It can maintain the operation of the system with lower cost and less personnel input, providing high efficiency and high efficiency.
 
manageability
 
Due to the complexity of the intelligent computer room system, with the continuous development of business, the task of management will become increasingly onerous. Therefore, in the design, a comprehensive and perfect management and monitoring system must be established. The selected equipment has intelligent and manageable functions. At the same time, advanced and management monitoring system equipment and software are selected to realize advanced centralized management monitoring, real-time monitoring and monitoring of the operating status of the entire system, real-time lighting and voice alarms, and real-time event recording. , so that the fault can be quickly determined and the maintenance work of the management personnel is simplified, thus providing the most powerful guarantee for the safe and reliable operation of the system.






1.2 Cabinet System of Micro Module Data Center Cabinet System
The cabinet is a 19-inch standard high-strength cabinet with a capacity of 42U. Cold-rolled steel plate, the thickness of the steel plate is more than 1.2mm, and the surface is sprayed with plastic; anti-rust, waterproof and anti-corrosion.
A hot aisle structure is formed at a position of 200mm at the rear of the cabinet, and the hot aisle area is specially closed. The rear door is a fully enclosed steel plate door, all door seams are filled and sealed with sealing strips, and the side doors are multi-curved. The process is closed, and the hot air is effectively centralized and controlled to ensure that the hot air in the hot aisle does not escape to the space outside the equipment room. The side doors of the modular cabinet are assembled with two left and right side doors. In the open state, after the cabinets are assembled side by side, a closed hot air channel is formed, and the hot air emitted by the servers, CPUs and other equipment at the front of the cabinet is centrally managed in the hot channel area, and the evaporative cooling system is installed side by side. The airflow absorption equipment (with high-density airflow absorption holes) on the side of the intercooling system is used to uniformly recycle the hot airflow.
In order to realize the separation of hot and cold aisles in the data center room and ensure the circulation of cold and hot air flow, in addition to the premise that the overall data center is closed, the most important thing is to deal with the air flow sealing and guiding structure processing of a single modular cabinet; cabinets Except for the 19-inch equipment installation position, the two sides, top and bottom have a unique closed wind shield design (taking into account the function of cable management) to ensure that all cold air can only flow through the server equipment (blow the server to dissipate heat). Control the flow direction of hot and cold air, thus greatly improving the utilization rate of air flow.
 
1.3 Power supply and distribution system of micro-module data center cabinet system
 
Precision power distribution cabinet is a power distribution cabinet that comprehensively collects all power supply conditions in the data center room.

3. Suggestions for model selection analysis of data center computer room
 
The following figure shows that HP divides the equipment load in the cabinet into 3 grades:
 
The cabinet load is less than 8KW (5kw in China), which is a small density, and the conventional room-level air-conditioning refrigeration method can meet the demand;
 
The load of the cabinet is 15KW-5KW, which is medium and small density. It needs to adopt the precise air supply method of row-level air conditioner or room-level air conditioner, and the cooling method of sealing the cold and hot aisles can meet the demand;
 
When the load of the cabinet is greater than 15KW, due to the high heat density, the row-level heating and cooling aisle sealing and precise air supply must be adopted.
The inter-column cooling system has high reliability, flexibility, dynamic cooling, and has the ability to adapt to the rapid update and change of the computer room load. It can realize the operation of multiple sets of units, and can realize joint control, and a maximum of 32 units can be controlled in a group for unified management.
Row-level cooling: high-performance row-level air conditioners, air-cooled/chilled water options, front air supply and back air return, horizontal air supply distance is only 2-6m, not limited to air ducts and perforated floors, air supply efficiency Greatly improved, perfectly matching high-density + closed hot and cold aisle scenarios, greatly reducing PUE, and solving local hotspot problems;
 
For example, the number of existing cabinets is 22, and the power of a single cabinet is 3KW. Considering that the row-level precision air conditioner is used for cooling, the cooling method of this solution has very little loss. It does not need to be calculated according to the traditional algorithm, and can be calculated as follows:
 
Total cooling capacity Q = equipment load + redundant load (10-20% of equipment load)
 
=22KW×3×1.1 =72.6KW
 
Because the computer room of this scheme is designed in accordance with the national class B computer room standard, all the refrigeration equipment needs to be configured with N+X redundancy, that is, the refrigeration equipment needs to have fault-tolerant redundancy. In this scheme, we use 4 row-level precision air conditioners. The cooling capacity of the air conditioner is 25.5KW, and the sensible heat ratio is 100%. 3+1 redundant configuration, the cooling capacity of 3 air conditioners is 76.5KW, which can meet the cooling demand of the computer room. Another air conditioner is used as a redundant configuration, and 4 air conditioners are used for cooling rotation to provide the service life of precision air conditioners.
 
Choice of cooling method
 
Conventional precision air conditioners have four cooling methods: air cooling, water cooling, chilled water cooling, and ethylene glycol cooling.
 
According to the computer room, two kinds of precision air-conditioning units, air-cooled and chilled-water-cooled, are mainly used. The characteristics of air-cooled and refrigerated water-cooled units are now compared in order to provide the optimal solution.
 
Principles of air-cooled and chilled water-cooled air conditioners
1.5 Cold aisle system of micro-module data center cabinet system
 
Cold aisle sealing components mainly include top sealing plate and aisle sliding door, single-row sealing components and double-row sealing components are provided according to the site environment
Each aisle top plate has the same width as the cabinet and is fixed to the cabinets on both sides. The material is flame-retardant plexiglass + sealing strip + metal frame, the thickness of flame-retardant plexiglass is 4mm; the color is fully transparent, and the metal frame is black matt fine sand grain; it does not affect the lighting, and there is no need to add lighting in the channel.
 
In order to better solve the hidden dangers of fire protection in the data center, we designed the channel roof that works in conjunction with the fire protection system. The 220V commercial power is transformed into 12V DC after the power adapter is converted to supply power to the magnetic lock. The magnetic lock keeps the flip plate and the outer frame closed when the power is on, so that the channel can be sealed; when the fire protection system sends out a fire alarm signal, The circuit breaker receives the signal and turns off the switch. At this time, the power of the magnetic lock disappears, and the top plate turns around the rotating shaft under the action of gravity. It can be opened instantaneously within 0.5 seconds, and the opening area is not less than 30% of the total area of ​​the top partition plate. To achieve the required channel for fire-fighting gas discharge, open the fire-fighting gas to achieve the purpose of fire extinguishing. After the top partition is opened, it will not hinder the normal operation of other equipment components in the data center and the passage of personnel in the cold aisle.
 
The entrances at both ends of the aisle of the data center are closed with sliding doors, the material is tempered glass with metal frame, and the thickness of tempered glass is not less than 5mm; the inside of the aisle can be clearly seen, the door is double-layered, and the handle is installed, and the door opening method is hinge + double door + Smart locks can be opened both inside and outside the channel;

With SHIP's high-performance Category 6A connection hardware, it provides users with more optimized transmission performance support, greatly reduces the loss of near-end crosstalk (NEXT) and far-end crosstalk (ANEXT), and meets the data transmission requirements of data centers. The jacket material is flame retardant (CMR) or low smoke zero halogen (LSZH) to ensure application safety.
 
New and expanded high-performance MPO or high-density pre-terminated optical system solution, consisting of high-quality optical cables and components, ensures forward-looking support for important data center links, including 10Gb/s, future 40Gb /s and 100Gb/s applications. The solution can be installed with a simple pull and plug operation, which is much faster than traditional field-terminated fiber connections.
 
The pre-terminated system consists of MPO pre-terminated optical cable, MPO pre-terminated module, MPO pre-terminated optical fiber distribution frame, etc. The pre-terminated fiber optic cable is in increments of 12 cores, using 50/125μm 10 Gigabit (OM3) multi-mode fiber or OS2 low-water peak single-mode fiber, plug end face B-type structure, and MPO-MPO or MPO-LC/ SC has a variety of interface methods. According to customer needs, it provides various types of pre-terminated optical cables with different core counts, different lengths, different end face structures and different interface methods to achieve high-performance and high-density fiber system connections.
