function characteristics

• High reliability system design

Redundant design of key components in the system, modular drawer style structural design to enhance system reliability;

Based on clustering technology, load balancing between storage nodes, mutual backup, and automatic service adjustment without interruption in case of multiple node failures;

Support intelligent re recording of network disconnection, video recording and transmission after network recovery to ensure data integrity;

The system uses cloud backup function to store the same video data multiple times on internal devices of the cloud storage system, supporting both cloud backup and multi cloud backup.

• High performance application services

Based on discrete storage technology, multiple devices can provide concurrent and fast response data reading services, which can meet the needs of massive data retrieval in seconds and high-speed data download;

Based on virtualization technology, all storage node spaces are virtualized into unified available resources, which can be accessed by users through interfaces. Space resources can be flexibly divided, and video recording space supports dynamic expansion and contraction without data loss;

A single device can meet the concurrent writing of hundreds of videos;

Support video frame analysis, provide keyframe query and playback functions for the system;

Support frame extraction and storage of video streams;

Support image search.

• Low cost system construction

Supports mixed storage of videos and images, and can be directly written to storage devices without the need for streaming media servers or image servers;

Support streaming media forwarding services, which can save forwarding servers.

• Efficient operation and maintenance services

Having a comprehensive maintenance mechanism and providing maintenance tools;

Support monitoring of the operating status of hardware such as CPU, memory, network card, disk, etc;

Support active alarm for software and hardware system failures;

Support active alarm for device failure and disconnection.

• Easy to expand

Linear growth in storage capacity and performance can be achieved through stacking or cascading, with service interruptions during the expansion process, making it easy to achieve rapid expansion from tens of TB to hundreds of PB.

• Disk detection, repair, and RAID optimization technology

Disk detection and repair

Provide pre check technology for disks before use, ensuring prevention before use;

Provide inspection techniques for disk usage to ensure timely alerting;

Provide repair and recovery techniques for disk failures to improve disk efficiency.

RAID optimization technology

Supports multiple RAID modes including 0, 1, 3, 5, 6, 10, and 50;

Supports RAID build and use, and supports dynamic online expansion of logical volumes.

• Green and energy-saving

CPU intelligent frequency modulation

Dynamically adjust the frequency of the CPU based on its utilization to reduce system power consumption.
Fan precision intelligent speed regulation
Provide intelligent and refined speed regulation strategies to effectively improve heat dissipation efficiency and reduce noise.

Hard disk intelligent sleep mode
Based on the workload of the business, some or all of the unread/writable hard drives can be put into sleep mode to reduce energy waste and extend the lifespan of the hard drives.

Efficient power supply

Adopting efficient power supply to improve power conversion efficiency and reduce energy loss.

• Compatible and open
