Take this opportunity , Talking about 《 Operation and maintenance management 、 Skillful and vulgar hands 》 

Operation and maintenance management objectives

As an operation and maintenance worker, the first thing I care about is how to reduce equipment downtime through preventive means 、 Failure and other problems cause business interruption , The second is how to realize immediate alarm or key link guarantee when finding problems , Guide and check regularly , In this way, even if there are problems, major accidents can be avoided , Finally, in case of failure , How to remove obstacles quickly and accurately , Minimize the loss .

All services for business ,“ More secure 、 More accurate 、 More timely ” It is the embodiment of our core value of operation and maintenance .

Operation and maintenance management background

The operation and maintenance work is complicated , Large Internet companies usually divide the operation and maintenance direction into : Application operation and maintenance （SRE）、 The system operational （SYS）、 Operation and maintenance R & D （DEV）、 Database operation and maintenance （DBA）、 O & M security （SEC） Five directions .  But no matter which position in operation and maintenance , Can't escape from asset related work .

System operation and maintenance responsibilities include the construction of basic services of the data center and asset management , Network infrastructure selection 、 Delivery and maintenance . The corresponding physical information that needs to be managed to all network infrastructures , Including the distribution of data center network infrastructure 、 Device configuration information 、 Corresponding manufacturer information 、 equipment IP And other resources , So as to ensure that the construction of the data center can meet the business needs .

Application operation and maintenance is also inseparable from service and resource management , We should always master the responsible business and the relationship between businesses , Business depends on resource relationships , In order to find the fault problem in time and give early warning , Or respond immediately when there is a problem , Arrange relevant personnel to jointly remove obstacles . More Than This , Also manage the equipment resources , Sort out the resources 、 Service bearer , We should allocate and use reasonably , According to the needs of different businesses , Allocate network infrastructure with different configurations , Ensure that resources can be fully utilized . And constantly check points in daily work , Find the problem , Timely tracing , Eliminate hidden dangers .

Similarly, operation and maintenance research and development 、 Database operation and maintenance 、 Operation and maintenance security related work is based on network infrastructure , There is no physical infrastructure to rely on , All the above will become empty talk .

thus it can be seen , The management of network infrastructure can be called one of the priorities of operation and maintenance . This paper will focus on this part of work , Talking about “ My hand ”、“ A good hand ” And “ Vulgar hand ”.

present situation --“ My hand ” Operation and maintenance  

At present, most data centers choose excel Table combination CAD Drawing 、 Record network infrastructure resources by manually recording data , such “ Manual recording ” Management style , We can call it “ My hand ”. however “ My hand ” The operation of also exposes some problems , For example, there is a large amount of equipment 、 Resource information has a wide range of dimensions 、 High turnover of personnel , If you want to realize the fine management of the physical layer of network infrastructure , It is bound to cost a lot of labor , Finally, it leads to over reliance on senior operation and maintenance engineers 、 The cost of labor time is huge 、 Different recording methods 、 Word of mouth data and other issues . 

Then for operation and maintenance management , Is there any “ A good hand ” Well ？ Reduce equipment failure to a greater extent , More precise guarantee for key businesses , More timely alarm when fault is found . The answer is yes , With the development of data center industry , Although our management method can barely meet the management needs , But its cost is high , If there are intelligent means involved in the optimization of management , So can it be more efficient 、 Quickly realize operation and maintenance management , We can call it “ A good hand ”.

How to achieve “ A good hand ” Operation and maintenance

Now there is access to network management software for active equipment status management ,“ A good hand ” The real problem to be solved is the management of passive equipment and information in all dimensions of assets , Optimize the existing operation and maintenance mode , For example, how to reduce equipment failure ? How to quickly record the equipment termination information ？ How to quickly remove obstacles 、 Guarantee work to achieve data support ？ How to make full use of network infrastructure resources 、 Reasonable optimization ？ How to ensure the safe and stable operation of business , Realization “ More secure 、 More accurate 、 More timely ” The goal of .

I think professional management tools and network management software can be used to complement each other , The implementation is based on the physical layer , Combined with logical layer management , Physics + Walk with logical legs , Record the original in excel Asset information on the form , It is displayed on the network infrastructure management platform in the form of visualization , Manage by intelligent means , So as to reduce faults , Improve system safety and reliability , More accurate obstacle removal , The efficiency is greatly improved .

About operation and maintenance work and nVisual

nVisual It is such a process that takes the daily operation and maintenance management process of the operation and maintenance department as the core , Take event tracking as the main line , To solve the problem IT Eight management problems in operation and maintenance management （ Event management 、 Problem management 、 Change management 、 Maintenance Management 、 fault management 、 Site configuration management 、 Equipment life cycle management 、 Emergency management 、 Quality management 、 Cost management and safety management ）, Provide an efficient 、 Standardized network infrastructure management platform . It can not only meet the daily needs of operation and maintenance work for network infrastructure resource management , And by email 、 Prompt the responsible person in the form of SMS , To standardize the operation and maintenance workflow , Improve the service response efficiency of system maintenance . 

With PDCA Realize network infrastructure system management in a circular way

• ​P ( plan  PLAN) : From the definition of the problem to the action plan

• D ( The implementation of  DO) : Implement the action plan

• C ( Check  CHECK) : Evaluate the results

• ​A ( Handle  ACT) : Standardization and further promotion

First use the network infrastructure management platform to complete the resources according to the needs （ Occupied position 、 Occupy equipment 、 Occupy cables, etc ） Distribute （ plan ）, Inform the implementation personnel in the form of work order to implement as planned , The implementation of system calibration after implementation , Finally, the next step of allocation is carried out according to the implementation .

nVisual It can not only assist the daily business on the shelves, but also through information integration , Realize the comprehensive management of various resources , Including various static resources 、 basic data 、 Effective management of spare parts resources .

How can we not call it “ A good hand ” Well ？

About “ Vulgar hand ” Thinking

Last , Let's talk about the current operation and maintenance work “ Vulgar hand ”, In fact, the pain point problem of physical layer management of network infrastructure has always existed , Many units have also thought of introducing intelligent means , Try to reduce the pressure of operation and maintenance , But choosing does mean adding hardware , Such as electronic distribution frame . At present, the construction of data centers in China has developed to a certain scale , There is a large volume of old data centers , Adding hardware equipment is bound to interrupt business , And because the electronic distribution frame needs double configuration , In the data center, it is equivalent to adding a failure point , It only realizes the management of the direct link connection relationship of the equipment , For the process 、 event 、 Historical faults 、 Change information 、 Publish the information 、 Operation of the 、 Knowledge record 、 Comprehensive analysis and other aspects are still lack of control , Finally, the construction cost is increased , Is this kind of management self defeating “ Vulgar hand ” Well , It is worth discussing .

Conclusion

I hope every operation and maintenance engineer can find his own “ A good hand ”, Provide... For the enterprise “ More secure 、 More accurate 、 More timely ” The operation and maintenance services of .
