Great question. (BTW, SMB and CIFS are often used interchangably by Microsoft. Their definitive protocol specs (MS-CIFS, MS-SMB, and MS-SMB2) sanction interchangable usage. I haven't read MS-SMB3.) > Please see > http://blogs.technet.com/b/josebda/archive/2013/10/02/windows-server-2012-r2-which-version-of-the-smb-protocol-smb-1-0-smb-2-0-smb-2-1-smb-3-0-or-smb-3-02-you-are-using.aspx > for further details on versions and history. > Please also take a look at > http://blog.fosketts.net/2012/05/06/smb-3-huge-scope-impact/ for > Stephen Foskett's take on SMB 3.0 (Stephen is a storage expert, > independent blogger, and runs Storage Field Day as a part of his > Tech Field Day series...) > Facts, not FUD, please. I'm merely reporting my own experience on a large heterogenous net with actual servers and clients using these protocols in production. In the right environment with the right clients and servers, SMB 3 probably rocks. However, I was responding to a comment (which you trimmed) about CIFS performance in general, which I expanded on. The Foskett article cited (I happen to be a Foskett fan) has a lot of superlatives, was written prior to the product release, and appears to be based entirely on product claims -- not observed performance. He could be right, but I wouldn't call my observations FUD, especially not while referencing Foskett's hype! > (note that the above does not speak to the OP's original q on > NFS on Win2012R2, and suggestions to consider SMB instead - just > trying to make the point that SMB is a performant proto vs. NFS > these days...) _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
