Durable

Fault failover ensures 99.95% service availability and distributed storage with multiple data replicas ensures 99.99999999% availability.

Efficient

File system bandwidth grows as capacity is expanded, providing throughput of 0.02 MB/s x file system capacity (GB) + 100 MB/s.

Easy to Use

File shares can be created within seconds. Storage capacity is available on demand and can be expanded to 10 PB in just one click.

Secure

Access to file systems is secure and controlled by permissions. VPC-based user authentication isolates user data.

Application Scenarios

  • Media Processing

  • File Sharing

  • Content Management and Web Services

Media Processing

Media Processing

Shared file storage facilitates multi-layer HD and 4K video editing, transcoding, composition, and video on demand (VoD).

Advantages

  • High Performance

    Throughput scales as the file system expands, ensuring low latency and interruption-free operations.

  • Low Cost

    Storage can be scaled up or down on demand, and storage resources are charged based on usage.
