Care still needs to be taken with configuration as you would any time you are splitting the files of a particular application across platforms, but putting all the datastores for a particular database instance on the filer for any given RDBMS should work fine. As has already been mentioned, we here at Network Appliance talk to our Sybase database over NFS with stores on the filer and have done so for quite some time without problems. It is rumored that Sybase pulled back from allowing NFS access to its data but I have not been able to confirm this yet. We can say (empiracally at least) that it works. The real answer to your question is that we have had some introductory discussions with Sybase and will continue to work with them to gain their certification. You can be of assistance in this by mentioning to your Sybase representatives of your interest in getting your Sybase stores onto the filer. This is precisely how the intial interest was generated at Oracle when a very large Oracle customer indicated that Oracle really should support storage on a filer. I believe that similar interest expressed to Sybase will generate similar support. At the very least, if you have a test Sybase environment, I would give it a try. You will not be able to operate in "raw" Sybase mode, of course, but should still see similar if not increased performance over the network. Bruce Clarke

Ah... well, I don't think the Oracle deal is going to allow Oracle "native filesystem" (i.e. raw) either. It's just so that Oracle will now let their stuff run over NFS if it's the filer. Or is there more to it than that? Bruce

I am the technical contact in NetApp Marketing responsible for the Oracle relationship. The software that officially supports Oracle will be the 4.3 release of OnTap. This software goes to external Beta test this week and should be generally available by the middle of October. The changes to support Oracle were small but very relevant and will be documented in an upcoming whitepaper describing the correct configurations for NFS, Oracle, and OnTap to ensure maximum performance and reliability when storing Oracle database files. This paper will be available in October. Many customers have chosen to already run Oracle without these specific changes and have been having no problems. So I do encourage anyone interested in storing their datastores on a filer to start their testing immediately and to upgrade to OnTap 4.3 before going into production. Any questions feel free to contact me. Bruce Clarke Technical Manager - Business Development Network Appliance, Inc.

Oracle on Netapps
by Brian Tao 28 Sep '97

28 Sep '97

Anyone have some technical information regarding the recent announcement between Netapp and Oracle? Is there a new OnTap (5.0?) that needs to be uploaded on the filers, or is it something that can be done with the 4.x OS? What's special about this Oraclized version of OnTap? http://www.netapp.com/news/level3b/news_rel_970922.html -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

Null ethernet cable and/or private network
by David Drum 25 Sep '97

25 Sep '97

Hello everyone, Sitting here watching perfmeter report network collisions on the machine my NetApp is connected to is making me once again interested in exploring the possibility of setting up a null ethernet, full duplex 100 Mbps ethernet, or private switched ethernet segment connection. If anyone has done this I would appreciate someone setting me off in the right direction. Hardware and software (i.e. informing in.routed to use a particular interface) advice sought. net.karma offered. Regards, David K.

Single vs. dual shelf performance on F230
by Brian Tao 25 Sep '97

25 Sep '97

If I had an F230 with, say, 6 drives, would I see any significant performance gain by placing 3 drives per shelf, rather than having all 6 drives on one shelf (and thus one controller)? This will be for heavily randomized file accesses (e.g., mail or news spool). -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

This will be for >heavily randomized file accesses (e.g., mail or news spool). You might see a minor performance improvement. I think the last time this sort of thing was measured it was reported to be negligible, and didn't really appear until you had 4 or 5 drives on one controller. But this was with different controllers, different drives, etc. so it may no longer apply. It probably can't hurt, and would certainly be worth trying. (Especially with random access... I suppose with a nice layout with good striping, it might be preferable to read it all from one controller at once... not sure how these things are handled at the low level.) Bruce

CIFS and NIS experiences?
by Daniel Quinlan 24 Sep '97

24 Sep '97

We're going to be using CIFS on our filers and I would like to hear about anyone's experiences with CIFS especially using it under NIS. I tried briefly enabling CIFS about a month ago on one of our filers, using NIS, and it worked, but the filer started having problems only a few minutes later, so I disabled CIFS and NIS. The problems were pretty severe ... of the "did someone shut nfs off?" variety, but I didn't have much of a chance to investigate. We are running 4.1d. We're using Solaris boxes as NIS servers. For my next try at CIFS, I'm thinking about not using NIS and just using a text copy of the passwd and group files. Has anyone else tried and/or had problems with CIFS under NIS? -- Daniel Quinlan (at work) Linux, our last best hope for Unix quinlan(a)transmeta.com http://www.pathname.com/~quinlan/
