Has anyone done any benchmarks to compare performance of ASM using RAW
partitions vs. NFS (especially NFS on Netapp)?

A Netapp 3070 is coming my way in about a month so I can't do any
testing ahead of time but wondering what anyone else could share.

NFS mount will likely be a bit slower than ASM on RAW but there is more
to the equation than that.

NetApp's NFS has no issues with respect to device persistence.

NetApp's NFS is essentially plug-and-play. Total configuration time
should be an hour or two.

Fewer moving parts.

That said ... which is the better choice depends on what you are going
to do with it.

- but there is no mention of directio mount options, just wondering
what other options I should use aside from those mentioned in the
Oracle documentation.

Thanks

That is an option to use ASM on a NAS, it is required if you use RAC
standard edition, otherwise it
makes no much sense.

thanks - the configuration would be for 10g enterprise edition,
probably 3 node RAC. I'm trying to get an idea how much performance
loss there is using NFS vs. RAW. thanks

I second that recommendation. Kevin and K.Gopalakrishnan are the guys
with the most profound RAC knowledge of all people I know, with the
possible exception of Scott Heisey, no longer active in the Oracle world.
Scott Heisey and Scott Gosset were the best Oracle instructors that I've
ever known.
