As the World Expo, the manufacturers have introduced their own security products. So popular in today's security monitoring, storage into place as a video, can keep up with the high-capacity security video walking? Its Technology Can guarantee the security and integrity of the video you? In fact, the answer is yes: can.
First, security storage technology for the mass storage needs. Monitoring data is 7 × 24 hours to write, storage time from 7 days, 15 days ...... even to 1 year, the amount of data increases with time linearly. For a Safe City Project, the overall control of large ones are usually a few thousand to tens of thousands of roads, thousands of TB more common items, which the traditional storage industry is unimaginable.
Second, the performance requirements. Video Surveillance Main video stream write, characterization performance of the storage to support the number of road stream (usually 384Kbps-2Mbps). Written in multiple concurrent cases, bandwidth, data capacity, cache and others have great influence on a lot of pressure on storage, storage needs at this time specifically for optimized video performance.
Third, the price of security sensitive storage technology. Security Monitoring mass storage industry, as total capacity, causing the price of the total costs. Anti-speaking, the capacity of the unit cost (price per TB) is very demanding;
Fourth, centralized management requirements. Security monitoring applications, due to the need a large number of storage devices, mass data storage device, must be effective management up to the end user to use to provide convenient, reliable and transparent support.
Finally, the network requirements. TCP / IP network is a network security monitoring technology to develop in the direction of the network infrastructure, based on TCP / IP network storage technology will be in the process of network security monitoring technology to play an irreplaceable role.
Application based on the above understanding, memory gives us a conclusion to be learned: the area of security control may be moving in two major areas of storage technology development, a node is not too large for small applications, NVR is the future the main direction of development; followed by large-scale Monitoring System , Video management platform + SAN storage (to ISCSI storage based) is still the choice for large-scale monitoring system.
Video surveillance storage architecture On the video surveillance network storage system to Ji, application storage device is a novel, with media management and specialized software applications, high performance storage devices. Compared with the normal storage, application storage addition to the basic data storage and security protection features, it also has network management, media asset management, video transcoding, video on demand and shared storage management functions.
Hardware parameters: due to storage in embedded applications, storage applications are generally based on PC architecture NAS or ISCSI storage devices. Storage devices in terms of hardware features a fully redundant, hot-swappable hardware architecture and modular design approach to support dual controller, dual Power supply Dual fan module, eliminating single points of failure, always ensure the stability and reliability of storage systems.
Cluster function: a distributed load balancing Cluster structure to support multiple controller nodes. Front-end Host Port multi-channel dynamic load balancing, support for automatic failover. Controller can achieve the cluster, all Active mode of operation, and failure can automatically failover. Back-end disk can be extended online, the data can be automatically uniform in all ports after the disk or storage device to improve performance of a single volume access.
Storage virtualization: the data to a flexible strip-type distribution of a cluster in each disk node, to create a single, shared storage pool, to meet Enterprise Increasing storage requirements and application requirements, users can effectively save the initial investment, maximize investment returns.
Automatic load balancing technology: When the new controller node and the new storage device to join the cluster, the use of automatic load-balancing technology to the load at the same time, evenly distributed on all nodes in the cluster, to avoid bottlenecks in production, achieve full use of storage space to play their best performance, do not need to machine down time.
