data center architecture

Cabinet server? The demand for IT equipment in our country is on the rise, and the business of each data center is developing rapidly. It often happens that the existing configuration of the data center that has just been built and put into use cannot meet the demand within one or two years. The expansion of the traditional data center in the later period does not have installation or installation is very difficult. Large, resulting in repeated construction and large waste of investment. The modular data center mainly includes a series of power equipment with modular design, such as uninterruptible power supply, refrigeration system, rack and remote monitoring system, etc., and the related modules are combined through a simple interface to form a complete data center. center. No matter what size the enterprise is currently in or what industry it is engaged in, it can customize the modular data center according to its own needs, and gradually expand the scale of the data center to meet more IT needs as business development demands. This means that enterprises can have several times the computing power in the future without any impact on the functionality or design of the existing data center. That’s what’s most charming about it.

Shanghai Huijue is committed to becoming a leader in the network connection industry

The cabinet is generally made of cold-rolled steel plate or alloy to store computers and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment orderly and neatly to facilitate future maintenance of equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

Server hosts, storage devices, and server cabinets should be arranged in partitions. Maintenance space should be reserved for hosts, storage devices, server cabinets, UPSs, air conditioners and other equipment according to product requirements, and the maintenance distance of adjacent equipment is allowed to overlap. The clear width of the aisle between the equipment should not be less than 1204mm, so that there is enough space for installation and maintenance. The cold aisle in the computer room is closed, and the equipment entering the computer room in stages and the relative positions of the reserved expansion equipment must not only conform to the process flow of the computer system, but also facilitate the entry and placement of expansion equipment and the connection of cables in the future.

The power environment monitoring system in the data room is a computer network composed of a complete set of computer network, database, communication, automatic control and new sensor technology. It is a computer technology-based, centralized management and monitoring automation system. , intelligent and high-efficiency technical means, the cold passage of the computer room is closed, and the monitoring objects are the power equipment in the computer room and the environment of the computer room.

The construction of a monitoring system can make full use of human resources, as well as strengthen the maintenance of stable operation of equipment and the safety of the computer room. The cold passage in the computer room is closed, which improves labor productivity and network maintenance level, so as to realize the transformation of the computer room from manned to few people and then to unattended. It can effectively promote the modernization of computer room maintenance and play a positive role. Is the cold aisle in the computer room closed?

The heat load of the computer room mainly comes from two aspects: one is the heat generated inside the computer room, and the cold passage of the computer room is closed, which includes: the heat generated by the indoor computer and external equipment, the heat generated by the auxiliary facilities of the computer room and the equipment in the computer room (electric heating, steam water temperature) and other heating elements). The calorific value is large in sensible heat and small in latent heat; heating of lighting (sensible heat); heating of staff (small in sensible heat and large in latent heat); heat generated by evaporation and condensation of water (latent heat).

The second is the heat generated outside the computer room, which includes: conduction heat, heat intruded through the building body, such as heat (sensible heat) introduced into the computer room from walls, roofs, partitions and ground; radiant heat (also called radiant heat) , the heat (sensible heat) directly entering the room from the glass window due to sunlight; the heat generated by convection, the heat (sensible heat, latent heat) generated by the high-temperature outdoor air (including water vapor) intruding from the gaps such as doors and windows; in order to make The heat generated by the fresh air (including sensible heat and latent heat) introduced by indoor staff to reduce fatigue and benefit human health.
