RE: Filer storage for databases, seriously? (Was: Re: NetApp ques tions)
by rdobbins＠netmore.net 09 Aug '00

09 Aug '00

No one thoughout recorded history, apart from assorted nuts, has ever believed that the Earth was flat; Eratosthenes calculated both its circumference to within 1% of the true value as well its tilt relative to the plane of the ecliptic no later than 200 B.C. The only real problem was that of terra incognita - i.e., nobody knew exactly where the landmasses were located until a) someone sailed there, and b) accurate chronometers were developed by John Harrison in the 18th Century, enabling navigators to calculate longitude with a high degree of accuracy, and then relay that information to cartographers. Advances in spherical geometry a la Mercator assisted the latter group, of course. Historical canards aside, let me restate that I'm very interested in hearing about production experience with NetApp filers and Oracle over NFS. I've a 740 with a Gigabit Ethernet interface, plugged into a Catalyst 5509 doing MPLS, and so would be willing to entertain the notion if someone can give me anything beyond benchmarks. I know all about snapshots and all that, by the bye. It's -performance- which is the question. Thanks for the pointer to the link, I'll be sure and check it out. ----------------------------------------------------------- Roland Dobbins <rdobbins(a)netmore.net> // 818.535.5024 voice -----Original Message----- From: Keith Brown [mailto:keith@netapp.com] Sent: Tuesday, August 08, 2000 5:48 PM To: rdobbins(a)netmore.net; Perry.Jiang(a)bmo.com Cc: toasters(a)mathworks.com Subject: Filer storage for databases, seriously?

Beware conventional wisdom Roland. People used to think the Earth was flat too. :-) While I wouldn't be so bold as to *guarantee* performance boosts in utilizing the filer storage approach for every database application under the Sun, the simple fact is that filers contain a myriad of features that are very attractive to the database market, and NetApp now draws a significant and growing portion of its revenues from this space. Snapshots & SnapRestore greatly simplify and enhance database backup and restore environs. The WAFL RAID design puts failure resiliancy into the disk subsystem without forcing you take the performance hits inherent in general purpose RAID-5 designs or going to disk-doubling RAID-1 approaches. SnapMirror gives you database replication to offsite locations for disaster recovery purposes. WAFL's ready expandibility lets you make room for growing databases without disrupting their operation. The list goes on... Oh.. and yes... performance very often gets a shot in the arm too! > I've no empirical data > to back this up, mind you; Don't worry. Nobody ever does, not even our direct-attach competitors, not that they can be too harshly criticized. Meaningful performance comparisons are tricky to architect, usually have a short shelf life, and customers have an understandable tendency not to believe vendor funded benchmarks anyway (due to the fact that the vendor performing and/or funding the benchmark almost always wins!). Nevertheless, we did publish a relatively innocuous one some time ago, which can be viewed here: http://www.netapp.com/tech_library/3044.html > it's just that there's so much overhead > associated with NFS even on an optimized platform > like the NetApp filer, I can't see it as being a win. There are certainly some "swings-and-roundabouts"-type things to consider when looking at the two approaches, and some people do conclude that there is more overhead in the network attach approach, dismissing it offhand. However, as far as performance goes, all the theory in the world is no substitute for the practical experience that could be gained by trying a solution for the application you have and actually bearing witness to how well it works and what it performs like. > If there's anyone out there with Oracle experience on filers > via NFS, either pro or con, I'd love to hear from you. I'm hoping there will be some on this list. As I mentioned, beware conventional wisdom.

NDMPCopy can be handy for this sort of application, however I don't know if someone has ported it to NT yet. It is a freeware utility that runs on the host and controls the filer via NDMP commands.

NetApp questions
by Jiang, Perry 08 Aug '00

08 Aug '00

Hi, there I have a question regarding NetApp Filer 740. Oracle account I am running a Solaris Oracle server, which is a NFS client of the NetApp Filer. Do I have to create an Oracle account on NetApp Filer and put the entry in /vol/vol0/etc/passwd? If yes, what the purpose of that? An on-line NetApp document, "Oracle for UNIX: Integrating with a NetApp Filer", stated that you need to create an Oracle account on Filer. However, according to the System Admin. Guide, /vol/vol0/etc/passwd is only for CIFS, not for NFS. You explaination is appreciated. Perr Jiang

Filer Performance in a CIFS environment
by Mike Hopkins 08 Aug '00

08 Aug '00

I know this is a generalized question where the answer is shaped by a basketful of variables, but I need to start somewhere. I have a Filer 740 that I am using to store files for a Win2000 web server. Pages served up by this combination of hardware are noticeably slower(5 to 10 seconds versus 1 second) than storing the web content on the local drive of the web server. This may not seem like much of a slowdown, but people notice these things and it is a big issue. So, what are some of the things that cause performance hits in a CIFS environment. Any suggestions, war stories, magic potions, or good old fashioned know-how is greatly appreciated. Mike Hopkins Broad Daylight, Inc.

RE: What about SSH

Jay, You are right only the password authentication mode is supported. But I am not sure what I mentioned implied the use of authorized_hosts? Once the session key is generated and encrypted by the client (using the RSA public key of the server), the server receive it and decrypt it using its private key. Then user authentication takes place. Please let me know directly if the use of an authorized_hosts file would work better for your environment. Hope this helps.

Re: Filer Performance in a CIFS environment

Just general suggestions: 1. Are you sure this is a CIFS-only problem ? Check that your network cards are set to 100MBit, Full-duplex on both sides, or better yet, move to gigabit... 2. Why not buy an HTTP license and use the filer as the web server itself ? 3. To the point - check your filer OnTAP version - there were many CIFS changes lately as I know - maybe performance also... 4. Be more explicit - give us your "sysstat", "sysconfig -r". You can also run from rc_toggle_basic "statit -b", then after some web pages flowing around, do "statit -e" into a file. You will be able to see disk activity there and see if it's the filer's "behinds". Check also for network errors in "netstat".

If the default raid group is increased the current and subsequent groups ONLY can be added to. As raid groups build themselves as they are required, then by default once raid group 3 is started raid group 2 is assumed to be complete. > See 4).

Don't have experience with that, but I can think of a siggestion: In you antivir script: rsh toaster0 options cifs.show_snapshot off <your antivirus part> rsh toaster0 options cifs.show_snapshot on This will hide the ~snapshot during antivirus check.

Jim, We're currently using NAV5 to do this however, we're having to move to Corp. Edition 7.02 because of Windoze 2000, so I'm looking for another command line driven virus scanner that I can use. On a side note, what are you using to exclude snapshots. My efforts to put ~snapshot in the exclusions have been futile.

Jim -----Original Message----- From: Nail, Larry Sent: Friday, August 04, 2000 2:53 PM To: 'toasters(a)mathworks.com' Subject: Virus Scanning Just curious if anyone is running a virus scanner against filers for CIFS? ______________________________________ Lawrence D.

move command on filer?
by Nick.Mayrath＠envoy.com 04 Aug '00

04 Aug '00

This weekend I need to move alot of files around of my F720. Is there any "move" command locally on the filer that I can use instead of using my NT machine? My concern is that using the NT machine will cause the moves to take longer since they have to "pass through" my NT box. Thanks
