Intelligent Transformation: Intelligentization of Engine Room Drives Management Efficiency

Recently, Zhou Houjian, chairman of Hisense Group, put forward a high-profile report on "Reimagining Your Thoughts" and proposed a comprehensive and intelligent development strategy in the coming decade. This goal has once again pushed smart applications to the public's spotlight. It should be noted that intelligentization is not fully realized by one or two companies. It requires the joint efforts of many companies and large-scale R&D of technology to support the practical application of intelligent systems. In contrast, the intelligent application development of computer room management is rapidly developing and has surpassed the application in other fields, making the management efficiency of the computer room to the extreme...

The computer room project design experts pointed out that as a complex system, the intelligentization of the engine room is not just the intelligence of certain devices. It includes three different aspects of intelligence: the intelligentization of the computer room construction environment (buildings), and the basic equipment management of the computer room Intelligent and intelligent server management. Building intelligence serves as the environment for the engine room system. Its safety management and energy consumption management are the external environment protection of the intelligent equipment room. The intelligent management of the hardware infrastructure equipment of the engine room is the key to making the hardware equipment of the entire computer room run safely and reduce the failure time. Smart management of servers is a necessary condition to ensure that each server maintains a good state of operation at the lowest management intensity.

As far as building intelligence is concerned, as early as 2000, China issued the “Intelligent Building Design Standard GB50314/T-2000” standard, and in 2006, it issued the “Intelligent Building Design Standard (GB 50314-2006)”. With the Internet of Things in 2010, With the development of new technologies such as green energy conservation and data centers, building intelligence has attracted more and more attention from construction companies.

Emerson is the most respected supplier in the industry in terms of intelligent management of basic equipment in the engine room. It provides a relatively complete solution for monitoring, measurement, alarm, and notification of power supply in the equipment room, environmental temperature/humidity/smoke, etc. Program.

However, as far as the current application is concerned, the intelligence level of basic equipment management in the computer room is generally low. According to Ding Ruijun, Senior Engineer of Breakthrough Electrics, the application of intelligent PDUs in the three major domestic operators' rooms is still in its infancy, with a coverage of approximately 20%. And in some foreign mainstream operators, this figure can reach 80%.

Intelligent Management of Servers China is currently in its infancy, and domestic companies led by Haikang Technology have made intelligent development of their KVM and other devices for server control an important strategic goal for future development.

From the perspective of KVM products recently launched by Haikang, the intelligent matrix KVM switch is becoming a leading product of its product line, and it is trying to accelerate the development of intelligent server management in China. Looking at the EasyView 2000 and the series that have just been available to the market, this new matrix-based intelligent KVM enables two users to manage up to 1024 servers at the same time. Its intelligent design greatly reduces the work of the server administrators, greatly simplifies the cabling project, saves the space of the equipment room, and eliminates the user's troubles caused by the adjustment of the computer room cabling.

In addition, because of its intelligent design, the EasyView2000 series has the characteristics of high scalability, so that it has a good application flexibility in the application to adapt to the different size of the computer room.

In this regard, Haikang KVM responsible person said that the intelligent development of server management is an inevitable trend of computer room management, an increasingly large server group management needs to simplify the management through intelligent management, so that managers from the complex and inefficient work to relieve themselves .

Intelligence: the ultimate in management efficiency

In the entire development of mankind, more and more jobs are replaced by tools and equipment, freeing people from lower-level labor, and focusing on more creative work is always the direction of development. The demand for labor costs and reliability in modern society is increasing day by day, and companies are expected to hand over more and more jobs to machines and reduce labor costs. At this point, room management is no exception.

For a computer room, a 10% increase in management efficiency means a 10% reduction in personnel costs. It is this motivation that has led to the history of the management model in which server managers used to push service control devices to and from server racks. When managers move from server racks to the central control room, the focus of management shifts from centralized control to intelligent control – managing servers with minimal effort, simplest cabling, minimal equipment, and smartest methods.

Haikang KVM technology experts believe that due to the relatively early management of the basic equipment room management, the current main strength of the management staff of the engine room lies in the management of the server. Therefore, server management is becoming the shortest board of the computer room management. Therefore, how to accelerate the intelligentization of server management is the key to improving the level of computer room construction in China.

Industry experts pointed out that there are already relatively mature standards in the electrical, temperature, and humidity aspects of the engine room, but there are currently no measurable benchmarks in terms of the management level of the engine room. The low level of management is another hidden “high energy consumption” in the construction of many computer rooms. Therefore, it is an important task for the current computer room construction to comprehensively speed up the intelligentization of computer room management.

In comparison, intelligence in specific areas such as the computer room is lower than the intelligence of consumer applications, and it is easier to achieve goals. Moreover, more and more enterprise users have realized the economic and social significance of their computer room (and other fields). Therefore, it can be predicted that in the next few years, the intelligent development of industrial applications will surpass the application in the field of home applications and become the pioneer of smart applications in China.

A circulator is a passive non-reciprocal three- or four-port device, in which a microwave or radio frequency signal entering any port is transmitted to the next port in rotation (only).


Applications

Isolator

When one port of a three-port circulator is terminated in a matched load, it can be used as an isolator, since a signal can travel in only one direction between the remaining ports.[12] An isolator is used to shield equipment on its input side from the effects of conditions on its output side; for example, to prevent a microwave source being detuned by a mismatched load.

Duplexer

In radar, circulators are used as a type of duplexer, to route signals from the transmitter to the antenna and from the antenna to the receiver, without allowing signals to pass directly from transmitter to receiver. The alternative type of duplexer is a transmit-receive switch (TR switch) that alternates between connecting the antenna to the transmitter and to the receiver. The use of chirped pulses and a high dynamic range may lead to temporal overlap of the sent and received pulses, however, requiring a circulator for this function.

In the future-generation cellular communication, people talk about full-duplex radios, where signals can be simultaneously transmitted and received at the same frequency. Given the currently limited, crowded spectrum resource, full-duplexing can directly benefit the wireless communication by twice of the data throughput speed. Currently, the wireless communication is still performed with "half-duplex", where either the signals are transmitted or received at different time frames, if at the same frequency (typically in radar), or the signals are simultaneously transmitted and received at different frequencies (realized by a set of filters called a diplexer).


Reflection amplifier

reflection amplifier is a type of microwave amplifier circuit utilizing negative differential resistance diodes such as tunnel diodes and Gunn diodes. Negative differential resistance diodes can amplify signals, and often perform better at microwave frequencies than two-port devices. However, since the diode is a one-port (two terminal) device, a nonreciprocal component is needed to separate the outgoing amplified signal from the incoming input signal. By using a 3-port circulator with the signal input connected to one port, the biased diode connected to a second, and the output load connected to the third, the output and input can be uncoupled.
