I run some CIFS sessions, probably not enough to judge performance vs. a server / LUN config but there's two reasons why I limit my CIFS services - Group Policies and security. NetApp CIFS doesn't support GPO's and Kerberos security.

This may not pose an issue in your environment but we use GPO's to secure certain areas of our servers and deploy software so we can only use it for a limited set of circumstances.

Another side-effect I've noticed is that it seems that any changes made to a CIFS session requires the CIFS service to be restarted. But with my limited exposure to CIFS, there may be some work-a-rounds I'm not familiar with.

Good luck,

John.

Here's the story... Lately I've been getting a lot of requests for CIFS services on my filer. Until recently I have been able to avoid a lot of windows interaction but that time is coming close to an end.

Does anyone have any major issues with CIFS, does it kill CPU and how reliable is it in general? Basically I'm looking for an overall feeling. The reason I ask is I'm unimpressed with the HTTP daemon built into the filer and I'm not confident in it's abilities to do other things besides NFS without personal experience with it.
