Sybase & Netapps
by Derek Kelly 13 Apr '00

13 Apr '00

Not too long ago I remember seeing someone out there who was planning to store Sybase data on Netapps. I wonder if that person (or others) could share the outcome of this project with the list. We are beginning to jump into this arena and are looking for feasibility and potential pitfall info before we begin. The setup will be data from Compaq Alpha ES40's and/or DS20's with DEC Unix 4.0 running Sybase 11.9.2 through a Cisco Catalyst 6509 to a Netapp F760 with gigabit nic's installed at each end of the pipe. I have seen documentation related to using Oracle in such a fashion, but not much on Sybase. We will be doing the same setup with Oracle so any info in that area will be much appreciated as well. Cheers, Derek Kelly www.genomecorp.com

Quotas: Hard, Soft, and Time limits?
by Timothy Demarest 13 Apr '00

13 Apr '00

Does DOT support soft and hard quotas? How about time limits? From everything I've searched, it looks like it only supports hard limits. Regards, Tim -- Timothy Demarest ArrayComm, Inc. demarest(a)arraycomm.com 2480 N. 1st Street, Suite 200 http://www.arraycomm.com San Jose, CA 95131

F740 Quad card performance
by Laurent Aymeric 13 Apr '00

13 Apr '00

I've a F740 running 5.3.4R3 with a Matrox Quad card connected on a CISCO 5509 (trunking mode) I've create a vif in multi mode. I've selected on my network 4 clients (HP running 10.20) using each a separated port on the quad card thanks to their MAC address (best case). Everybody is 100 Meg Full Duplex configured (no autoneg). The test I run is copying a 100 Mb file from each client to the filer, and the perf I've got are: Hostname: eauze Bytes: 104857600 Elapsed time: 43.281 (043281 msec), KBytes/s = 2365.93 Hostname: mimizan Bytes: 104857600 Elapsed time: 44.328 (044328 msec), KBytes/s = 2310.05 Hostname: orlu Bytes: 104857600 Elapsed time: 40.493 (040493 msec), KBytes/s = 2528.83 Hostname: tarascon Bytes: 104857600 Elapsed time: 41.819 (041819 msec), KBytes/s = 2448.65 The NFS calls/s varies from 200 to 1800 only during the copies. It seems that all the ports "share" a 10 Mb bandwith (peak I reach with a single client test). Can I expect more from such a configuration? PS: We got many "Bus overruns" errors on each interfaces.

RE: Need new backup solution

Hi John We're looking for a way to implement backup of our NetApp (F740) Files in our current NetWorker backup solution (Legato). Are you using ClientPak for NetApp? Or are you just backing up the files via an NFS share? And are you utilizing the snapshot function? And if yes - how?

It works well on the server that's an Ultra 2 with dual 300Mhz CPUs. The other one is slow because it's just a Sparc 20 with Dual CPUs. Haven't had the chance to replace it yet.

Hi Brian, You may also want to take a quick look at a white paper on the external NetApp web page.

What I am looking for is info on how others are backing up 200G volumes on 740's or 760's. I just purchased a pair of 760's and am going to need a nice stable reliable backup system for them.

Implementing Sybase for Linux [ASE 11.9.2] on a NetApp Filer
by Shahryar G. Hashemi 12 Apr '00

12 Apr '00

Greetings, I followed the instructions documented on the NetApp web page [http://www.netapp.com/tech_library/3040.html] on implementing a Sybase ASE server using a NetApp Filer. The system I used was a RedHat 6.1 Linux server [2.2.14 kernel] with 1GB of memory. During the initial installation I received the following error: Building Adaptive Server 'SNOCTEST': Building master device... Task failed Master device: /sybase/syb_1 Buildmaster: Could not lock device "/sybase/syb_1". Server 'SNOCTEST' was not created. I contacted Sybase on this and they stated that it was a NetApp problem. How is it that the file can't be locked when being created? Any ideas?

we use a Breece-Hill Q47 tape library unit and are currently testing Workstation Solutions QR 2.6 -- it looks good. Supports several Unix platforms including Linux, NT. It will also allwo you to back up either from the netapps or to a tape unit/library attached to the netapps using NDMP ...

One way works, one way doesn't
by TTSG 12 Apr '00

Hi, Short time reader, first time poster. A customer of ours recently ordered 2 F720's and snapmirror and had it delivered to us to put up in our co-location. His current setup is 8 BSDI 4.0.1 machines, all on various subnets, into a Cisco 2924 and then some other stuff before it hits our router. So, I put each of the filers on their own subnet too. When I do the mount from the MAIN IP on the box, to the MAIN IP on the filer, life is fair (Tweaking NFS is a priority). The issue I have is since they are on 2 different subnets, the data goes out over the 2924, past the "stuff", to the router, back down the same pipe, past the "stuff" again, to the filer. LOTS of unnecessary traffic. SO, to prevent all the 8 machines currently from wasting bandwdith, they all have a 172.16 private network IP with a 255.255.0.0 subnet (Machine 1 is 172.16.100.1, Machine 2 is 172.16.101.1, etc). I put an alias on the e0 of 172.16.120.1 . However, when I mount it, it just doesn't work. Any "oh yea, you can't do that idiot" or other comments, or ways to figure out whats happening? Thanks, Tuc/TTSG

HSM and Netapps
by Graham C. Knight 12 Apr '00

12 Apr '00

Has anyone sucessfully used a fairly large HSM solution with Netapp based storage? Any suggestions for the best product to use? We have ~20 filers in a mixed Unix/NT environment. Veritas tells us that their product won't work with netapps. That was a bit surprising. Anyone know otherwise? Thx, Graham
