QuestionQ13

Cyber security infrastructure and network access

Which of the following statements are accurate about video-security storage?

Choose four
  • A When calculating the number of hard disks required for storage, you need to consider the number of cameras, bit rate, storage duration, storage redundancy, and hard disk RAID.
  • B When video streams are stored in stream forwarding mode, a dedicated server must be configured to forward video streams.
  • C When video streams are stored in direct storage mode, high performance is required for configured services.
  • D Cloud storage eliminates the performance bottlenecks of forwarding and storage servers.
Explanation

Video-storage capacity planning must account for camera quantity, stream bit rate, retention time, and the usable-capacity overhead of redundancy and RAID. Forwarding-mode storage relies on a stream-forwarding server, whereas direct storage requires the configured storage service to handle the stream workload directly. Distributed cloud video storage removes the standalone forwarding and storage servers as individual performance bottlenecks by distributing and scaling those workloads across nodes. Huawei’s direct-stream storage documentation describes built-in streaming services and a fully symmetric clustered architecture with load balancing and service migration.
