macOS supports three network protocols: AFP, SMB, and NFS. There is some support for FTP in macOS, but that is out of scope for this document.
AFP is unsupported by PowerScale, and since macOS 10.9, AFP is not the default file-sharing protocol for macOS. As such, it is not covered in this document.
Historically, NFS was the protocol of choice for connecting macOS systems to PowerScale. NFS is no longer the best choice for macOS. Testing described in this paper concluded that SMB is as performant, and often more performant, than NFS on macOS.
SMB is the protocol of choice for macOS clients connecting to PowerScale storage. This paper shows that SMB consistently outperformed NFS on macOS, and describes additional topics:
