Product Advantages
  • 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. The throughput can be calculated as follows: 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 4 PB in just one click.

  • Secure

    Access to file systems is secure and under permission control. VPC-based user authentication isolates user data.
