Hi

Yes, I know they are files inside a ZF= S. I was speaking from the view from OS. I find it much simpler dealing wit= h LUN instead of NFS Servers, iSCSI itself it's simple to configure. I = dont find any advantage of using dNFS,

In the past I have used 3, 4 = times dNFS (wiithout ASM, I dont see the point of using ASM on top of NFS) = and in a couple I had problems with dNFS multipath Failover, one ended in a= 2 months SR and we finally moved to iSCSI, all problems went away.

Hi,


dNFS is just the transport method, as is iscsi.
From the ZS appliance viewpoint, the luns are files in ZFS volumes

Hi

If iSCSI use as the LUNs as raw disks


If the disks are NFS shares from ZFS then dNFS


Where did you get the information that ZS3 should use dNFS...? Can you = share with us?

Hi All

I=C2=B4m implementing some T5 server with a ZS3 storage.
The disks are shown to the server=C2=A0 as LUNs and then to the ASM= , this configuration works.
But as far as I know the optimal configuration for ZS3 storage is t= o use DNFS
I was wondering two things:
1) if I use DNFS then I must use OS files and skip de ASM or I can/= should/must
use ASM?
2) This is a RAC with two nodes, as far as I know the OCR/Voting can=E2=80=99t be configured as DNFS ( files ) but since I plan to u= se ASM it is posible?

Thanks for any help with this configuration.
