What is a Data Center Rating? The data center rating system was designed by the Uptime Institute to classify data centers based on several criteria primarily related to uptime, fault tolerance, and availability. The rating system is designed to allow each company to independently understand how a particular data center will perform according to its needs and what can be expected from that data center. Uptime Institute divides the core standards into one to five levels. This global standard allows organizations to compare any two data centers around the world. The final certification highlights the design, structure and operation of the data center. What is a Tier 1 data center? A Tier 1 data center is the most basic type of data center. Tier 1 data centers have dedicated IT service space and equipment located outside the office, uninterrupted power supply, backup power usually provided by internal generators, and computing equipment cooling equipment. Tier 1 data centers also have systems, protocols, and equipment in place to ensure they can remain up and running during normal business hours (such as nights and weekends). What is a Tier 2 data center? Tier 2 data centers have redundant components that provide additional capacity over Tier 1 data centers. These components include diesel generators to provide backup power, pumps or chillers for more reliable additional equipment cooling, and specialized UPS modules to provide reliable power that eliminates voltage dips and spikes. What is a Tier 3 data center? Tier 3 data centers have systems, protocols, and equipment in addition to Tier 2 data centers, allowing personnel to perform upgrades, repairs, and/or changes without shutting down any equipment. Since everything is available simultaneously, teams can make any changes as needed without disrupting service to customers/end users. What is a Tier 4 data center? Tier 4 data centers are equipped with fault tolerance mechanisms on the basis of Tier 3 data centers. The idea is that data centers can stop and prevent certain problems from happening in the first place. The goal of a Tier 4 data center is to provide continuous support and service under any circumstances, and it is the highest level that the Uptime Institute classifies a data center. What is a Tier 5 data center? Tier 5 certification means the data center has met the highest standards for uptime and resiliency in the market today. Level 5 certification was originally developed by colocation and cloud services provider Switch in 2017, and is technically distinct from the four core levels proposed by the Uptime Institute. What is the highest level? According to the Uptime Institute, no level is "better" than another. They believe that businesses should choose a data center that meets their specific needs regarding cost, availability, and more. What is Uptime Institute? Uptime Institute bills itself as an independent advisory body that provides third-party guidance and oversight to the data center industry. Its core mission includes supervising data centers and issuing certificates to give end users of data centers a reason to decide which data center to use. Like 451 Research, Uptime Institute is also a division of The 451 Group.

Product Name Communication Base Station Data Center Description With the continuous development of information technology and the maturation of 5G technology, efficient management of base stations is becoming increasingly important to ensure everyday communication. However, how to build and operate these base stations is a problem many people are facing. When comparing dedicated base stations to integrated cabinets, many people are opting for the latter.Building a dedicated base station requires careful site selection, a longer construction period, and more time and labor costs. Once built, expanding the usable space is more difficult. In contrast, the integrated cabinet is easy to install, takes up less space, requires less time and labor costs, and can be delivered within a day. In addition, the cabinet is sturdy, corrosion-resistant, and can protect internal equipment well.Through a comparison of dedicated base stations and micro data center, we can directly see the pros and cons of each. This is also why more and more people are choosing to use micro data center to set up base stations. Of course, if there is still space available in an existing dedicated base station, it can be renovated to save costs. However, if there are no old machine rooms available, using an integrated cabinet for construction will be faster, easier and more cost-effective. The base station remote maintenance system can help you realize the efficient management of the base station.The system is equipped with monitoring hosts and front-end sensors installed in the integrated cabinet, which can monitor leaks, smoke, door magnets, UPS, and lightning protection devices inside the cabinet, helping customers achieve efficient management.

With the gradual popularization of cloud computing, big data, and IoT applications, data centers are developing in the direction of green energy saving, modularity, and intelligence, keeping the balance inside the data center is the key to influencing the data center, and one of the influencing factors to keep the balance inside the data center is the power supply, so the next article will combine the types and installation methods of PDU (rack mount power distribution unit) power outlets to show you Therefore, this article will show you how to choose the PDU (Rackmount Power Distribution Unit) power outlets to best ensure the balance of power supply for the equipment in the cabinet. What is a PDU (Rackmount Power Distribution Unit) power outlet? PDU (Rackmount Distribution Unit) power outlet is an electronic device that provides safety protection for various electronic devices, instruments and instruments, and communication lines. When the electrical circuit or communication line because of external interference suddenly generated a spike current or voltage, a PDU (rack mount power distribution unit) power outlet can be a very short time on the shunt, to effectively avoid damage to other equipment in the circuit surge. Every network system needs to use the PDU power outlet, it can provide power for the equipment in the system to ensure normal operation, so the PDU power outlet is the necessary equipment in the network system. The function of PDU power outlet PDU power outlets are generally used in various fields such as data centers, distribution rooms, industrial plants and mines, production workshops, computer rooms and enterprise shopping malls, etc. In these application environments, the main functional role of PDU power outlets is reflected in the following three aspects: 1. the ability to provide a sufficient number of outlets that can be used to support the growing demand for networks; 2. the ability to help network administrators track the power consumed by devices, and provide safe and reliable power for devices that need power at any time; 3. can automatically detect the current and voltage, with the role of power supply overload protection. The difference between PDU power outlets and ordinary sockets What are the differences between PDU power sockets and ordinary sockets? Mainly reflected in the following five points: 1. The two functions are different Ordinary sockets only have the function of power supply overload protection and general control switch, while PDUs not only have power supply overload protection and general control switch but also have the functions of lightning resistance, anti-voltage, anti-static, and fire prevention. 2. The material of the two is different The common socket is made of plastic, while the PDU power socket is made of metal, with an anti-static effect. 3. The application areas of the two are different Ordinary outlets are generally used in the home or office to provide power for computers and other appliances, while PDU outlets are generally used in data centers, network systems, and industrial environments, installed in equipment racks to provide power for switches, routers, and other equipment. 4. The load power of the two is different The common socket cable configuration is weak, its current number is generally 10A/16A, and the rated load power is 4000W, while the PDU power socket configuration is better than the configuration of the common socket, its current number can be 16A/32A/65A and so on to meet more needs, its rated load power can be more than 4000W, to meet the requirements of the server room power. And when the PDU power socket load is too large, it can automatically power off, with a certain fire function. 5. The service life of the two is different The life span of ordinary sockets is generally 2~3 years, and the number of insertions and removal is around 4500~5000, while the life span of PDU power sockets can reach 10 years, and the number of insertions and removal is up to 10000, which is more than 5 times of ordinary sockets. PDU (rack mount power distribution unit) power outlet installation and points to note There are two main installation methods for PDU (Rackmount Distribution Unit) power outlets, which are horizontal and vertical installation: ① Horizontal 482.6*44.4*44.4 mm (1U) rack-mountable PDUs, mainly used with open frame racks and equipped with audio/video equipment. ② Vertical type 0U PDUs make the power distribution outlets closer to the equipment being powered. This mounting style is preferred by data centers because they do not take up rack space and require shorter power cords and easy cable routing management. This type of installation ensures that each power cord is routed in an organized manner. In a data center application environment, it is recommended to choose a vertically mounted 0U size product whenever possible, which makes efficient use of space and reduces cable routing clutter. When using PDU power outlets, we should pay attention to the following four points: 1. Please do not touch the power plug or connector with wet hands. 2. Do not use the PDU power outlet near the water. 3. Do not install the PDU power outlet near any heat source, such as radiators, heaters, amplifiers, stoves, and other heat-generating devices. 4. Do not attach metal objects or any other conductive materials to the power cord of the PDU power outlet. How to choose a PDU (rack mount power distribution unit) power outlet In most cases, choosing the best PDU (rack mount power distribution unit) power outlet will often involve hundreds of models, as well as other challenges such as considering system availability and the ability to power higher power density devices. Once a rackmount PDU is selected, IT administrators need to consider whether the product can support the next generation of IT equipment, taking into account factors such as power capacity, outlet type, and number. Different PDUs (rackmount power distribution units) have many different product features, power ratings, and types of input and output cable connections. Choosing the right rackmount PDU is sometimes not easy, especially when you don't know exactly what equipment is installed in the rack. New trends, including virtualization, converged infrastructures with computing, storage, and networking, and the need for high efficiency, make it important to think holistically about how to choose a rackmount PDU. Choosing the right rack PDU for a particular rack requires information about the equipment in the rack, the power distribution at the site, and the need for other ancillary features. In most cases, there is an "inside-out" sequence for selecting a PDU (rackmount power distribution unit) power outlet: ① Determine the type and number of output outlets; ② Estimating the power distribution capacity; ③ Determine the type of input sockets; ④Select the visualization function and control option of the branch circuit; ⑤ Selecting the appearance and installation method. Summary PDU power outlets have functions that ordinary outlets do not have, and I believe that in the future, PDU power outlets will not only be used in network systems but will also replace ordinary outlets in thousands of homes.

What is Data Center Cooling? Data centers require a cool environment for the processor to function successfully, because excess heat can damage the systems and result in data loss or interrupted information flow. In data centers, cooling systems are used to prevent such damage and preserve the air temperature within acceptable limits. Data center cooling solution is used to maintain ideal environmental conditions for information technology equipment (ITE) operation. The technology eliminates ITE heat and transfers it to the heat sink. Thus, it can be inferred that data centers cannot function efficiently and can result in a system failure in the absence of an appropriate cooling system. Why do data centers need cooling? One of the most important and less understanding processes in the critical IT environment is data center heat removal. As the latest computer equipment is smaller and uses the same or more electricity than the replaced equipment, more heat is generated in data centers. Precision cooling and heat rejection systems are used for collecting and transporting this undesired heat energy into the outer atmosphere. 1. Increasing need for energy-efficient data center facilities The energy consumption in the ICT sector has increased exponentially in recent years. The data centers, recently experiencing unprecedented growth in size and population, form an integral part of today’s ICT. The Tech giants such as Google, IBM and Microsoft have large cloud and app hosting data centers. Several studies have been established for energy consumption of data centers, these studies emphasize upon the rising need for evolving strategies for energy efficiency. Heat generated from highly populated data centers requires huge cooling units to maintain the temperatures within the operational range. 2. Rising shift toward digital transformation through connected technology Lately, digital transformation has gathered a lot of attention. It not only includes deployment of new technologies, but also the alteration of business processes and models that can completely leverage such technologies. It helps organizations to obtain unmatched productivity levels, improve customer experience, influence innovation and enlighten competitive benefits. Digital transformation is altering the nature of the data center, and novel technologies are rapidly placing more demand on data centers and data center services. Types of Solutions · Air Conditioners In basic terms, air conditioning involves removing heat and humidity from the inside of an occupied area to improve the occupants comfort. In both domestic and commercial environments, air conditioning can be used. This process ensures a more comfortable interior environment for humans, however air conditioning is also used to cool/dehumidify roommates filled with electronic heat-producing devices such as computer servers, power amplifiers, and some sensitive products, like artifacts, even for display and storage. · Precision Air Conditioners Precision air conditioning is designed to manage sensitive heat (humidity without the emanation of a machine), while latent heat (humidity with the emanation of persons) is managed with comfort/standard air conditioners. Designed for many different applications, high-precision air conditioning including cooling of the data center, medium and low-density server environments, telecom switching systems, medical operating theaters, and a clean-room environment is essential. · Chillers Data centers constitute a mix of computing elements, networking infrastructure, storage systems along with power management and cooling capabilities all of which offer opportunities for improving energy efficiency and achieving more sustainable data centers. With air-cooled chillers, heat is removed from the returning chilled water is rejected to a device called an air-cooled condenser that is typically integrated with the chiller. This type of chiller is known as a packaged chiller and can also be integrated into a cooling facility module.

1. different basic concepts Ordinary air conditioners generally include household air conditioners, central air conditioners in residential areas, and air conditioning systems in offices and commercial office buildings. The function of this type of air conditioner is to create a good living environment for indoor air, provide people with a comfortable working and living environment, and make people in this space feel comfortable. The precision air conditioner is designed to meet the requirements of the special process and specific environment of the precision equipment. Its purpose is to precisely control its temperature, humidity, etc. and require it to be controlled within a certain range. It is also called constant temperature and humidity air conditioner, which is characterized by large air volume and heat load Variety. 2. Product focus Due to different design uses, the product focus will also be very different. Ordinary air conditioners are designed to "provide people with a comfortable working and living environment". Its applicable object is people, and its application scenarios are mainly in semi-open areas where people are active: such as living rooms, bedrooms, exhibition halls, offices, etc. Ordinary air conditioners do not have the function of "constant temperature and humidity", and the temperature difference range is 1 °C. Therefore, ordinary air conditioners pay more attention to the design of comfort, low noise, low air supply and low wind speed during use. Precision aircond are designed to "provide a specific operating environment with constant temperature and humidity for precision devices such as IT equipment". This is a high-precision air conditioner specially designed for computer rooms. In order to ensure good heat dissipation of computer or server chips, the application scenarios include computer rooms, laboratories, large medical equipment rooms and other high-precision fields. Its service object is related equipment that maintains the continuous operation of the computer room: such as IT equipment, power distribution system, power supply equipment, etc. The precision air conditioner has the function of "constant temperature and humidity", and the temperature difference range can be controlled at 0.1 degrees Celsius or even higher. Therefore, precision air conditioners pay more attention to the design of precise control of temperature and humidity in the equipment room and timely control of cleanliness. 3. Different control systems Ordinary air conditioners only have a basic control system. According to their own heating and cooling needs, people operate through the infrared remote control or the smart remote control downloaded from the mobile APP. The intelligence is relatively moderate; and cooling and dehumidification can only be performed at the same time. Direction local air circulation. Precision air conditioners have a high-precision, responsive, microprocessor-based intelligent control system that can quickly respond to changes in the external environment, thereby ensuring that environmental changes remain within the setting range required for a stable environment. For example, human-computer interaction interface, alarm protection, network monitoring and other functions. 4. Different degrees of air filtration Ordinary air conditioners use coarse filters, which cannot remove enough dust particles. The dust will adhere to the high-efficiency chips to a large extent, which will seriously affect the service life of related components and cannot meet the purification requirements of computers. Most common air conditioners use residential-type air filters with a filtration efficiency of only 10%. This is not enough for a data center environment. The precision air conditioner uses a high-efficiency filter, its efficiency can reach 20%~30%, and it meets the ASHRAE standard, which can filter out the dust in the air in a timely and efficient manner, which can effectively prevent the dust from adhering to the high-frequency chip and cause a short circuit due to carbonization. Improve the cleanliness, prolong the service life of related parts, and reduce operation and maintenance costs. 5. Different operating performance and cost Common air conditioners used in most office buildings run for an average of 8 hours a day, 5 days a week, while some commercial places, such as supermarkets and shopping malls, run an average of 12 hours a day, 7 days a week. Sometimes there are environmental changes or special needs that increase the runtime. For precision air conditioners, no matter what the external environment is, most data centers require uninterrupted operation 24 hours a day, 365 days a year. And those ordinary air conditioners with outdoor heat exchangers generally cannot operate when the external ambient temperature drops below 32°F because the pressure is too low. However, precision air conditioners operate normally at -30°F, while glycol refrigeration systems cool normally at -60°F. Although the initial investment of precision air conditioners is basically much higher than that of ordinary air conditioners. However, the annual operating cost of ordinary air conditioners is higher than that of precision air conditioners by $243/per ton of sensible cooling capacity. This is consistent with the principle generally recognized by the industry, that is, the refrigerating capacity of 3 ton of ordinary air conditioner is equivalent to 2 ton of refrigerating capacity of precision air conditioner. Therefore, for those small projects, in the case of sufficient funds, it is recommended to consider both the initial investment and operating costs; and for some large projects, it is still recommended to use precision air conditioners, which are designed for uninterrupted operation throughout the year. Intelligent control system, constant temperature and humidity functions, components and redundant functions, etc., will greatly improve the reliability of equipment operation, and will greatly reduce operation and maintenance costs in the later stage.
