Digital video surveillance involves the collection, storage, and use of vast amounts of data. Therefore, a high-performance video surveillance system must have a high-performance data storage system, which is related to data management efficiency, data security and data utilization efficiency. Then, in the telecom-level digital monitoring system, the requirements of the data storage system generally have to meet the requirements of six aspects.
One of the key features of telecom-grade digital surveillance systems is the large concentration of data storage and decentralized front-end applications. Therefore, the storage system must have strong data transmission capabilities, otherwise it will affect the efficiency of data storage and utilization.
The characteristics of massive data storage requirements and rapid growth changes require storage systems to meet the massive storage requirements for telecom-level data monitoring. At the same time, they must have good scalability and cope with the rapid growth of data volume for storage space expansion.
In addition, since the monitoring system generally requires real-time video input, this real-time video input puts high demands on the data writing capability of the disk array. Otherwise, if the writing speed is not up to the requirement, the data is largely concentrated in the cache. Will eventually cause the cached data to overflow and the host will crash.
At present, the surveillance video needs to delete the data after a period of time. After the data is deleted, there will be a certain time interval, and the data cannot be written immediately. At this time, the data is stored in the cache, and the larger cache can guarantee more. The data is stuck in the cache, waiting to rewrite to the hard disk space.
In addition, for the telecommunications-grade system, good stability is necessary. If it lacks stability, it will cause great trouble to many users and even bring huge losses.
Carrier-class storage requirements determine the need for good storage management. Simple and orderly management can help users reduce the cost of operation and maintenance, and it is also an important guarantee for system stability.
