Oracle over NFS is a very viable option. Now that there are scalable NFS solutoins based on cluster file systems (eg, Hewlett Packard EFS Cluster Gateway), you can scale out NFS performance in the exactly the same way that Oracle scales out RAC. Multiple nodes can access shared storage concurrently, and failover is completely transparent. So there's no reason, going forward, that Oracle over NFs can't be as fast or faster than block level protocols and even more fault tolerant. Here's a list of the currently OSCP certified Oracle-over-NFS solution providers, including NetApps: http://www.oracle.com/technology/deploy/availability/htdocs/vendors.html -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Max Sent: Monday, January 30, 2006 4:59 PM To: genec00(a)comcast.net Cc: toasters(a)mathworks.com; 'Peter D.

You can generally run Oracle No problem over NFS.

There is no really good general rule to apply to the situation here. These days customers should be able to chose a single box that supports whatever interconnect and data protocol they're used to using. IF the DBA's are crusty, old guys they'll probably insist on a block level transport. And Netapp makes a *great* SAN/NAS combo.

That's because the Sun NAS Gateway does not run Solaris, it runs a proprietary and not well-adopted "storage-optimized" OS They got from Procomm. So all the work Sun has done on v4 has been, of course, on Solaris. Since v4 is not just a few extra bells And whistles on v3, but a whole new on-the-wire protocol, stateful instead of stateless, it is a lot of work to write an NFS v4 server from scratch for Your own weird OS...though most of these so-called NAS OS's are just some variant of FreeBSD with a different file system.

You can always have your crusty DBA contact Oracle and see what they use. Most likely it is NetApp Storage with NFS. I have several customers running Oracle with NFS, and there are still those that insist on FCP with the possibility of converting them to iSCSI on the QA side.

Replacing our NetApp
by Stewart, John 31 Jan '06

It's time for us to upgrade our backup hardware (currently a DLT7k library), replace our Oracle DB storage hardware (now direct-attached), and our NetApp F740. We're looking hard at a Sun SAN solution. Part of it would be to replace the NetApp with a Sun 5310 NAS Gateway: http://www.sun.com/storage/5000/5300/5310gateway/index.xml Our NetApps over the years have been so reliable that I am very leery to replace them with a new vendor's hardware. However, going to a SAN at all doesn't really make sense unless we include the NetApp data (about .6 TB now) in the SAN. Does anyone have any experience with this product? It seems to have all of the basic stuff that we need (NFS, CIFS, snapshots, etc). Are there any questions in particular that we should be asking? thanks johnS

iSCSI to NetApp
by David Lee 30 Jan '06

30 Jan '06

(System: ONTAP 6.5.5) We have a Windows 2003 server (SP1) which uses iSCSI to mount a drive onto a NetApps filer. When transfering files the performance is very poor: it can take 5 minutes to transfer a 350 Mbyte file. Looking at Performance Monitor on Windows while a file transfer is taking place shows that Disk Queue Length readings can reach: Average=94, Maximum=2142 We are using a QLogic QLA4010 Host Bus Adapter with the latest firmware (3.0.0.4) and driver (2.1.0.8). Any ideas? Thanks in advance. -- : David Lee I.T.
