ndmpcopy error message
by Manny Kaiser 05 Nov '00

05 Nov '00

I get the following error message when trying to use the ndmpcopy command (latest version 1.2) on a F840 running 5.3.6H1R2. The command and error messages are: ndmpcopy netmmc:/vol/vol1/projects/nguc netmmc:/vol/vol2/nguc Password: Connecting to netmmc. Connecting to netmmc. init: error sending NDMP_MOVER_LISTEN message: Error: Connection has not been authorized On the Netapp console I get: Nov 05 06:27:21 [ndmpd:33]: Top level IOException Nov 05 06:27:21 [ndmpd:34]: Top level IOException Nov 05 06:27:21 [ndmpd:33]: IO exception: Socket closed. Nov 05 06:27:21 [ndmpd:34]: IO exception: Socket closed. Any ideas?

Is news so important to you that you would put it on a filer? That's one thing I stick to JBOD... price out two terabytes of usable storage on 50GB or 72GB drives in decent enclosures over U2SCSI or FibreChannel, and compare it to an F760 with the same amount of space. If you're concerned with performance of millions of small files, switch to a different storage model... it will almost certainly be cheaper than a big Netapp. -- Or switch to a more efficient method of running news (IE: Highwind).

For both performance and supportability reasons, it is extremely inadvisable to put Exchange mailboxes/private stores/public stores on anything other than a filesystem which is directly-connected to the NT server in question. People do all sorts of odd things with NetApps just because they can - and don't get me wrong, I love my F740 - but this is just plain crazy. For your own peace of mind, don't do it. ----------------------------------------------------------- Roland Dobbins <rdobbins(a)netmore.net> // 818.535.5024 voice -----Original Message----- From: Jamie Carr [mailto:jcarr@caseshare.com] Sent: Friday, November 03, 2000 3:22 PM To: toasters(a)mathworks.com Subject: Exchange 2k We are in process of deploying Exchange 2k to our clients, but no one has been able to answer the question of weather or not we could store Exchange 2k mailboxes on our toaster (NetApp 720) and be Microsoft compliant.

:As far as using it for Exchange, *I* would, but that's me. :Generally, Microsoft and NFS don't mix well, even though :they give lots of lip service to it. Martin, To my knowledge MS and NFS don't mix well... but have you heard that NetApp Filers have been directly supporting SMB (or CIFS) protocol for years now. You don't have to use NFS to put Exchange or any other data on the filer. We use CIFS, which Microsoft also uses for NT networking. So you use the clients software and protocols native to Windows Platform machines. You simply license CIFS, add the filer to an NT4 or Windows 2000 domain (or run the filer in 'workgroup mode') and your clients see the filer 'just like' an NT4 member server. ... ... but that is the subject of another thread that I really don't want to start right now *grin* Its the weekend after all!

Actually people are successfully running MS Exchange 5.5 on filers right now. No, Microsoft does not officially support Exchange on NAS (though Microsoft DOES support SQL 7 on Filers). So we have worked out additional agreements with IBM to support Exchange issues when the databases are on the filer. Some IT groups are not allowed, by company policy, to do anything that is not officially supported by their vendors. For those it is too bad. Others get the benefits of the filer and SnapManager for Exchange. Of course the decision is yours - or your CIO's, managers, etc. Check out the following white papers, see what you think. If you have any questions please feel free to ask... Microsoft Exchange and NetApp Filers : An Overview http://www.netapp.com/tech_library/3067.html Technical Installation and Integration Supplement http://www.netapp.com/tech_library/3054.html Recommendations for Deployment http://www.netapp.com/tech_library/3074.html These Press Releases are also relevant : NetApp Unveils First Online Backup and Rapid Data Recovery Solution for MS Exchange http://www.netapp.com/news/press/news_rel_20000207.html NetApp Taps IBM for Microsoft Exchange Support Services http://www.netapp.com/news/press/news_rel_20000207a.html As far as Exchange 2000 on the filer, so far as I know, MS does not support that either. I know of one customer that was setting it up on the filer . He didn't call back with any problems so chances are its running smoothly. (I do tech support so I only hear from customers that have questions *grin*) On a side note, the customers I talk to that have contacted Microsoft about Exchange issues with their databases on the filer have not been 'hung up on' so to speak. BTW. If you want to talk to an Exchange Admin who LOVES Exchange on the filer let me know privately. I will not post his name or number here, but he is usually willing to talk to people about it.

In search of the ideal hardware config...
by Alf Mikula 03 Nov '00

I'm looking for performance tuning tips for NetApps. We're looking to upgrade from F760's with 9GB 7200rpm drives to F840's with either 18GB or 36GB drives. Due to the performance characterics of the system, more storage is not always better, but if I can work out a reduction in the number of spindles required to serve the same data, we'll save space and power in the datacenter. Degraded mode performance is also critical: we need to be able to reconstruct a failed disk in a reasonable amount of time, with minimal performance impact. My thinking is that performance and space requirements drive raid group size up, and degraded mode performance requirements drive raid group size down. I'm looking to find the balance. The relevant bottlenecks are: 1) CPU 2) Bus bandwidth to disk 3) Individual disk ops/sec bandwidth The questions I need to answer are: 1) How much CPU is required to do a particular number of ops/second? 2) How much data can I cram through the buses to the disk? 3) How many spindles do I need? 4) What should my raid size be? 5) How much of a performance hit will I take in degraded mode? Has anyone out there made an effort to solve the problem on this level? I'm working on answering 3) 4) and 5) above, and assume that I can derive results from benchmarks and specs to answer 1) and 2). To answer the spindle question, I need to know how many sequential block reads/sec, random block reads/sec, and sequential block writes/sec I can do with each disk. Any pointers you have would be helpful. Thanks, -Alf -- --------------------------------| It's Your Internet! Alf Mikula |-------------------------------------- Earthlink, Inc. |

Anyone trying out 5.3.7 yet?
by Chris Thompson 01 Nov '00

01 Nov '00

DOT 5.3.7 came out as Early Access at now.netapp.com last week (although there hasn't been a Field Alert about it). There are a lot of bug fixes, not much new feature. My impression is that it's an attempt to produce a stable final, or near-final, 5.x release. It's got the rsh-clobbered- -by-telnet.hosts bug (25783) fixed, for example. I am inclined to upgrade to it (we're on 5.3.6R2 at the moment) but, of course, I don't want to be the first to do so! :-) Has anyone else dipped their toes in the water yet?
