Cloud storage: Eradicating fragmentation challenges

At present, video surveillance is moving toward high-definition direction, at the same time, in the video surveillance network driven by the video surveillance business into the data blowout era. And the arrival of large data, to a great extent, the test of video surveillance storage technology. The concept of cloud storage and intelligent storage is deepened.

Storage technologies for monitoring experience the development of a single tape, disk, disk array, and storage network system. The important inflection point of storage intelligence is the advent of disk array raid. In Ip-san, storage becomes a stand-alone computer system, including devices, software, and networks, with the intelligence to address interoperability, scalability, technology upgrades, component availability, and data security, especially for data backup, recovery, scaling, and disaster preparedness.

In the period of networking and digitalization, different storage solutions have been taken according to the project scale. For example, in a small-scale video surveillance system, Low-cost DVR storage becomes the mainstream, while in the centralized video surveillance system of multi-level network, SAN storage is the mainstream. These two kinds of schemes overcome some shortcomings of tape storage by solving the problem of digitalization. On the other hand, these two programmes still have some aspects that need to be optimized. such as DVR storage, its lack of reliability security such as RAID is a nearly fatal flaw; centralized SAN storage has always been optimized for price/performance, and storage costs have become the biggest pressure on video surveillance systems in the early days of expensive general-purpose fc-san.

In the face of a large number of data and application requirements in video surveillance system, networked storage technology has found new applications. The future of video monitoring back-end equipment development direction, in addition to cloud storage, the concept of intelligent storage is deepening.

Cloud storage technology to completely resolve risk and fragmentation issues

Virtualization is one of the main features of cloud storage. Storage Domain International Authority SNIa (Storage Network Industry Association) gives the definition of storage virtualization (Storagevirtualization): "By abstracting, hiding, or isolating the internal functions of the storage System/subsystem from applications, compute servers, network resources, Implement storage and data management independent of applications and networks. Storage virtualization technology is to abstract the underlying storage devices unified management, to the server layer to mask the specificity of storage equipment hardware, but only to retain their unified logic characteristics, so as to achieve a centralized storage system, unified and convenient management.

Compared with traditional virtualized storage, virtualized storage technology based on "raw data Block" inherits not only the characteristics of "high disk utilization" and "management convenience", but also solves the risk and fragmentation problem of file system completely.

Traditional storage technology disk utilization is generally only 30-70%, and the use of virtualization technology disk utilization up to 95%, storage flexibility, can adapt to different vendors, different classes of heterogeneous storage platforms, for storage resource management provides greater flexibility.
