Anyone seen numbers yet on iSCSI performance? I'd be especially interested in talking to anyone using Exchange and iSCSI together. Steve Evans SDSU Foundation

NDMPcopy and fibre disk shelve file copy.
by Ngoh, Clarence 01 Aug '03

01 Aug '03

Hello good toaster folks We are planning to move a huge lot of data (> 3.0 T) from our 32 GB drives to 144 GB. I am carrying out some preliminary information about the quickest path to move the data across - the first option is to use ndmpcopy and the second is to copy it from shelf to shelf over fiber. Since this is a preliminary investigation, can someone please point me to relevant resources that may be helpful? I am after statistics of transfer rates between the two and perhaps other materials that others have found useful. I have googled and looked through past toaster archives, and most of it is either outdated or lack of relevant information. Thanks. Clarence. ************** IMPORTANT MESSAGE ************** This e-mail message is intended only for the addressee(s) and contains information which may be confidential.

We currently have several SQL 2000 Servers accessing databases and logs on an F720 via CIFS. It works very well. We've not used the VLD option but do plan to implement it for Exchange by the end of the year. We'll probably use CIFS for as long as MS supports it for our SQL databases. As far as performance goes, we saw a small performance hit with our SQL databases primarily because of the way that our volume is layed out.

As you can see this is not ideal, but in this configuration, our SQL Servers still perform remarkably well. By the way, we are going to separate our volumes eventually so that SQL has it's own set of disks. My recommendation would be to set your filer up with it's own SQL volume if at all possible.

RE: Does anyone have experience with SQL 2000 on NetApp?
by Reinoud Reynders 01 Aug '03

We use SQL and VLD just one year now. We are very happy with it. The performance is very high. We use a separate volume for our logs. So we have 1 volume for the data with several QTREE's (one for every database) and 1 volume for the logs. This is because there is a difference between write/read behaviour (logs = write; data = read). The performance is much better when you split logs and data. Of course, more disks in your raidgroup gives more performance (5 spindles of 72 GB disks for data). For the logs, we use just 2 spindles, but that is no problem. We use that volumes only for VLD. We have some other volumes on the same filer for other applications (file server, ...). When you want more details, please contact me.

Performance impact of 6.3 to 6.4 upgrade?
by Davin Milun 01 Aug '03

01 Aug '03

Does anyone have any concrete experience with what the performance impact of the WAFL reorg that upgrading from 6.3.x to 6.4.x causes is? I have some very loaded (almost disk bound) 960C's running 6.3.2, which I need to upgrade to 6.4.1 (because I'm told that the new DS14 Mk2 shelves that we're adding are not supported by 6.3.x). And I'm worried about the performance impact of the upgrade is: how much disk/CPU increase it uses while it runs, and how long the reorg typically takes. I've asked the same question of NetApp support, but I was wondering if anyone here has some personal experience. Thanks! Davin. -- Davin Milun E-mail: milun(a)cse.buffalo.edu

SNMP and VIFS
by paul.winchcombe＠ukgateway.net 01 Aug '03

01 Aug '03

Hi all, This is my first posting so apologies if I get syntax wrong. I have a 940c cluster and have setup 3 network card in a multi VIF and then a Single VIF. When I unplug a cable from the config I get a message on the console e11a down but the SNMP message sent to the Management Station was TRAP 4. The mib has been loaded and traps for machine being rebooted and Volume full are decoded correctly. What am i doing wrong ? Regards Paul

Aside from Netapp themselves and ebay does anyone have any vendors they can recommend to purchase new replacement parts for my F740 and F760. All I really need is disks. Thanks Dan
