Hi Tracy,

I'm the Product Managers for CIFS at Network Appliance and I would like to reinforce that NetApp is NOT removing the "Mixed Mode" security style. NetApp will continue to provide the same three security styles in ONTAP that it always has -- These being UNIX, NTFS and MIXED.

In the majority of cases the use of MIXED is not needed to solve most multiprotocol usage scenarios Recommendations like this are generally documented in publicly available Technical Reports like this: http://www.netapp.com/library/tr/3014.pdf http://www.netapp.com/library/tr/3014.pdf

Now, it is possible your concern on dl-toasters may have stemmed from a student who attended a recent NetApp training class and may have been confused between Mixed Mode Security (i.e. CIFS and NFS) vs. MIXED CFMODE in Fibre Channel. The instructor may have made a statement along the lines of MIXED mode is not recommended by NetApp and may be going away in the future. The instructor was talking about MIXED CFMODE (ala FCP.) Apparently, it is not recommended, STANDBY and PARTNER are and SINGE_IMAGE CFMODE will replace PARTNER and MIXED CFMODES on future platforms. It may have been that one of students got confused and thought the instructor was talking about MIXED SECURITY MODE ala CIFS and NFS when in fact it was the CFMODE for FCP.

Sorry for the confusion and let me know if you have further questions.

Thank You.

Does anyone know the future of the security mode -- "mixed mode"? Several co-workers returned from NetApp training stating that this particular mode is not encouraged and may be dropped in the not too distant future from NetApp support.

Has anyone else heard this or can confirm this to any degree? We are about to set up a new Filer and I'm trying to decide what to do with a volume that is currently configured for mixed mode security on an old Filer. If anyone has experiences changes from mixed mode to either all CIFS or NFS, I'd appreciate their inputs as well.

Thanks. Tracy
