For the data center, the importance of operation and maintenance work is self-evident. Operation and maintenance management is the longest phase in the data center life cycle. The work of the operation and maintenance of the data center is mainly to systematically plan, organize, coordinate and control the management objects of the data center, which is the general name of the management work related to the information system service, including the maintenance of the environmental infrastructure of the computer room, system and data maintenance, the use of management tools, personnel management and so on. For the data center with huge investment, in order to get a return as soon as possible, we need to make more efforts on the operation and maintenance work, and do not enter the bad operation of "first-class equipment, second-class design, third-class operation and maintenance". The work of high-quality data center operation and maintenance is very important. So how to improve the operation and maintenance level of the data center, this paper puts forward four magic weapons to win the data center operation and maintenance work. Doing a good job in these four aspects will keep the data center running in the best state and create the greatest benefit for the data center.

Magic weapon 1: engineering documents

Documentation is very important to the work of data center operation and maintenance. Including the installation, configuration, optimization, networking, equipment interconnection and other aspects of the data center, through these documents, you can know the operation of the data center like the back of your hand, and quickly troubleshoot and find the fault point when a failure occurs. Another important function of the document is the inheritance of the work. When someone leaves, he only needs to leave the work document, and it is easy for others to hand over the work. There is also the accumulation of work experience documents. Although various data centers are more or less the same, they basically dominate the world by server, network and storage, but each data center has its own style, advantages and disadvantages. Through the data center operation and maintenance output of a variety of technical documents, will provide convenience for future generations, and can improve the overall operation and maintenance capacity of the data center. There are a variety of documents in the data center, and you don't know when which of them will come in handy. According to past experience, data center documents mainly focus on three categories: first, data center internal architecture documents, such as networking introduction, equipment interconnection, IP distribution, air conditioning system, electromechanical system, wiring system, etc. Second, data center management documents, such as: computer room management system, computer room duty and handover system, computer room inspection system, equipment operation standard system, security protection system and so on. The third is to transform the data center and optimize the engineering documents. For example: upgrade instructions, network change plans, emergency measures guidance, software fallback programs, and so on. The fourth is the experience document of data center operation and maintenance. For example: network outage problem analysis, existing computer room environment assessment, if the business does not lose packets, and so on. With these documents, even if a newcomer does data center maintenance, you can get started quickly. In fact, this is true not only for the data center industry, any other industry, any job, to develop the good habit of outputting documents, to provide convenience for themselves and others, can greatly improve work efficiency.

Magic weapon 2: business backup

The business of the data center requires continuous operation 24 hours a year, but it is impossible for the data center to fail without a single failure, and even some data centers perform various failures almost every day. In a data center with hundreds of thousands of devices, it is normal to break a server or a port every day, which requires us to back up our data business. Everything from server to network to storage to data center requires backup, including software backup and hardware backup. Through backup, when there is a problem with the operation of the data center, the business can be adjusted in time to ensure that there is no interruption or short-term interruption. Today's data centers can back up multiple data centers for each other, and even if one of the data centers crashes, the business can be smoothly taken over by other data centers and continue to operate normally, so as long as it is not the end of the world, building multiple data centers in different places can ensure the long-term steady operation of the data center business. Business backup is a huge systematic project, which involves all aspects. There are some backup technologies in any link. It is impossible to deploy backup technology anywhere in the data center, which will make the cost of the data center too high and the design too complex. But it is absolutely impossible without backup, so we need to find a balance between the two. In any case, business backup is indispensable in the data center.

Magic weapon 3: on-line monitoring

The operation of the data center is dynamic and changes all the time. We can not predict what sudden failures will occur in the future, even if there is a backup in every link, we also need monitoring means to ensure that the business is switched to normal equipment. It is essential for online monitoring of data centers. Online monitoring includes network management monitoring, server running status monitoring, air conditioning system monitoring, computer room environment monitoring and so on. When an anomaly is found, even if the alarm is notified to the operation and maintenance personnel, or the software automatically enables the backup system, ensure that the data center continues to operate stably. Online monitoring is the guarantee to ensure the fault-free operation of the data center. Effective online monitoring can reduce the impact on the business when the data center failure occurs.

Magic weapon 4: periodic inspection

As the saying goes, "prevention before it happens" is indispensable for the daily periodic inspection of the data center. Through periodic inspection, some hidden dangers of operation can be found in time, and then eliminated, which can greatly reduce the possibility of serious failure in the data center. Periodic inspection can include inspection of all kinds of equipment, inspection of environment, inspection of power supply and air-conditioning equipment, filling in daily inspection record form, maintenance record, operation table and so on. Through the comprehensive analysis of the previously recorded data, once some data have fluctuations or anomalies, effective measures should be taken in time to avoid hidden dangers leading to failures. Through periodic inspection, we can also have a comprehensive understanding of the entire data center. Once we need to carry out system transformation or capacity expansion and other work, with the previous inspection data reference, the transformation or expansion plan will be more targeted. Do not think that periodic inspection is only to record the basic parameters of some equipment operation, through these parameters you can see the operation status of the entire data center. For a novice who is just engaged in operation and maintenance, through periodic inspection, you can quickly understand all aspects of the data center and carry out maintenance work independently.

Engineering documents, business backup, online monitoring and periodic inspection are the four important aspects of the operation and maintenance of the data center. Only by doing a good job in these four aspects can the data center maintain long-term stable operation and produce good benefits. It is the main embodiment of the level of operation and maintenance of the data center. With these four magic weapons, the data center will benefit for life. Technical exchange plus Qbot 451114649
