, and it is implemented in a way that gives users the tradeoff between latency, throughput, and consistency. Cassandra provides two levels of

Construction solution for local data centers with 150 nodes I. Local Data Center When I came into the company last year, there were only 20 people, and now it has grown to 100. At that time, the office was quite small and could accommodate up to 40 employees. By March, the company plans to move its office. In view of the office environment at that time, in fact,

Demand:The app uses the H5 page to make the display, and to get the corresponding product ID, the user clicks on the H5 page to jump back to the app native page.Method:First of all to determine whether the user is iOS or Android device (only consider iOS and Android, because it is still a bit different, so separate), and then disable the H5 page jump, get the cli

From the data to see the user behavior is a very interesting thing, understand the user behavior of the corresponding to our product design, thematic design optimization, can produce higher conversion rate of works. Here to share with you 10 of us from the recent mobile phone data extracted from the small summary, I hope to help you. 　1, in the case of mobile resources push only, the phone page access hea

Sometimes some data needs to be displayed dynamically, and it needs to be wrapped, but the client doesn't know where the data should be wrapped.and follow the background editing format to display, so the background directly returns the background edit H5 string, but the data has been JSONResolved, and then go through t
