Re: Vol copy max speed ? alternatives ?
by FPS France 02 Jul '01

02 Jul '01

FPS France Just to let everyone interested in know : - we firstly would make the migration with snapmirror but we figured out that migrating 14x18Gb disks to 7x36Gb disk was impossible (a 13x18G volume - with one 18G spare beside - is tiny larger than a 6x36G volume - just 9G greater :) - so we used ndmp through tapes because we were not sure enought of the NdmpCopy reliability - may I find a tool to validate NdmpCopy in our lab ? :) - when the migration was successful, we installed Snapmirror and obtain a throughput of 20Mb/s :) systems were 5.3.7R3 and models, two F740. Thank you for all your mail.

I think this is a close English translation (thanks to Altavista's babelfish service) In English: Me I saw SnapMirror making of the 55 MB/s between two F840 via Gigabit. But I do not have experience with of F630 I think that SnapMirror is the best solution in any event. I think that SnapMirror can " be rented " for a migration... Call me if you wish to discuss it.

(on a F630 Filer :) Reasons given by the NetApp support is the CPU has a bunch of work in calculating optimizations of read and write operations. But I would be sure we are really not strunglled by any other limitations. So here are our two questions : - (just to be sure) did anyone succed in using the vol copy command once and go beyond these limits ? -what is your opinion about that alternative : plug the Filer on a private Giga-ethernet network and make a manual copy (copy -R mnt/nac/vol0 /other_place ) of the whole volume from a shelf to the other. Do you think we could obtain real high rate transfers while keeping the integrity of the volume ? (the volume is a root volume with the "/etc" directory), no special tricks needed (if I use Windows, may I expect ACL modifications) ? I thank you in advance.

MSSQL on NetApp System
by Lori Gartner 30 Jun '01

30 Jun '01

We are considering the purchase of a NetApp filer for our SAP system. Our SAP system is running on NT with MSSQL 7.0 database. I am told by NetApp that this is no problem - a great solution! I am told by almost every other NAS (and SAN) solution provider that Microsoft will not support me and that I should put in a SAN system and definitely NOT a NAS system. I would really like to hear from someone who is running MSSQL on a NetApp filer! Thanks in advance! Lori Gartner PS - I can not search the archives on the web because our firewall is blocking port 1999. I apologize if this has been discussed before.

Hi - Not sure who is around to read your message at Netapp before the holiday, but if there is anyone that knows a better answer, please pass it along. grepping through what ndmp is passing by default to dump reveals: dump.java: default_env.put("NO_ACLS", "N"); dump.java: default_env.put("EXTRACT_ACL", "Y"); So I'd assume you could flip these, not that I've personally tried it. -dave -----Original Message----- From: Jeffrey Krueger To: ndmp-users(a)netapp.com; toasters(a)mathworks.com Sent: 6/29/01 4:38 PM Subject: NDMPcopy without security Does anyone know of an NDMP environment variable or other method to prevent NDMPcopy from restoring UNIX permissions or NTFS ACL's? We would like to migrate some data by first doing a full copy *with* ACL's, then substitute local group SID's on the destination, and finally resume incremental updates *without* updating our already "fixed" destination ACL's. The benefit of this approach is that SID substitution across a large qtree/volume could take a long period of time (hours/days). We'd rather do that pre-cutover when users are not impacted the during the actual migration when we make the source data read-only or inaccessible. Any ideas?

Anybody know where I can get a replacement faceplate and/or drive-bay cover for a F330? Even a yellow one off a 220 would work; just wanting something other than the tan/putty one on this preproduction/internal unit. bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

F85 Vs 740
by Dion, Mark D 29 Jun '01

29 Jun '01

I'm a NetApp newbie looking for feedback from experience users of these boxes. I just ordered a F85, but because of non availability of F85's was offered a 740 instead. I'm not as concerned w/ scalability as I am w/ performance. The data that it will host is under a 100GB now and should grow much beyond 200GB. The F85 that I ordered has 12 36GB drives which I figure will leave me w/ ~280GB of usable space. There are 120 NT 4 workstations and a handful of UNIX boxes on this network. The majority of the data will be CIFS, some NFS and HTTP. I plan on moving all of the users home folders and shared data to the filer. The connectivity of the servers and filer will be at 100Mb and the workstations are at 10Mb. Any feedback would be appreciated. Mark

F760 Cluster question when using ATM
by David Lockwood 29 Jun '01

29 Jun '01

I am trying to work out how to configure an F760 cluster and appear to be running out of slots. The main connection from the user community to the filer heads is via ATM, for a cluster I am told I need 2 ATM cards for each head in an active passive configuration, the passive connection taking on the identity of the 'failed' (heaven forbid) filer. Now, due to the number of disks required for data storage I need two FCAL loops per filer, 4 required in each head for failover. I need 1x 100Mbit ethernet connection to connect directly to a second cluster for mirroring and 2x 100Mbit direct connections to Unix servers for Oracle database access. The F760 has 9 slots. I can use slots as follows: Slot 1 Quad (or dual ethernet) Slots 2 and 3 for ATM Slots 4,6,7 for FCAL cards Slot 8 for Cluster Card Slot 9 for NVRAM It appears I cannot use Slot 5 for any type of card other than a connection to a tape device! Can I fail the ATM connection over to a 100Mbit ethernet slot, if I use a quad ethernet card then there would be a connection free. This would free up Slot 3 for the fourth FCAL card. Does anyone have any ideas on this and how we can get it all to fit. Before anyone suggests it the answer is no I cannot look at the 840's just yet!
