Absolutely - connecting clients to an Isilon cluster via multiple protocols is supported.  OneFS 7.x supports NFSv3 and v4 concurrently, as well as several other protocols - SMBv1, SMBv2.0, SMBv2.1, HDFSv1, HDFSv2 (OneFS 7.0.2 and above), RAN (RESTful Access to Namespace - 7.0.2 and above), and FTP to name a few.  In my experience, seeing roughly 100 Isilon customers every quarter, it is very rare where a customer will use just one protocol to connect to OneFS and utilize the filesystem.  Nearly always, multiple protocols are in use simultaneously.  Hope that helps Cheers Rob
I', m sure the name says it all OneFS. But is there any way to have NFS3 and NFS4 clints on the same cluster? I have googled read support and as many of the white papers I can but no definitive answer :-( Appreciate any feedback. OneFS 7.0
NFS3 and NFS4 concurrently?
