With the popularization of IT technology, the demand for IT equipment has shown explosive growth. IT systems are becoming more and more dense. The computer rooms are becoming crowded. The originally spacious computer room space is gradually occupied by large and small cabinets. At the same time, the cabinet The number of servers and switches has also increased greatly. The overall temperature of the equipment room and the temperature in the cabinet have risen rapidly, and the heat generation of the equipment room and the difference in the layout area may even appear in some data centers. Although the temperature in the equipment room It has dropped to more than 10 degrees, but some areas are too cold and some are insufficiently cooled. Some cabinets still have the embarrassing situation of temperature alarms. The investment in cooling power consumption accounts for an increasing proportion of data center energy consumption.
I want to choose a blade server, but also worry about the following problems: improper heat dissipation brings local hot spots and high energy consumption; the power supply system is difficult to meet power consumption requirements; there is not enough cooling capacity; space density design and load-bearing make people headache, etc. More reasonable placement, more ventilated cabinets, and even row cooling or water cooling are used to reduce the cooling load in the computer room.
The above problems can be attributed to the greening of high-density equipment and even high-density areas in the computer room to the high-density computer room. Combined with many years of design and construction of large data centers, operation and maintenance service management practices, some green solutions for high-density areas of computer rooms are proposed.
First of all, you should clearly grasp the energy consumption of various loads in the computer room and further have a unified control over the power consumption of the entire computer room. IBM has launched a software called Power Configurator, which can plan the power consumption of blades and x-series servers. Through it, users can plan the power consumption of these types of servers in their own data centers, and also in the data center. During the upgrade, it is reasonable to predict whether the power redundancy of your computer room can meet the requirements of the new IT system. HP has also launched a software called Power Calculator Links, which can plan energy consumption for Proliant servers, blade servers and some storage devices. However, these two software are designed for a certain type of product, if you want to save energy, you must have a unified control of the power consumption of the entire computer room. At present, APC-MGE provides management and monitoring software that can manage all equipment from the PC to the entire building, and APC-MGE ’s parent company Schneider has a software that can provide monitoring from the building to the power plant. Integrate into one. This configuration tool can actually measure the power consumption value according to the equipment used by the user, ensure that the power supply and cooling supply equipped by the user are actually needed, and avoid the occurrence of excessive planning.
BANYANO proposed a smart management solution through a touch screen interface, focusing on the cabinet micro-environment where IT equipment operates. Through cabinet-level monitoring, cabinet group-level monitoring, and computer room environment monitoring, three levels of monitoring make local or remote management handy. The cooling, power supply, power distribution and other facilities of the entire computer room will be planned according to the energy consumption of these loads.

Second, the current distribution of the temperature field of the air conditioner in the computer room is not uniform, and problems such as local overheating or overcooling are the main reasons for the waste of cooling capacity and the consumption of unnecessary electrical energy. Without purchasing new products, the best way to make energy-saving adjustments is to change the air supply method, try to use cold and hot channels for air supply, and change the temperature field distribution inside the machine room to achieve a reasonable layout. The high-density computer room adopts the cabinet group deployment method. The double cabinet row layout or single row cabinet layout is close to the wall; the air conditioner can be inserted between the cabinet rows and placed at both ends of the cold aisle (or hot aisle). Change the air supply method to improve the cooling efficiency. Through the revolutionary horizontal air supply and the nearby cooling air supply method, it fully supports high-density cooling and supports the cooling load of a single cabinet. The innovation of the air supply method combined with the temperature and humidity decoupling design and the cold aisle closed design can increase the PUE from the traditional 2.2 to below 1.5. Taking the 100KVA IT load as an example, it can save about 620,000 kWh per year and the power saving rate is 32% , Equivalent to saving 620,000 yuan.
Second, BANYANO's five integrated systems in a high-density computer room can help solve high-density problems. The integrated high-density computer room is the best combination of five systems including the computer room environmental control system, intelligent module power distribution system, server cabinet system, air flow regulation system, and hierarchical monitoring system, paying close attention to the power supply environment and temperature environment of high-density equipment such as blade servers , To solve the challenges brought by high-density computing.
1) Computer room environment control system:
Temperature and humidity decoupling design, high sensible heat ratio up to 0.99, improve refrigeration efficiency. Unique horizontal air supply method, close to the heat source, with the nearest air distribution, according to demand. The number of air circulation has increased significantly, the temperature is collected accurately, and the cold distribution is adjusted in real time according to the temperature, which improves the efficiency and saves energy by more than 30%.
2) Smart module power distribution system:
High-density power distribution design supports dual-bus power distribution configuration. Three-phase load balance is realized inside the cabinet. Plug and play connection.

Localized monitoring interface, which can monitor the "microenvironment" inside the cabinet, including temperature, humidity, cleanliness, smoke, water leakage and other related information, and can realize localized monitoring through the cabinet monitoring module. The front design of the cabinet is open and the rear mesh door is designed, and the through hole rate reaches 70%. Support dense wiring, no tool installation wiring system, support upper wiring. The design power distribution capacity of a single cabinet is 10KVA, which can be easily expanded to 20KVA.
4) Air flow regulation system:
The closed channel system controls the air flow delivery path and provides high-density cooling protection. Significantly improve the cooling capacity utilization of the air conditioning system and reduce the energy consumption of the computer room.
