Hi Chris, thanks for your quick answer. - autonegotiation and duplex are fine, no errors reported on the switches - pure TCP/IP is fast (like http, ftp etc.) - the Win95 and NT 4.0 which are slow to NetApps are fast to NT fileservers alfred chris(a)webtop.com wrote: > > In toasters(a)mathworks.com, you wrote: > >Any ideas where we might start looking ?

Are there any special considerations on using F740 with VMS? I tried once to mount NFS mount on VMS, there vas no problems, but VMS seems to create some other files. Any experience? _____________________________ Uros Lampret _____________________________

Re: NFS client performance

We had a very similar situation when we first connected an F760 to HP-UX 10.20. Performance was very poor initially, after some investigation we found that having no (0) biods running we got much better performance. This can be changed on HP-UX (10.20 or 11.00) by changing NUM_NFSIOD in the /etc/rc.config.d/nfsconf file. Nobody could tell me exactly how the system was working with no biod processes but it does. >>> "Rick Hulsey" <RHULSEY(a)wnco.com> 09/27/00 02:01pm >>> We have a couple of HP-UX 11.0 systems running Oracle 8i (8.1.6). Each of these systems has about 10-15 small to medium sized Oracle databases on the system. In order to separate tables, logs, and archives for availability and recovery in the event of a filer volume failure, we are using 3 volumes per database. We are using qtrees allow for the mounting the database tables, logs, and archives separately which allows us to use failover between the HP servers for each database. This all boils down to needing 45+ NFS mounts per client.

Well according to Netapp solution id 3.0.2639783.2627617, you should actually _reduce_ the number of biods. There's no reference to a particular version of HP-UX, so I presume it applies to everything. Maybe ;-) --h _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Difference in resources?
by TTSG 26 Sep '00

26 Sep '00

Hi, We've had great luck with BSDI and our F720's, so we decided to spec it for a Sun customer. There are 2 machines.. Thor and Sif. Thor is an Ultra 1, 170E running 5.5.1, pretty patched up. Sif is an Ultra 1, 170E running 5.7, pretty patched up. Both systems currently have 2 Multi-pack 12's with 10 disks in each. The systems serve a single web site, DNS load balanced which is usually decent (LB sales people need not apply, customer doesn't want it). We loaded the content onto the F720, and unmounted ALL the disks of Thor, and told it to use the Filer. Immediately the load rose on the box, and infact has gotten as bad as : last pid: 1040; load averages: 48.67, 35.91, 22.98 18:04:24 315 processes: 251 sleeping, 63 running, 1 on cpu CPU states: 0.0% idle, 28.8% user, 71.2% kernel, 0.0% iowait, 0.0% swap Memory: 497M real, 142M free, 175M swap, 1235M free swap PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 777 www 34 0 2544K 1896K run 0:01 0.22% 1.65% httpd 1030 karupspc 24 0 3232K 2880K run 0:00 0.22% 1.65% ttsgvalidate.c 556 www 34 0 2568K 1936K sleep 0:02 0.20% 1.53% httpd 494 www 34 0 2544K 1896K run 0:01 0.20% 1.53% httpd 618 www 34 0 2544K 1896K sleep 0:02 0.18% 1.40% httpd 800 www 34 0 2544K 1896K sleep 0:01 0.18% 1.40% httpd 762 www 34 0 2552K 1904K sleep 0:00 0.18% 1.40% httpd 926 www 34 0 2544K 1904K run 0:00 0.17% 1.27% httpd While at the same time : last pid: 8293; load averages: 1.02, 1.51, 1.59 18:04:57 312 processes: 310 sleeping, 1 zombie, 1 on cpu CPU states: 55.5% idle, 11.4% user, 22.7% kernel, 10.4% iowait, 0.0% swap Memory: 512M real, 7888K free, 139M swap in use, 1268M swap free PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 8292 root 1 50 0 2384K 1648K cpu 0:00 1.51% top 7903 www 1 58 0 2712K 1856K sleep 0:01 0.79% httpd 8176 www 1 58 0 2696K 1840K sleep 0:00 0.77% httpd 8005 www 1 58 0 2688K 1824K sleep 0:00 0.44% httpd 7838 www 1 58 0 2688K 1816K sleep 0:01 0.43% httpd 8002 www 1 58 0 2712K 1856K sleep 0:00 0.42% httpd 8071 www 1 48 0 2688K 1824K sleep 0:00 0.34% httpd 8066 www 1 49 0 2688K 1824K sleep 0:00 0.34% httpd 8092 www 1 58 0 2712K 1856K sleep 0:00 0.33% httpd Sif was doing that..... Is this expected? ALOT more kernel usage, a LOT higher load average. It ebbs and flow, but it hasn't gotten below 5 since we started. 5 didn't bother me. Almost 50 does. On BSDI, I know I have a daemon called NFSIOD : Nfsiod runs on an NFS client machine to service asynchronous I/O requests to its server. It improves performance but is not required for correct operation. I did notice quite an improvement. Is there anything I need to do on the Sun or Filer to get better performance? Any ideas why I might have degraded the performance so bad? Thanks, Tuc/TTSG

Bruce, I called it "folklore" because I was told about the supposed improvement in disk scrub speed by a couple of Netapp engineers at a recent engineering meeting I attended. Maybe it would have been better to say "from unofficial sources, in a casual conversation, sharing afternoon drinks at a Netapp event". The reconstruct speed is set at the default of 4. The 2 systems are very lightly loaded from a user traffic standpoint, cpu load at under 10% during reads and bursting to 20% during WAFL writes. There are 5 minute periods every 30 minutes when the cpu goes up to 95% during SnapMirror operations. Until there is considerably more user traffic on the F840's, I will not be able to ascertain user impact. My main comment was about the total time to do the scrub. Of course, time isn't the key factor - impact on user file activity would be much more relevant, and I don't have numbers for that yet. -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Monday, September 25, 2000 6:36 PM To: Sam Schorr; 'Todd C.

I would really like to hear where you heard that you cannot snapmirror or vol copy between 5.3.6H1 and 5.3.6. This should work just fine and we do different variations of this internally to netapp. Please let me know where you heard this so that I can find out why this rumor started and hopefully stop it from being propagated.

tar against netapp NFS exported FS reports ACL errors?
by Herbert Kornfeld 26 Sep '00

26 Sep '00

I'm running HP-UX 11 and mounting a handful of filesystems ovber NFS v3 from a filer. This is fine. The only fly in the ointment is that when I use tar to backup a small set of files, I get error messages like these: "optional ACL entries for </foo/bar/baz> not dumped" I understand that I can avoid these messages with the A switch to tar, but I don't understand what these ACLs are, how tar knows they're there and how they got set. I certainly haven't set any extra ACLs up -- I'm relying purely on the native rwx type permissions here. Can anyone enlighten me? --herb end _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Edit /etc/rc to match 840 slot configuration. Swap heads. Boot to 5.3.6H1 floppies. Select normal boot. Install 5.3.6H1 as normal (tar or exe) Download etc. Shouldn't take more than 20 minutes. -----Original Message----- From: Todd C.

RE: ontap 6.0 only 350 cif-sessions?
by Bagg, Rod 25 Sep '00

25 Sep '00

We have identified bug 30873 which can impact CIFS performance in ONTAP 6.0 when the number of active CIFS sessions on a filer exceeds 200. Symptoms of the problem can be client session disconnects, hangs or very poor CIFS performance. A 'cifs stat' would typically show the counter named 'Max pBlk Exhaust' to be a very high number - 100,000s or more. We have identified the root cause of this problem and have developed the fix which is currently undergoing QA and load testing. ONTAP release 6.0R1 is tentatively scheduled to be released by the end of this week to resolve this bug. You can view the online bug report on the NOW site at: http://now.netapp.com/NOW/cgi-bin/bugfind.on?bugs=30873&rels= On this same link, you can click on "Bug Watcher" to be automatically notified when the bug fix has been released.

F840
by Jeff Stampes 25 Sep '00

25 Sep '00

Okay, now that the press release is out, and we all know the technical specs of the 840, what I want to know is: Who's using one? Is the throughput as good as the specs show? C'mon, spill it. We've got one on order, and will put it through it's paces as soon as we get it. We use it specifically for multi-client compilation of our software. I through around 20 Solaris systems (mmostly Ultra80's and Ultra60's), a dozen or so HPC3000 systems and a dozen or so NT boxes at it to compile all three platforms we support, and we currently are stressing out our 760. I'll let y'all know what i find. -Jeff

i don't see any benefit for doing it this way. you can use a seperate gigabit-connection from nt-box to the toaster. then use the "net use" command or say to frontpage to use "\\toaster\inetpub". so you have near the performance of a san and the toaster as your storage. new -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Mark D Simmons Sent: Montag, 25.

If a SAN can offer this it must be possible? I've informally mentioned that the same thing would be very nice on Unix too, both in the distant, and recent past. Currently I manage no filers so I cannot really RFE this. As a concept it's in serious conflict with the appliance philosphy. However, I think the benefits to some users might even justify their stumping up cash separately to buy it.. -- -Mark ... an Englishman in Derby ...

Presenting Netapp as a location disk
by Richard 24 Sep '00

24 Sep '00

I know this is not really, a question that applies just to Netapp's but at the moment I am looking at a SAN that allows the shared remote disk array to be seen by a NT system as if it is a local disk drive (this helps make frontpage happy). And I am trying to find a way to do this with a Netapp as a remote filestore, surly someone has written a NTFS filesystem driver for NT that reads from a network drive, but presents itself as a local drive? If a SAN can offer this it must be possible? Richard richard(a)gits.co.uk
