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/writeoperation
