RE: CIFS performance Issue

Not sure what version of Data OnTap you are running but have you tried running netdiag to show any lower layer errors. Also, try running sysstat -s 1 to show "real-time" performance stats. We evaluated a FAS880 initially and I think the CIFS protocol is more CPU intensive than NFS and when the CPU >99% we started dropping a lot of packets and saw crappy numbers. -----Original Message----- From: Tim Driggers [mailto:timd@birthdayexpress.com] Sent: Sunday, April 04, 2004 8:58 PM To: 'Jack Lyons'; Tim Driggers; 'NetApp List (E-mail)' Subject: RE: CIFS performance Issue Hi Jack, I am using the same win2k server to copy to/from the NetApp and to/from another Win2k server. The only difference is which interface is used (the Win2k server has 100mbit and GigE to different vlans). I am actually transferring a 30 gigabyte file, not 30 megabyte. Your suggestion to defragment the Win2k box was valid, as the test server was slightly fragmented. I did a quick analysis after the defrag and this is what I found: Win2k server writing 30GB file over a 100mbit link to a Win2k Server: 12.2MB/sec (link saturated) Win2k server reading 30GB file over a 100mbit link from a Win2k Server: 12.13MB/sec (link saturated) Win2k server writing 30GB file over a GigE link to a NetApp 760: 7MB/sec Win2k server reading 30GB file over a GigE link from a NetApp 760: 25MB/sec note: these are the best readings after playing with several Win2k gigE settings (including your suggestion of TCP offload). I guess my question is, should I expect better performance from the NetApp? -----Original Message----- From: Jack Lyons [mailto:jack.lyons@martinagency.com] Sent: Friday, April 02, 2004 9:43 AM To: 'Tim Driggers'; 'NetApp List (E-mail)' Subject: RE: CIFS performance Issue There are a lot of variables involved.

hi everybody, we are using trendmicro to scan our filer for about 8 months now without major issues. the only very annoying thing is that the error message box presented to the client in case of an infection is not customizable. the error message that comes from the trendmicro scanner is really unusable (it´s the complete path to the file which can be very very long) . regards wolfgang > -----Ursprüngliche Nachricht----- > Von: Jack Lyons [mailto:jack.lyons@martinagency.com] > Gesendet: Freitag, 2.

There are a lot of variables involved. What client are you using for copying the file to and from the NetApp. Are you using the Win2k server you are comparing it to?

Hi Jack, We are currently using both vendors. In my view, a mixture of the both allows for coverge, if one of the vendors are a bit slow in reacting and releasing an update to cover a new virus type. The latest offering from Trend allows for one scanner to scan more than one NAS Appliance, which was a restriction that was becomming a pain to live with. I have had not seen McAfee for NetApps in action, but from reading the documentation it behaves in a similar way. Generally we run McAfee on Local client machines and Trend on Servers, and currently we are serving a user base of 5000+ users accross EMEA and have had no problems.

Sergio Hoffmann, 25 y.o. psychotherapist, Germany: I think i'm younkger than main target group of Cialdis consumers, but i have a very hard work, i always had to listen about people's failures, about bad life et cetera. All that problems affected my selxual activity, my wife was not as happy as before with me. I tried Viagras - both genedric and Pfdizer's, but they does not act as good and as long as i want it to be. Finally, my colleague told me about Cialdis and i ordered it. The results were really better, trust a doctor. I'd recommend it to anybody with erectlion troubles. P.S.: By the way, you can mix Ciaplis with alcohol without any harm!

RE: NDMP performance with a 960
by John Clear 27 Mar '04

27 Mar '04

Many small files isn't too much of a problem on fulls, but is painful for incrementals. I have a 650GB qtree with 10 million files. The full takes about 16hrs, and the incremental takes 3-4hrs, most of which is just figuring out which files to back up. On both full and incrementals, no data is written to tape for the first 2+hrs. This isn't as big a deal on fulls (~40GB/hr average), but makes incrementals take much longer then similar sized volumes with fewer files. Once either the full or incremental starts moving data, the speed is similar to any other data. John
