SFS supports the NFSv3 protocol only. The default export options are rw, no_root_squash, no_all_squash, and sync.
To obtain better performance, you are advised to use the operating systems listed in Supported Operating Systems, which have passed the compatibility test.
Currently, SFS does not support replication.
Currently, SFS does not support cross-region access.
SFS Capacity-Oriented does not apply to file storage scenarios requiring low latency and high IOPS, such as database services, website building, and code storage.

SFS Capacity-Oriented can be accessed only on the intranet and used only on the cloud.

Currently, NFSv3 protocol is supported (NFSv4 is not supported).
A maximum of 10,000 compute nodes can be mounted to and access a single file system at the same time.
The maximum capacity of a single file system is 2 PB, and that of a single file is 240 TB.
Multi-VPC access is supported. You can add a maximum of 20 VPCs for one file system and create a maximum of 400 ACL rules for all added VPCs.

Only the NFSv3 protocol is supported (NFSv4 is not supported).
A maximum of 500 compute nodes can be mounted to and access a single file system at the same time.
The maximum capacity of a single file system is 32 TB, and the maximum capacity of a single file is 16 TB.
Maximum number of files supported by a single file system = Capacity/16 KB. For example, the maximum number of files supported by a 500 GB file system is 32,768,000 (500 GB/16 KB = 500 x 1024 x 1024/16).
By default, a single directory contains a maximum of 2 million files.
The maximum full path is 1024 bytes, and the maximum file name length is 255 bytes.
The maximum soft link length is 1024 bytes.
The maximum number of hard links is 255.
The maximum directory depth is 100 layers.
