I see your point about NFS ops. I would guess then that if this customer was seeing a high percentage usage of the cpu then that would be the indicator that the box was overloaded. And that's not something one can easily extrapolate from the cpu performance of Suns or any other boxes. Estimating the size of filer needed doesn't seem very straightforward then, except by disk sizes. Dave

Ladies & gentlemen, We use FAServers at our department since Feb. 1994. Since then we have had five units from model 450, F330 to F540. At one point or other our NFS clients were HP, Digital, IBM/RS6000, SGI, Convex, Apollo and even MAC (via Xinet software). Packages range from Cadence to Framemaker to other semiconductor manufacturing related simulators. We have documented uptime of over 99.7%, which includes scheduled downtime. Its truly a lights out operation. Needless to say I am a big fan of the product, to date. Yet, when a sisterly department was looking into NFS fileservers, FAServer was brushed off their short list, which included only SUN and Auspex. Even after two hours of discussion with one of the key IS member I still was in the dark on why FAServer was not even in the running. >From what little I could gather, the only sour note on FAServer was "Network Appliance lack of industry standards"; whatever that means. My guess is that the other prominent players were pointing to the fact that FAServer file system is not "BSD or System5", their OS is not "UNIX" and so on and so forth. When I look at NetApp's brochure, there is no reference to any "standards" or their membership/affiliation to any of the scores of industry consortiums. I tried my best to get something in writing from NetApp stating their commitment on standards. Folks, I know this is absurd. But I had to do it. Anyway, NetApp conveniently ignored my request. So this is you mission, if you chose so... Please let me know if the alleged "lack of industry standards" effected your operations? If it's not against your company policy, it may help, in future, to know (a) what type of industry is this FAServer used? (b) how many FAServer and approximate total disk space? (c) which part of the world are this installed? (d) how important is standards based tools to your company and why you picked FAServer when they seems to be build on proprietary environment? (e) what is your performance and uptime experience with FAServers? (f) how critical is FAServer's uptime for your company/department's operation? (g) installed since when? (h) any experience you can share between FAServer and Auspex/SUN file servers? Thanking you all in anticipation. Philip Thomas Motorola - ACT, M/S M350 2200 W.

NetApp v Suns
by Dave Heiland 17 Jun '97

17 Jun '97

We're evaluating an F540 and I'm wondering how many of you compared them against the Suns. Specifically we currently run 2 Ultra 170's plus arrays which both see about 1200-1400 nfs ops/sec average with frequent peaks of 2000 on one. The one box holds common areas, the other builds. I'm considering upgrading these to 2 Ultra 2's with dual 300Mhz chips (for performance and arrays), or one F630 (200GB). >From what I can see of the LADDIS numbers, the NetApps respond faster than the Ultra 2 range and its not until you get to the Ultra 3000 that the response times are comparable, even though the Ultra 2's would sustain higher nfs ops. Is this something people have seen in practice? I'm initially considering one F630 for price reasons and since the one box sees higher nfs/ops but the other box is the one needing the extra storage. The 'limit' of 4500 nfs/ops on the F630 concerns me in that combining the current nfs ops can easily put use near the upper limit of the box. What I don't have a feel for is how many nfs ops the current workload would actually put on a filer. If it responds faster to clients, then I'd actually expect the nfs ops to be even higher, putting me even nearer the limit or above it (although I know its not limited to 4500 nfs/ops, I assume its response would drop significantly). Have people found this to be the case? Two F540's are a possibility, but we seem to be approaching their upper limit and if we go over there isn't room for expandability, whereas we could (eventually) add a second 630 and split the serving again if we choose to go this route. What kind of loading are people seeing on their netapps, e.g. 500nfs ops, 2000 nfs ops, any over the limit of the F540? Dave -- dheiland(a)lucent.com

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

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. While the list of alternative peripheral components may not very extensive, we're doing our very best to give you that option should you desire to pursue that path. | 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).

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.

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"
