Cluster Storage

        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 cluster backup function stores multiple copies of a single video within the cluster storage system; supports internal cluster backup and multiple-cluster 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.

           RAID Optimization

    • Supports RAID 0, 1, 3, 5, 6, 10, 50.
    • Instant application of RAID mode; supports dynamic online expansion of logical volume.

        Green & Energy-efficient

    • CPU dynamically adjusts operating frequency according to workload.
    • Intelligent fan speed adjustment; higher heat dissipation efficiency and lower noise.
    • High quality power supply to increase power conversion efficiency and reduce power loss.

        Compatible & Open

    • Provides complete API interfaces for third-party cluster storage system connection.
    • Supports standard ONVIF access.
    • Supports Smart IPC access.

        Software Module

    • Cluster Video Access (CVA): Recording task management, recording service and device status management, etc.
    • Cluster Video Storage (CVS): Video data read/write operation
