Monitoring disk array knowledge

To define the concept of a disk array is a simple task, because the concept has formed a consensus - DiskArray is a hard disk controller to control the interconnection of multiple hard disks, so that the read and write synchronization of multiple hard disks Technology that reduces errors and increases efficiency and reliability. Disk arrays are a highly specialized and highly reliable product.

So what is a professional disk array? Professional disk arrays have the following signature features: (1) modular design, including cooling system, power supply system, data processing core system; (2) controller architecture can provide redundant controller configuration; (3) Disaster recovery technology such as snapshot, volume mirroring, and remote replication; (4) using independent hardware chips to solve raid computing problems; (5) using high-performance cache technology with cache mirroring.

Disk array development and video surveillance market

From the perspective of the development of the entire industry, the choice of high-reliability and stable storage devices is a problem that every solution user and every solution designer must consider. It is also a success or failure of a solution. The key factor.

Professional disk array manufacturers' general business focus is not in the security market, and the understanding of security is not deep enough, so it is unlikely to directly enter the single-handedly; second is the price dilemma. In the security market, the budget is still relatively tight, and most of them have to be invested in the front-end construction, and the lack of attention to data security has led to a serious shortage of storage equipment procurement budgets, and it is impossible to purchase high-end professional products.

Large application monitoring system

In general, large-scale monitoring systems can reach more than 1,000 points. The most typical case is Safe City. The biggest feature of this type of application is that the system is large, complex, and has a large amount of data. Most of them will adopt the strategy of tiered storage and central centralized backup. The performance and stability requirements of data storage devices are more strict, and the security of the monitoring center is more secure. Concerned, therefore, the disk array system will be used to solve the network bottleneck caused by large data throughput.

Analysis of the application status of storage products in the security video field

With the rapid development of the security industry, people are paying more and more attention to the storage and security of data. Compared with financial data storage, medical center data storage, Internet center business data storage and other fields, the security market is not at the forefront of all data security considerations. Many projects only require storage and basic security. It does not consider the subsequent requirements of fault recovery, data backup, etc. Once a failure occurs, it is extremely difficult to ensure data security. However, with the development of high-definition video technology and the overall cost of high-definition projects, HD applications are becoming more and more widespread, and people will inevitably pay attention to data security.
