The demand for storage capacity to record video surveillance image is growing at an unprecedented rate driven by increasing high resolution cameras and longer data retention polices. In recent years, video surveillance has shifted from analogue to digital data archiving; which recording streams via digital video recorder (DVR) or network video recorder (NVR) to external storages with RAID features data protection. Furthermore, critical record would request infrastructure like storage area network (SAN) to achieve performance, scalability and reliability. Arena offers a complete range of DAS, SAN solutions to meet the critical requirement of modern video surveillance application, various features are tailored for it and various configurations can fulfil different demand.

Feature Highlight

AV Streaming for Video Performance
Video surveillance application present a very different data workload to IT based application. The Recording data is transmitted sequentially from cameras to the DVR/NVR, and playback data request from users to DVR/NVR is very few and randomly. The AV-streaming function handled by intelligent cache-control is tailored for Video surveillance application; which optimize the sequential write video performance and allowing DVR/NVR to manage more cameras.

Data Security and Reliability
Recording Data are protected through various RAID Level (0,1,3,5,6) to prevent for multiple simultaneous disk failures. The redundant components including power supplies, fans and controllers that insure the 24x7 non-interrupt operation for critical application. Advanced disk maintenance features like Disk-Self-Test, Disk Scrubbing and Disk Clone could detect and correct disk failure in advance.

Hot Swappable RAID Group
The Disk Group (DG) can be portable as a removable media. The DG offload function is default; without any software or special drivers support. With an easy command, designed RAID group would be able to hot swap while system is still on, then move to off-site storage system. This tailored function allows playing back historical data requested by off-site users without interrupting any on-line surveillance activity.

Easy Configuration and Management
The user friendly interface delivers easy configuration and monitoring through LCD indicator on the front panel and/or web-based GUI management. Active notification will be delivered automatically from configured SNMP/SMTP or through MSN if any special events occurred.

Green Design
Eco friendly features like automatic disk spin-down while system in idle mode, automatic smart FAN control and high-efficiency power supply, help saving power consumption, and reducing carbon footprint.
