About 6 months ago on OTN there was an article discussing an implimentation of
Oracle using a NetApp servers using NFS mounts. The implementation was using a
modified NFS client done by VA Linux. There was some 500 databases running
with the datafiles residing on the NetApp. I wouldn't typically put a datafile
on a NFS mount, but after reading this I felt a little more comfortable with
trying this out. Since then, I have tried this out on a HPUX-11 system running
8.1.6 EE, and have had no problems with it.. even had a hard lockup on the
Netapp and all was well after restarting the netapp and database server.
