NAS storage NFS vs. iSCSI

Hi,
I´m currently thinking about how to make use of a NetApp NAS Filer with Oracle EE 10r2 in a non-RAC environment. I see two ways for connecting it and several ways to make use of it.

Connecting:
NFS - the traditional way using NFS V3
iSCSI - block oriented protocol - appears at the server as a local disk

Usage NFS:
Just a mount point to the local filesystem

Usage iSCSI:
a. install oracle on top of a traditional filesystem like LVM´s vxfs b. RAW usage with ASM

Is there a preferred way recommended by Oracle?

The database will be a OLTP-DB sized around 30 GB. We are going to attach the filer through the production LAN. Would it be an issue not to use an iSAN?

What should be considered additionally?
I know of a NetApp´s product SnapValidator which supports Oracle´s HARD technology to prevent data corruption. Would I need that product using either NFS or iSCSI?

Thanks in advance
