Exchange 2k
by Jamie Carr 04 Nov '00

04 Nov '00

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. We are currently using our toaster to store general data i.e. pdf's doc's etc. I am sure that the toaster will be able to store the data, but the question is restoring data in the event of deleted mail boxes etc. Microsoft has not said anything about this type configuration on a Exchange 2k box. I know lots of people who are using their toasters to store Exchange 5.5 mail boxes but none using 2k as of yet. Has anyone tried this and what success/failure has any one encountered. I would like this work on the NetApp and not have to deploy and develop another storage solution, because in my mind there is nothing else out there that can beat a NetApp in availability and durability. Thanks, Jamie Carr

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?

syslog appliance avail ??
by Colin Johnston 27 Oct '00

27 Oct '00

Hi, please ignore my email if you think not relevent to the toasters or cache email lists Does anyone know of a 'syslog' applicance box that has a nice management interface to system, has a nice archival system for old logs and can cope with large amounts of file store for old logs. I am well aware this can be done with unix boxs etc and raid arrays but it seems since syslog is a single function the applicance route map maybe the bext method of progression. a newreader functionality to read the syslog store would be useful as well. storage of cache logs via ftp would be useful as well. storage of archival system email would also be useful. I am happy to beta test any such appliance and give feedback to the supplier. Colin Johnston SAEU PSINET UK

mount: RPC: Authentication error; why = Client credential too wea k
by Rainchik, Aleksandr (MED, Non GE) 27 Oct '00

27 Oct '00

Hello, From what I've found, NetApp filer will refuse mount requests if the source port of that request is less than 1024, or "unprivileged". The problem we have right now is accessing NetApp trough the firewall. So we have a couple of NetApps and Sun servers that are behind port-mapping firewall. I can mount everything from Sun, but when we are trying to mount something from netapp, I get this error message on a client client% mount netapp1:/some_dir mount: RPC: Authentication error; why = Client credential too weak With tcpdump I see how mount requests from client (client.678 -> netap1.sunrpc)are being translated on firewall: firewall1.61128 -> netap1.sunrpc My question is, if there is a way to put netapp in a less secure mode, to allow mount requests from unprivileged ports? Thank you

mrtg

Hi, I downloaded the filer mrtg and have been able to get it running on my 840. What I have discovered is that the disk usage is not showing. Anyone have any pointers what the problem might be? Thanks

RE: mrtg

The "transparent" option was added in MRTG 2.7.1 (according to the CHANGES file in the latest version of MRTG). The version of MRTG included in the NOW download package (which combines MRTG with some Filer-specific configuration things) is older than that, so that explains why it doesn't recognize "transparent". Regarding the disk usage problem, I just tried the NOW version of MRTG with the latest version of ONTAP, and didn't see any problem with the disk usage. Please send me additional details on your setup (exact version of ONTAP, any customizations you've made to the MRTG package), and I'll look into it further. ...Tim Thompson...Network Appliance, Inc... -----Original Message----- From: Manny Kaiser [mailto:mkaiser@mmcnet.com] Sent: Thursday, October 26, 2000 6:27 AM To: Mike Knell Cc: toasters(a)mathworks.com Subject: Re: mrtg I get an error message when I add "tranparent" to the options line Mike Knell wrote: > > I downloaded the filer mrtg and have been able to get it running on my > > 840. > > What I have discovered is that the disk usage is not showing. > > I seem to remember having to do a bit of fiddling with the mrtg stuff > to get it working properly.
