Re: load tracking

If so, I'd like to hear > about your experiences. We use mrtg to plot things like nfsops/sec, network i/o, disk space status, etc. All these data are collected using snmp, qhich is what mrtg usually does, anyway. This gives us, without too much hassle, a graph of tha last 24 hrs, last week, month and year - these graphs can be very useful to track down various problems (and to monitor available diskspace). Mrtg is free software, i can't remember off the top of my head where to find it, but it should be quite easy to find. If there's any interest I'm sure I can dig up some example configs from our setup. -- ---Ketil Kirkerud Elgethun, SOL System

Filer and IIS
by Jimy Liu 20 Apr '98

20 Apr '98

Hi sirs: I have one filer share directory to one NT server.(NT mount filer's /home/www as its f:\ directory) And I set up Internet Information Server(IIS) Web's root directory as f:\ . Then I use brower to open NT's web page from IIS. The browser show "Can not find the object". And in IIS web directory setting shows "this directory access denied. But I can using brower to open file in f: directory . Why can not access through IIS ? There is must something wrong on filer or IIS . Jimy

I know in a previous version, we ran into a problem where the CPU pegged high when scanning a deep directory tree, hundreds or thousands of entries deep, that someone had created. I believe this impact was alleviated in later releases but I can't be certain of that having not tried it myself. So, unless your filer is just heavily loaded and/or short of memory when doing your backup, I'd suspect something like a deeply nested directory tree. Perhaps you can locate it an remove it. Then again, it could be something entirely different. :/ Bruce

It is not unusual for Microsoft to violate their own spec. I don't know specifically what is wrong in IIS, but probably the filer is advertising something perfectly reasonable (that win95 doesn't), but IIS isn't handling it correctly. If Microsoft says this is a problem with IIS, then I see no reason to doubt them. (Yes, they may initially accuse Netapp, but the impression I am getting is that they aren't doing so now.) >About two month ago, my customer ran Notes server on NT using NetApp >filer => Notes boot Fail . >If she ran Notes server on this NT using another NT's disk as network >drive => Notes boot Success. Again why filer can't ? >(ps: I hope to resolv IIS with filer first ) I know these sorts of things happened in earlier versions of the filer CIFS software. Whether or not it happens now is hard to say. I would upgrade your filer software, try it, and if it still doesn't work, contact Netapp so they can open a bug on it. Bruce

Silly Microsoft. :( I dunno... seems like Microsoft "won" to me, since you didn't abandon IIS. Instead you were coerced into a more expensive and more NT-centric solution. (Before someone questions whether or not such a solution is really more expensive, please don't... I don't want this to turn into some flamewar about Microsoft and/or NT.) Bruce

The small amount of failures that NetApp finds >could be attributed to manufacturing defects and delivery problems. I basically agree (I'm not sure if I'd draw the line at 1 in 200), but I would point out that if they can be attributed to manufacturing defects, then you are just as likely to get such a defect direct from the supplier. So again, going through a supplier like Samsung isn't going to be more reliable, although how much less reliable (i.e. 0.5%) may be negligible for your particular environment. It would, however, somewhat dispel the notion that the filers push the edge of the components. Bruce

Re: Data ONTAP 5.0 memory requirements

Thats not dropping to me. We just paid NetApp $4000 to up the NVRAM on our F330 from 2MB to 8MB. That's over $650 for each 1MB SIMM! When I asked our Sales Rep about the cost, I was quoted the "We do in house testing" line. Anyway, two of the SIMMs we were sent were bad... Very disappointing. I think it'd work out best for everyone if they just published a list of "approved" vendors for memory and disk. The customers would get a better price, and NetApp would look alot nicer. jason >--- On Thu, 26 Mar 1998 17:30:52 +1100 Mike Bosch <mbosch(a)netapp.com> >wrote: > >>Marc, >> >>As I recall, Cisco was requiring 64MB and recommending 128MB on most ISP >>7500s over a year ago.

I'm afraid you're the one who misunderstood; within the context of the discussion, we were distinguishing between the original vendor of the component and getting it straight from Netapp itself. Thus, when I say third-party components are less reliable, I mean "If you get Samsung DRAM from Samsung, it's going to be less reliable than if you get Samsung DRAM from Netapp" in this context. You suggested another vendor was required; perhaps you didn't think I meant Samsung in the first place. But that's what I asked... what vendor do you think is more reliable, or at least the same reliability, getting it direct than from Netapp? In other words, are you saying the Samsung memory you get direct from Samsung is more reliable than the Samsung DRAM you get from Netapp? As has been pointed out before, Netapp tests DRAM they get from Samsung before it goes out the door, and does find failures, so I can't see how Samsung direct could be any MORE reliable, unless Netapp somehow damages the DRAM in assembly or shipment.
