Product Limitations

The number of file system instances that can be created by a single account is limited to 100.

The file system supports NFSv4.0, NFSv3, and SMB protocols via TCP
Currently, the maximum purchase capacity for capacity models is 100TB, and for performance models, it is 20TB. Please contact technical support for more space
The maximum size of a single file is limited to 1TB
The number of inodes in a single file system is limited to 100000000
The number of file system instances that can be mounted in a single cloud host is not limited
The number of hosts allowed to mount a single file system is not limited
The number of mount points for a single file system is limited to 5. Please note that this is not the limitation on the number of hosts that can mount the file system, as long as the host is within the VPC allowed by the mount point, they can access the specified file system
The throughput of a single capacity-type file system grows as the capacity increases, with a single TB throughput of 120Mbps and a limit of 20Gbps
The performance-type single file system has a throughput limit of 10Gbps during public beta testing, please contact technical support for higher throughput
The file system currently only supports expansion operations and does not support shrinking operations
The NFSv4 protocol file system supports cross-account and cross-regional access based on VPC
