   I'm not Dick, but will respond anyway. We use a Netapp for our test system and it works fine for that. My experience has been that it is quite dependent on your network configuration (dedicated 100baseT as minimum), and multiple simultaneous reads and writes seems to bog it down. I would not use it for production datafiles expecting a heavy load, but archivelogs might be okay.

Dick ... did you have problems with Netapps on your archivelogs or

         just the datafiles or both??

 We are considering using it for alternative archivelog solution...

Last place we were at ....we did have a few issue with datafiles but it got worked out and worked fine after that.

Rahul,

    We're heading out onto the SAN route as well from the external storage world. Right now we use a number of HP-UX servers connected to one of two EMC
symmetrix arrays for datafiles and one of two NetApp Filers for archive redo logs. They work well, but the EMC's are expensive and every now and then, like
last year, you end up with a "forklift" upgrade. The NetApps are cheaper and
are suppose to work for Oracle datafiles, but we've had a myriad of problems getting it to work. The idea of a SAN is that the actual disks can come from a
number of vendors and the SAN implementation handles the differences so that you
& I only see available disk space. And from Oracle's point of view all of the
disks are local, not remote or NFS mounted or NAS or any of that other weird stuff out there. I would not classify it as much as a cost, but flexibility issue.
