Server load density of modern computer room construction
There is no quick solution for the construction of server rooms. Standardized module design or manufacturing more products to create the server room environment has become a trend, rather than the traditional "structured" unique environment. According to the problems or failures encountered in the process of building the server room in the past, many good practices are summarized. But these are overall design solutions, and the important thing is that those solutions do not include the construction of unique server rooms.
The construction of server room is divided into two parts. This article is the first part, and the second part will be presented later.
With the continuous growth of technology, the construction of server rooms has become a common phenomenon. What problems need to be solved during the construction of the server room? The two articles in this series help you identify several factors to consider when building different physical systems according to the defined personalized requirements.
What is the server room? There are many kinds of definitions, but they cannot be explained here because of the large number. This article will focus on the introduction of the space equipment of the computer room and the existing configuration facilities technology inside the building. Whether it is office space, storage space, institutional space of medical facilities or any other type of usable space.
The key is that you should know that there is no overnight solution for the construction of server rooms. Standardized module design or manufacturing more products to create the server room environment has become a trend, rather than the traditional "structured" unique environment. In many cases, the manufacture of standard products can ensure the construction of a standard server room.
According to the problems or failures encountered in the process of building the server room in the past, many good practices are summarized. But these are overall design solutions, and the important thing is that those solutions do not include the construction of unique server rooms.
Many factors need to be considered in the construction of server room, which can be divided into two categories: defined requirements and building system considerations.
Defined requirements require load density, elasticity, growth, modularity, and flexibility.
Find out the load density of your computer room
Traditionally, the load density is expressed in watts per square foot (W/SF). Although W/SF has played a role in the server room, it is more meaningful to use the maximum average value of kW per unit (kW/unit). These two numbers represent most of the requirements of the drive's electrical and mechanical systems. For example, the space of the electrical and mechanical system can support 3.5kW/rack on average, and the maximum of 5kW/rack is very different from the average of 10kW/rack and the maximum of 12kW/rack.
Density drives affect not only system capabilities, but also system configurations. There are many examples where density affects the configuration of mechanical systems, such as centralized cooling, underfloor cooling, isolation of hot and cold air flow, etc. At the same time, the drive system configuration will have a certain impact on energy efficiency. For example, isolate hot and cold air. At higher kW/rack density, correct operation is necessary. At low kW/rack density, the equipment is used for airless isolation to achieve cooling purpose. Although cold and hot air are separated, the energy efficiency will increase significantly. So the server room must be constructed with separated airflow? This depends on the unique business requirements of the enterprise, and also the higher installation costs.
When the construction of server room is different due to mismatching of system capacity, it is usually to limit the load of mechanical system. The general number of load density must be applied to each component of the system as a whole, otherwise it will result in the system capacity retention and waste of cost.
