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.
