The uninterruptible power supply system is designed to ensure uninterrupted operation and protection of high-tech equipment in the event of a power failure or its parameters go beyond the permissible limits, thereby ensuring the continuity of the Customer's business.
Uninterruptible Power System Structures
Distributed structure of an uninterruptible power supply system
However, the use of this system may be limited by the following factors:
Centralized structure of an uninterruptible power supply system
The use of this system may be limited by the following factors:
In its pure form, each of the considered systems is rarely used. The use of a centralized system is advisable when the concentration of equipment that performs a single task and consists of components of the same reliability class and the same energy consumption characteristics.
For optimal investment spending, a two-tier system is used, which is a combination of a centralized and distributed system. The task of optimizing such a system in terms of power and cost of equipment consists in determining the most responsible consumers and minimizing the number of consumer groups by appropriately configuring the local computer network.
When choosing a two-tier structure, in addition to installing one high-capacity UPS (or a set of parallel-functioning UPSs), some are protected using local UPSs of lower capacity. The goal is to protect equipment such as file servers, LAN management workstations, communications equipment, communications systems from power outages due to cable failures within a building.
When creating an uninterruptible power supply system, RittalRimatrix solutions - PMC 200, PMC 120, PMC 40, PMC 12, APCInfraStruXure - SymmetraOdin are used. Symmetra PX, Smart VT, Smart UPS.
The guaranteed power supply system is designed to ensure uninterrupted operation and protection of high-tech equipment in the event of a power failure or its parameters go beyond the permissible limits, thereby ensuring the continuity of the Customer's business.
The division of loads by type allows you to reduce the load on the uninterruptible power supply (UPS), which, in turn, increases the battery life of the UPS in emergency mode and makes it possible to use a UPS with a lower capacity.
In this case, the UPS provides galvanic isolation between the power supply networks of computer and communication equipment and the power supply network of technological equipment (in particular, air conditioning systems). This makes it possible to significantly reduce the level of interference in the protected power supply network when switching on and off equipment characterized by a non-linear type and large starting values of current consumption.
Electrical load types
Modern high-tech computing and telecommunication equipment is sensitive to the smallest changes in the environment. A prerequisite for ensuring its normal performance is maintaining strictly defined temperature conditions and humidity levels. The air conditioning system for such facilities must be highly reliable and ensure the continuous maintenance of the optimum temperature, humidity and air purity in the room. This is especially true for data centers, without which it is impossible to imagine modern business.
The industrial air conditioning system (hereinafter referred to as IACS) is designed to maintain the required parameters of the microclimate of the IT equipment of data processing centers, communication operators' nodes, centers of Internet service providers, hosting centers, various TV and radio transmission stations and other information technology facilities.
The main source of cold for all types of IACS can be either a freon system with direct cooling and a remote condenser, or a chiller (liquid) cooling system.
The type and composition of the IACS is determined at the stage of developing a technical solution, taking into account the capacity of the cooled equipment, requirements for reliability, efficiency, scalability and controllability of the system, design and technological limitations, investment volumes and implementation timeframes. When choosing equipment, preference is given to innovative developments of leading manufacturers of climatic technology, providing energy-efficient cooling of IT equipment.
Room-level cooling involves one or more precision air conditioning systems operating in parallel, which not only provide cooling to the equipment, but also act as a large mixer that mixes the air in the room to achieve a uniform average temperature and prevent localized hot spots.
In row-level refrigeration architecture, air conditioners supply cold air to the space between the rows. The equipment is located on a hot / cold aisle principle, which makes the air circulation predictable and allows the full rated cooling capacity of the air conditioning system to be utilized.
When cooling at the rack level, the air conditioning units are structurally connected to the rack, which initially presupposes a high density and power of IT equipment. The air circulation paths in this architecture are clearly defined and do not depend on the characteristics of the room. Using this cooling method allows the deployment of equipment with a total consumption of over 30 kW in a single rack.
When creating an industrial air conditioning system, innovative developments and solutions from leading manufacturers of climatic equipment - Emerson Network Power, Rittal, APC by Schneider Electric, Stulz - are used, providing effective cooling of IT equipment with a capacity of several kilowatts to several megawatts.
The system for monitoring and managing the engineering infrastructure of a data center is a software and hardware complex designed for remote collection of information on the state of equipment of various subsystems, as well as environmental parameters (temperature, humidity, smoke), in order to respond quickly in case of emergencies ( fire, accident, penetration of unauthorized users).
The use of a monitoring and control system helps to eliminate the problems associated with the operation of the engineering infrastructure of the data processing center, increases the reliability of equipment operation, and also reduces the response time to an event.
The use of a monitoring and control system greatly simplifies the process of administering engineering systems of a data processing center, allowing you to quickly receive information about the state of all systems at a given point in time.
