Hi Glen,

When it comes to NAS, yes, 11g is the best so far. However, 10g on NAS is a good match as well–just not as good. It always goes like that, right? Oracle9i requires a lot of patches for NAS so that is a bit more work and honestly, if you have a 9i database running, just keep it where it is as long as it works.

What I don’t recommend is running old Linux distros for Oracle over NFS. Stay with the 2.6 Kernels.

And like the front page of my blog states, these are MY opinions, not Oracle’s so please folks, don’t drum up a list of Metalink notes showing Oracle over NFS tips with RHAS 2.1 with Oracle9i and stuff like that. All technology information is time relevant.

Does that mean you don’t recommend a NAS unless running 11g? Where does 10gR2 fit into the NAS picture?

Kevin,

What type of savings are we looking at in comparison to doing storage on a FC SAN? Also, what type of replication capabilities are available in the event I want to copy data from one NAS device to another at a DR site (non-oracle and Oracle related without having to use Data Guard).

Richard,

Two words: Storage Grid.

Very cool! Now all they need to do is update their download links so that people can actually check it out…

I am actually a little disappointed in the way that everything is heading from a grid standpoint, though. What would be very cool is a tighter integration between RAC concepts and ASM auto-balancing, to the point that Oracle would support a true shared-nothing system. In a lot of ways, it seems like they’re very close.

When we can get to the point that I can deploy some nice machines with a fast chunk of directly-attached disk (as well as the option to use network-attached disk), and just tell ASM which volumes to use and have it handle data-sharing between machines (ideally with a tie-in to the DB itself, so that frequently read data that wasn’t updated often would be replicated on all the nodes (space permitting), whereas frequently updated data would only be in two places, et cetera)… that will be a wonderful day. And scaling will simply be plugging in more disk, more servers, or both.

In theory, of course.
