DS-A72XX-CVS Storage System
Features and Functions
High Reliability Design
 Redundancy design for key parts; modular drawer design.
 Cluster-based technology to implement load balance and backup among storage nodes.
 Supports automatic network replenishment (ANR) to restore videos during network disconnection.
 The cloud backup function stores multiple copies of a single video within the cloud storage system; supports internal cloud backup and multiple-cloud backup.
High Performance Application
 Based on discrete storage technology, multiple devices are able to respond simultaneously to data read/write services, finish massive data search at second level, and download data at high speed.
 Based on virtualization technology, all storage nodes are virtualized as a unified resource which is accessible through specified port; storage space can be flexibility divided and can be adjust dynamically without data loss.
 A single device can respond to the concurrent writing requests of several hundred video channels.
 Supports frame analysis and offers key frame search and playback.
 Supports video stream frame extraction storage.
Cost-efficient System
 Supports direct video storage. No stream media server is required.
 Supports stream forwarding. No media switch server is required.
Efficient Maintenance Service
 Complete maintenance system, with provided maintenance tools.
 Operating status monitoring for CPU, memory, NIC and HDD.
 Active alarm for software and hardware failures.
 Active alarm for device failure and disconnection.
High Scalability
 Increase storage space and performance by stacking and cascading without interrupting services. Easily and quickly expand your storage capacity at TB or even PB level.
HDD Detection
 Pre-detection before using HDD.
 In-process detection when using HDD.
 Restoration and recovery technology after HDD failure.
