Supply of Hikvision 48 bay disk array DS-A71048R series

FeaturesHigh reliability system designRedundant design of key components in the system, modular drawer structure design, and 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 servicesBased 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 retrieval;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.

Disk detection and repairProvide 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 technologySupports 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 Energy SavingCPU intelligent frequency modulationDynamically adjust the frequency of the CPU based on its utilization to reduce system power consumption.Fan precision intelligent speed regulationProvide intelligent and refined speed regulation strategies to effectively improve heat dissipation efficiency and reduce noise.Hard disk intelligent sleep modeBased 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 supplyAdopting efficient power supply to improve power conversion efficiency and reduce energy loss.Compatible and openCan provide a complete set of API interfaces for integration with third-party cloud storage systems;Support front-end access to standards such as ONVIF and GB/T28181;
