Limitations and Constraints

General

• SFS Capacity-Oriented supports the NFSv3 and CIFS protocols. Export options with NFSv3 include rw, no_root_squash, no_all_squash, and sync. Export options with CIFS include rw and sync.
• Encrypted CIFS file systems do not support copychunk.
• You can mount file systems to all ECSs that support the NFSv3 protocol. To obtain better performance, you are advised to use the operating systems listed in Supported Operating Systems, which have passed the compatibility test.
• To obtain better performance, you are advised to use the operating systems listed in Supported Operating Systems, which have passed the compatibility test.
• CIFS file systems cannot be mounted to Linux servers.
• Currently, SFS does not support replication.
• Currently, SFS does not support cross-region access.

SFS Capacity-Oriented

• Only NFSv3 is supported (NFSv4 is not supported), and CIFS is supported (SMB 2.0, 2.1, and 3.0 are supported, but SMB 1.0 is not supported).
• A file system can use either the NFS or CIFS protocol. It cannot use both protocols.
• 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 4 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.
