Tim,
It has been our experience that even if there are multiple network connections on the server, when it makes an NFS connection to the NetApp, it will only use one of those connections. We are not using NFS4/PNFS. Is Oracle NFS basically PNFS?
We had a process (non-Oracle) on a system a few years ago. We tried giving it an nfs mounted file system. The transactions drove the filers in the dirt. We switched the to FC luns and set up a "local" file system on the server. It is much easier on the filers and faster than the nfs file system. We're concerned that using NFS of any type may cause this issue again.
Unfortunately we probably won't find out if it is too abusive until they run full steam. At that point stopping them and changing the process probably won't be very popular :-)
How do you do your backups/DR for your nfs file systems?
Thanks,
Jeff

Personally, I would strongly encourage you to not use iSCSI.
Instead, look at using Oracle's NFS implementation. It is fairly easy to setup. Give it a bunch of network adapters on the host (like two or three) and point at the NetApp.
The client will use all the connections Oracle knows about and performance can really scream, especially if you can use 10GigE

Greetings,
My Oracle experience with and without NetApp has largely been non-existent. Please bear with me on this. All of our current DBs are on dedicated servers with locally attached storage.
One of our groups has a 6280 cluster running 8.1.2P4 7-mode. They want to look into using iscsi to a new 11.2 Oracle server. The cluster can get pretty busy at times so I'm not sure Oracle NFS will work in this case.
The questions are largely about backups and DR. I'm curious about how most people choose to back this up and how to recover for that solution. I know there are lun copy options, snapmanager/flex clone options, etc. We're very open to manual scripting and custom solutions. Backups would most likely go to a NearStore, and the DR would be a second server connected via iscsi also.
Thanks,
Jeff
