NVR Manufacture - Cloud Storage NVR

Sysvideo Recently Released Cloud StorageNVR ,It can storage snapshot automatically and video clips manually .







NVR cloud storage solution was a mainstream storage technology

Video surveillance as an important important of proof of time,it’s widely used in  bank,  judiciary, the application and safe cities, and with the development of technology and the needs of the times, there are many places are installing a high-definition camera. The data in these areas need to store time in 1-3 months or six months or more. The arrival of high-definition era, requires not only that the clarity of high-definition camera, but also hhigh-definition picture storage , which is a great challenge for storage technology.

HD monitor storage requirements

According to modern security monitoring storage requirements can be simply summed up as "high five":

High capacity: HD brings storage capacity soared, needs a stable and reliable high-capacity storage: increase the capacity of a single system: extended by cascading multiple SAS JBOD, support 3TB, 4TB hard drives, enhance RAID robustness; using clustered storage systems : Enhanced storage system elastic scalability, reliability compensate for the lack stand-alone
;
High performance: high-definition monitor  has great requirement on storage bandwidth and storage performance to be tuned according to the monitoring features: Performance optimization: stream high-definition big concurrent data streams in different modes (read-write, edge deletion and writing, RAID rebuild) the IO performance optimization, NAS performance optimization; application combining: NVR software is embedded in the application processing power, a reasonable allocation of system resources;

Energy-efficient: Behind the massive storage deployment is a lot of energy consumption, high cost, low power monitoring equipment should be designed: the DVR era, monitor manufacturers to reduce power consumption by hard holiday, extend life, and network storage can use MAID energy savings, but more suitable for a backup archive MAID environment; considering monitoring applications is 7 * 24 uninterrupted, choose high power conversion efficiency (80Plus power supply or DC power supply) is more valuable, can decreased energy consumption on the condition of not affect the application .

High Density: basic security monitoring demand for storage is to reduce the cost per TB, the cost per slot: After the popularity of high-definition monitor, the original 3U16-bay equipment, limited storage capacity of a single, high-bay storage can support more cameras; 4U24 bit more high-density disk storage, each slot can effectively reduce costs, increase the storage capacity of a single, saving rack space;

High Application: Storage must be designed based on actual demand, solving customer pain main concern in order to survive: excessive file fragmentation results in performance degradation, vulnerability of the file system after a power failure, streaming direct writing, efficient indexing structure; improve NVR embedded applications convenience and compatibility, support for Windows / Linux software, provides API interfaces with external monitoring subsystem, to achieve high efficiency analysis, rapid positioning in massive data; in UIT's SV1000G2 example, from product design to run through. "5 high ", using end SAS6Gb technology, Intel latest SandyBridge platform to improve performance, 4U24 / 4U36 high-density design, support 3TB hard drives to increase storage capacity of a single system, reducing the cost per slot; applicable conversion efficiency up 90% of 80Plus power supply, you can save more energy, reduce system operating costs; may be more closely integrated with the monitoring system through architecture optimization.
