This topic introduces different gateway models and specifications.

File gateways

  • Models and features

    The following table lists the features and scenarios supported by different gateway models.

    Basic Standard Enhanced Advanced
    Archive and storage Not supported Supported Supported Supported
    Express sync Not supported Supported Supported Supported
    Bandwidth 1 Gbit/s 2-2.5 Gbit/s 4.5-5 Gbit/s 10 Gbit/s
    Capacity 64 TB 128 TB 256 TB 256 TB
    Recommended cache disks Ultra disks Ultra disks SSD and Enhanced SSD SSD and Enhanced SSD
    Recommended scenarios Sharing and storage of a small volume of logs and data. Small websites and user-created FTP sites. Sharing and storage of logs and data. Sharing data across multiple regions. Shared directories, user-created FTP sites, small-sized websites, data archives, and data warehouses. Unified storage of data and logs. Archiving of large amounts of data. Data sharing among multiple regions. Medium-sized websites, virtual desktop infrastructure (VDI)-based shared directories, code libraries, and data warehouses. Unified storage of data and logs. Archiving of large amounts of data. Data sharing among multiple regions. Large-sized websites, VDI-based shared directories, code libraries, and data warehouses.
    Recommended number of active clients ≤ 5 ≤ 20 ≤ 50 ≤ 150
  • Features and prices

    The following table lists the specifications of the express sync and remote sync features. Choose the features based on your actual needs.

    Number of files Metadata synchronization rate File change synchronization frequency Monthly cost
    Express sync > 5,000,000 Maximum synchronization rate: 1,000 incremental files per second. Less than one second. The maximum update interval is the refresh interval of the NFS/SMB client cache. Fixed. If the number of API calls is less than 20,000,000, the cost of each month (30 days) is calculated as: (2+0.5 × number of shares) × 30.
    Remote sync < 5,000,000 The synchronization rate depends on the scanning and matching time. More than 15 seconds. The maximum update time is two times of the remote sync interval. Costs are based on the scanning interval and total number of files.

Block gateways

The following table lists the features and scenarios supported by different block gateway models.

Recommended scenarios Large data disks (larger than 32 TB) and data backup volumes Large data disks (larger than 32 TB), SMB volumes, and user-created FTP sites. Large data disks (larger than 32 TB), medium-sized websites, DFS volumes, code libraries, and user-created FTP sites. Large data disks (larger than 32 TB), medium-sized websites, DFS volumes, code libraries, and user-created FTP sites.
