If NetApp claims to support SMTP, it would be nice if you could fix the bug where SMTP commands from a NetApp box are only terminated with LF, not CRLF as RFC 821 explicitly specifies. (I reported this on 12 March this year, and later heard that it was acknowledged as a bug, bug #4268.) Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

NetApp publishes the "Product Configuration Guide" during every new product rollout that contains a section on supported 3rd-party peripherals. The only condition here is that we don't provide service or warrant those components that originate from outside of NetApp. Please contact your account manager for the latest version. A revised version is in the works and is expected to be made available within two weeks. An advantage of being an appliance company is that we use whatever processor technology that's best suited to serve the particular market segment. A disadvantage of having an agnostic view towards processor technology is that it does introduce more permutation/combination of peripheral technologies (for example, different memory types for Intel vs. Alpha) for testing and qualification efforts. I believe NetApp would have served our customers better if we put our focus in maintaining innovation in software, and innovate hardware for best reliability and performance.

Apologies if this is off the charter -- let me know (gently, please!) and I'll desist -- but I'm evaluating dedicated NFS servers and have narrowed things down to Network Appliance (F220, qty 2) versus Falcon Systems (FastfilePro 7000, qty 1). I must admit that I'm leaning toward the 7000 due to its superior expandability and greater administrative flexibility (multiple filesystems and RAID sets, ability to run old drives via JBOD on the SCSI port). Also, the 7000 tests about even with the F540 in various magazine reviews, and NetApp's own LADDIS testing shows the F220 to be only half as fast as the F540 (is this true in the real world?). On the other hand, NetApp tells me that the highly random nature of my traffic -- typical ISP work including email, USENET news, and webservers -- should point me toward multiple servers to maximize main memory cache hits. They say that the main memory cache on the 7000 will become worthless as I expand storage and that performance will drop off. I don't have a good feel for the importance of main memory cache here -- the 7000 uses hardware RAID controllers with onboard cache, so it seems like it would be less important to the Falcon product than it is to the NetApp line. But I must admit that NetApp's larger installed base -- 1000's versus 100's of systems -- makes it a safer choice on the surface.

Let me know via personal or newsgroup email if you are getting the performance you expect from the F220 and F330. What type of network are you on (10, 100, ATM, FDDI, etc)? ---} In enteract.private.lists.toasters, David Drum <david(a)more.net> wrote: ---} ---} > Brian Tao penned: ---} > ---} > > Just checking to see if anyone else is alive here... ;-) ---} > > ObInventory: got an F220, getting two F210's and an F230. :) ---} > ---} > Hi Brian, ---} > ---} > My F330 was delivered yesterday, and set up today (thanks Jeff West!). ---} ---} Me too. :)

Third-party components for F210 and F230
by Brian Tao 13 Jun '97

13 Jun '97

Does someone have a Netapp-approved list of components that can be used with the F210 and F230 filers without voiding service and support warranties? I bought a minimally configured F220 a few months ago, and populated with third-party RAM from Kingston, Seagate Barracuda 4.3GB narrow SCSI drives, and DEC StorageWorks canisters. The total cost came out to 30% less than an identical system put together by Netapp. The new filers use fast/wide drives (I heard that Fujitsu drives are now on the approved list) and a different canister (metal instead of plastic, for one thing). Does anyone have vendor and part numbers for those components? Much as I love Netapp, I still find the pricing a wee bit steep. ;-) -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

We currently run with NFS v2/UDP on our NetApp. The change from v3 to v2 resulted in a noticeable decrease in expiry time for us. The disadvantage of NFS v2 is that you won't be able to get number of inodes (files) via NFS. I like the suggestion from Guy Harris to deal with this: Use two mount points for the NetApp file system - one NFSv2 for the main News spool, and one NFSv3 to be able to check inodes, selected by suitable mount options on client.

mixing 4Gb and 9Gb discs
by Tom Yates 05 Jun '97

05 Jun '97

here's the situation. i have an F330, currently with 20 4Gb discs in three shelves. it is not performance-bound, it's capacity-bound. i'd heard (from netapp) sometime back that, at some future date, mixed 4 and 9 arrays would be permitted, but that i couldn't remove existing 4s, and that 9s would require a dedicated shelf. therefore, i'd tried to keep my disc load on three shelves, and so far succeeded. if i understand correctly, whilst i will shortly be allowed to mix 4s and 9s, i won't be allowed to use a full set of 9s - in fact, i'll be limited to 21*4 + 3*9 for data, with one hot spare and one parity, leaving me two disc slots i can't use. is this in fact the case, and if so, would anyone care to try to explain why, *bearing in mind that this toaster is definitely not performance-limited*?

CIFS and HTTP performance
by Aamer Latif 22 May '97

22 May '97

I have a couple of questions regarding CIFS and HTTP performance on NAC filers. Appreciate any answers regarding these. In reviewing the CIFs performance white paper on the NAC website (http://www.netapp.com/technology/level3/3015.html), I'm unclear on what type of NetBench test is being run. Specifically, I'm not sure if the paper describes NetBench Disk Mix or Random Read/Write tests. I'd thought that the graphs pertained to the Disk Mix test but block size variation test (section 3.1 in above paper) made me think that perhaps Random Read/Write test was being described (Disk Mix does not allow the I/O block size to be varied? If the Read/Write test is being used, I would be very interested in knowing the file sizes that are being used in these tests. Second, I'm wondering if there is any info or experiences regarding how many http op/s can a Netapp Web filer support? Thanks! Aamer a.latif(a)ieee.org
