Data center automatic Transfer system basic components and technologies

Data center automatic Transfer system is a software and hardware combined with the complexity of the system, this paper will be the core of the management system for the monitoring software module composition, technology, application scenarios, such as a detailed introduction, provide necessary reference for system design.
The monitoring and automatic Transfer system consists of four major systems: monitoring system, running management system, total control center system and basic service system.

The following are detailed descriptions of the core modules in the four major systems.
I. Automatic Transfer system
The monitoring system consists of two main subsystems: information acquisition subsystem and information processing subsystem.
1. Information acquisition subsystem
For the realization of the modular design, distributed deployment, improve stability monitoring management system, information collection subsystem has basic hardware, namely by a hardware device or hardware module, instead of the traditional way of using pure software to realize the information acquisition function.
The main function of collection module is to provide various kinds of interfaces to access various monitoring management objects.
The second is to realize the protocol analysis of various collection information;
The third is to upload the parsed information to the processing unit in a uniform format.
2. Information processing subsystem
Information processing subsystem is the core of the monitoring management system to complete monitoring function subsystem, real time, flexible and accurate processing, computing, storage mass data, need to design several key modules: analysis of complex event processing module, adjusting control module.
(1) complex event analysis and processing module
The Complex Event analysis Processing module (CEP, Complex Event Processing) captures a variety of basic events first, then analyzes and collates to find more meaningful events (compound events).
The analysis and collation of events, and find out the compound event, is the core of CEP and the most difficult place.
Working principle of the complex event analysis module as shown in figure 1, real-time data as a source of access events dealing with bus, the CEP engine by specifying a rule, deal with the real-time data and historical data of cache, and through the event handling bus to provide meaningful event to the event consumer.
Is a typical application example, the data center power failure, the alarm will cause a lot of equipment, through the analysis of the complex event processing module analysis, can from the incident wave analysis the real cause of the alarm will all alarm merged into a power outage alarm equipment.
The complex event analysis and processing module needs to handle the sea events and deal with the pressure.
Complex event analysis technology is different from traditional database data processing, produced by real-time data flow driven event processing logic, in memory to complete all calculations, performance has an order of magnitude improvement, can satisfy the requirement of real-time processing.
Complex events analysis processing module of matching rules is the key to improve the effectiveness of the treatment, in use, when the monitoring object logical relations change, must maintain event matching rules, to ensure the correctness of the process.
(2) regulation and control module
To affect the user total control center system business system security equipment are the control principle, monitor not only the non-core business and systems, such as environmental monitoring equipment (such as: the new fan, lighting), security systems (such as video surveillance systems, access control attendance system) can be receiving control input, such as can use this feature, by adjusting and control module to refinement, intelligent data center management.
There are two kinds of working mode of control and control module: one is manual adjustment and control, one is automatic adjustment and control.
The manual adjustment and control is relatively simple, which is made by people to judge, make decisions, form control instructions, and send them to the corresponding equipment through the monitoring system to achieve the purpose of regulating and controlling.
At this time, the regulation and control of the system rely on personal experience completely, the randomness is stronger.
The common manual adjustment and control mode has remote door opening, according to the temperature of the machine room, manually adjust the setting temperature of each air conditioner.
Manual adjustment and control can be done not only through the monitoring system, but also by phone, SMS, etc.
The difference between automatic regulation and control is that the human experience data is built into the monitoring system.
The monitoring system is based on these empirical data to form adjustment and control logic.
When the monitoring system data collected into the adjustment and control logic unit, the unit form expected adjustment and the control instruction, issued to the corresponding equipment, so as to realize the self-regulation of unattended.
One of the most common applications of the technology is linkage control, such as fire control fire linkage door access, door access linkage video video, fire fire linkage real-time video broadcasting, etc.
With the development of green data center, this technology is also gradually applied to the energy saving field of data center, such as air conditioning group control technology is an example of this kind of thought application.
