[ Huaqiang Security Network News ] Storage virtualization in video surveillance has some basic requirements in the infrastructure. So, how does video surveillance implement storage virtualization? 
First, there needs to be a strong dedicated storage network where data information can be stored in any possible free space on the network and accessed without affecting application performance. Therefore, it is more suitable for projects with large capacity and relatively concentrated distribution. For example, the storage architecture of some large-scale safe city projects can use storage virtualization. The security city project involves more compatibility requirements between new and old storage devices. Virtual storage and high-speed network can solve the storage problem of data in heterogeneous storage device environment, save storage space, and avoid adjustment of a large number of application architectures. Program reprogramming and modification. The video recording is saved in the entire storage pool. It does not need to consider the specific storage devices on which the specific storage devices are deployed. It does not need to consider whether the capacity and performance of the specific storage devices meet the application requirements. . A robust storage network guarantees read and write bandwidth requirements for the entire storage pool.
Secondly, virtualized storage needs to cooperate with server virtualization to achieve the best performance of the virtual data center, and the server computing performance is improved very fast. The earliest virtualization technology is aimed at the effective use of computing resources. Video surveillance applications and video recording storage are the relationship between computing and storage. If a device like a video-specific IP-SAN device that combines computing and storage cannot be virtualized, there is no problem with standard PC servers and third-party open network storage virtualization.
Finally, storage virtualization requires IT resource management tools for the overall management of physical devices and virtual devices. Virtual servers, virtual data volumes, etc. need to determine specific locations, paths, performance status, fault status, etc., otherwise effective resources cannot be achieved. Regular maintenance of management and uninterrupted production. Therefore, the application-level management platform must be based on IT infrastructure management tools at the IT infrastructure level.
In fact, under the concept of private cloud, virtualized storage can actually consider applications in the same storage device. Because third-party open storage devices can basically use tiered storage technology, that is, different types of the same storage device configuration. Hard disks such as SSDs, SAS disks, fiber disks, and SATA disks allocate storage for different applications to disks of different speeds. Match the performance detection and resource scheduling tools to properly adjust the hotspot application to achieve automatic balancing of application load and make full use of the performance resources of this device. This video surveillance system at an airport in the west has been applied.
In addition, there is a virtualized storage model that utilizes a large-scale single file system video surveillance system that can scale-out technology. This requires video surveillance applications to be specifically developed and adapted for specific devices to accommodate such storage. use. Such a single file system is stored in its internal data slice, and then mirrored, and then saved in different storage locations to meet the data security requirements, while the application workstation can access the file, the system can be the specific distance of the user Or assemble the slice to form a file for the user to access the path as soon as possible, but this method requires the video surveillance application to re-adjust the architecture and program to match the advantages of the storage device itself. This is based on the video surveillance storage virtualization application method under the public cloud architecture. It is believed that there will be corresponding applications coming soon.
Storage virtualization is not an end but a means. The purpose of video surveillance is to quickly call video real-time monitoring and large-scale storage video surveillance video, as well as the analysis and exploration of large-scale video surveillance video and even historical data accumulation classification and statistics. In this way, the role of security information data can be maximized. Storage virtualization is just a means of optimizing storage, improving storage performance, facilitating management, and improving system availability during implementation. In the system planning and design, we need to consider from the user requirements and application environment in many aspects, remember not to invert the virtualization for virtualization.
