Hi, I was wondering if anyone has had any experience with using the Dfs functionality within Samba. I've been searching for any performance information and or documentation regarding Dfs in particular load balancing i.e. 1) How does it load balance? Is it some sort of round robin? 2) Is there a limit to the number of servers that can used in the load balance? 3) How many requests per second can Dfs handle? Any information or links would be greatly appreciated. Thanks Nicholas
Hi, I've also an interest in Dfs and plan implementation once I have sufccessfully gone to Samba 3.>1) How does it load balance? Is it some sort of round robin?No, its more like autofs using NFS with sym links in the Unix world. What I mean is that you can spread various data over several unique volumes and have them appear under the same dir structure. This not only simplifies data management in "where are my files again" but it also allows you to spread network and disk i/o over several points. Another advantage is that maintanance can be performend on a particular data location (ie; Raid) without affecting the entire directory or job structure. All this is very old skewl stuff in the Unix world but is kinda new in the Windows world. One thing to keep in mind is that the initial data request goes through the Dfs server in order to establish the mount point or network path but after that, subsequent requests go directly to that server bypassing the Dfs server. As for the rest of your Q's, test and document your results. Bri-
I am not certain how Samba specifically will handle this, but I can say from experience that MS's FRS/DFS implimentation is a dissaster, don't go near it if you value your data. ----- Original Message ----- From: "Nicholas McDowell" <teknik@theorphanage.com> To: <samba@lists.samba.org> Sent: Wednesday, October 29, 2003 5:28 PM Subject: [Samba] Dfs - Load Balancing> Hi, > > I was wondering if anyone has had any experience with using the Dfs > functionality within Samba. > > I've been searching for any performance information and or documentation > regarding Dfs in particular load balancing i.e. > > 1) How does it load balance?

I'm also interested in using DFS but have no previous experience with it. Just what are the issues??? TIA, Marion D.

You can define multiple targets for a DFS link. The client can then pick any of those targets. However, MS-DFS does nothing to make sure those targets are identical. It is up to the administrator to make sure the targets stay synchronized.
