Table 5-1  Relationship between the FTP feature and other features




File systems can be shared using multiple protocols. In multi-protocol sharing mode, a file in a file system cannot be written concurrently. When sharing a file system using multiple protocols, you are advised to configure read-write sharing for one protocol and read-only sharing for other protocols.

A file in a file system that written concurrently in multi-protocol sharing mode will cause data loss, exercise caution when using it.

Impact on System Performance

File systems can be shared in NFS, CIFS, FTP, and HTTP modes at the same time. When clients concurrently access a file system based on different protocols, the overall performance slightly decreases.
