RE: Netcache rsh admin access
by Rousseau, Deborah 27 Apr '01

27 Apr '01

The hosts.equiv file is case sensitive to the case of the user name. should read: hostname username The hostname needs to be resolvable, so host file entry helps. The rsh command could be improved with the -l username perameter. rsh filername -l username command Try those.

RE: How would you respond to this
by Riley, Mike 27 Apr '01

27 Apr '01

Hopefully not adding too much fuel to the fire but we just went head-to-head with an IP4700 at a customer site with an F85. The customer ran their tests - we didn't furnish them with any - and the F85 out-performed the IP4700 on a consistent basis. We are asking the customer if we can publish their report. For the record, EMC does make sound products and has been a very successful company with great service. The key footnote, that I believe was mentioned somewhere in this mail chain, is EMC has ventured into a new market where the filesystem and OS "kernel" are integrally interwoven into the storage fabric. This is an entirely different paradigm for direct-attached vendors. Attaching disk to an NT or Unix platform and then expecting the filesystems that live in those operating systems to "do the right thing" is quite a different proposition when compared to NAS. To make a true NAS appliance, it's not as simple as stripping down an open-source OS and cobling it together with a re-cycled filesystem. True, everyone has to start somewhere - even Network Appliance had to start with publicly available device drivers, IP stacks, etc. - but to introduce a robust, functional feature set without compromising customer expectations on ease of use or performance requires knowledge and! vision based on experience. There is no better teacher than experience and Network Appliance has had 9 years to figure this stuff out and we're still working hard to improve, integrate new technology and even break new technological ground (e.g. DAFS). >From that standpoint, (and, yes, I have my NetApp hat firmly on now), claims from EMC that they can do everything NetApp can do (and the stuff that they can't do will ship in <fill in month here>), have to be taken with a huge block/pillar of salt, particularly if you have ever had the opportunity to compare the products side-by-side. Outside of the critical product differences today, the assumption moving forward is that somehow NetApp will stand still and that simply isn't the case; can't be the case. EMC is very new to this game, and as big as they are, if you look at most of their press releases they mention that they are trying to "catch Network Appliance" - their words, not ours. We believe, based on customer input such as yours, that we will continue to lead this market from both a technology and sales perspective. -----Original Message----- From: Network Appliance List [mailto:nalist@mail.bokf.com] Sent: Wednesday, April 25, 2001 5:43 AM To: 'toasters(a)mathworks.com' Cc: Howland , Jerry; Hammack, Tom Subject: FW: How would you respond to this Gawd. I always knew that EMC was lower than a snake's belly in a wagon wheel rut, but gee. I'd just educate the management types, addressing each point.

They had spec'ed F85's for a fairly low performance 10-20Mbits/sec. environment. The main requirement is reliability and ease of use. How does one respond to blatant misrepresentation of a competitors product? barry A few highlights of the comparison: - The F85 is a stripped down, single CPU, low end device with multiple points of failure and a very poor data protection. NetApps service is rated very low by industry experts and they offer next day shipment of parts that the user must install themselves. - The IP4700 is fully redundant, multi-CPU, mid-range device with no single point of failure and hardware based RAID 5 data protection. EMC's world class customer service center has ranked #1 for 6 consecutive years by Gartner Group. Standard 2 year warranty guarantees 4 hours ON SITE w/Parts service by EMC technicians. Plus, our 'call home' proactive maintenance system monitors trends within the system and reports them automatically to our customer service center. Often, EMC technicians will repair a system BEFORE the component actually fails. The 4700 will be configured with 8 drives usable, plus 1 drive for RAID 5 parity and 1 drive for hot swap redundancy. It is scalable all the way to 7000GB (7TB) vs. only 648GB for the F85. The 4700 as configured above is 8RU. In general, the F85 does not scale sufficiently for growth, has poor customer service behind it, has no redundancy, has multiple points of failure, and utilizes a sub-par RAID 0 data protection scheme.

File path error
by Maglinger, Paul 27 Apr '01

27 Apr '01

We have a NetApps 740 running 5.3.7R2. We run NT on our workstations. One of our people wrote a VB program that uses a filecopy command to take a file from an NT workstation and copy it multiple times, each copy with a different name, to a filer share. According to him, if he copies a series of files and the first file is greater than 10K, it will successfully copy the remaining files with no error. If the file is less than 10K, he gets a "file path error" copying the first file, but the file will have copied. The error causes his VB program to halt. Any thoughts out there?

I have added mixed sized disks into the same volume, but different raid groups using this method *many* times in the field - it works like a charm. You can bet my life on it too. :-) The parity disk functionality has been there for a long time. It worked that way when I put the just released 18 GB drives into a 9 GB drive system way back when......

I went to ask the lab manager if I could do some vol destroys on a few filers to get some mixed disk sizes. Our lab manager, Jeff Mohler, is a reformed PSE, and he'd done the very experiment I was about to conduct at customer sites, many times. Rest assured, you don't need to create a new volume. Look at your sysconfig -r output presently. Since everything's in one volume, the last raid group listed (raid group 1, if you have two raid groups like you say you do) is the raid group that's subject to change in size. This is controlled by the vol option raidsize. Set the raid size to whatever this raid group size is presently by 'vol options <volname> raidsize <n>'. Add your disks. If the number of disks you are adding is greater than <n>, add some number of 36G drives less than n, and change the vol option to the number of 36G disks you intend to add. I had fears that the raid group size would be stored in the raid group by some pernicious machinations, but Jeff assuaged any such trepidations. I'll bet Jeff's life on it. If you have one 18G spare, and one 36G spare, ONTAP now has the smarts to pick the right sized spare. If you are using mixed raid group sizes, I recommend you run ONTAP 6.x to take advantage of the spacemap, and avoid some unpleasant endgame scenarios if you do manage to fill up your disks. -- Sam Rafter Escalations Jerk Network Appliance rafter(a)netapp.com Sam Rafter wrote: > > This used to be the case.

RE: "Case survey" stuff from NetApp
by Sullivan, Justin 26 Apr '01

26 Apr '01

After Mr. Thompson's excellent suggestion of yesterday, we are already working on integrating the customer surveys with the case information on our NOW site. For example.. You receive a message about a survey, click on the link, login to NOW, and the case information is there and a place where you can fill out the survey with your comments. Customer feedback is EXTREMELY important to us. I really can't stress how vital it really is. You should *NEVER* get "okay" support from Network Appliance.. It should always be AT LEAST "good". Regrettably, if you only get "okay" support, we have no way of knowing if you don't fill out the survey. :) But it is our mission to "Simplify the Customer Experience," and this is an excellent point. Click.. Fill out survey.. Click.. <makes sense to me..> - Justin -----Original Message----- From: Stuart Lefort [mailto:slefort@broadcom.com] Sent: Thursday, April 26, 2001 11:46 AM To: 'Mohler, Jeff'; 'Sullivan, Justin'; 'Chris Thompson'; toasters(a)mathworks.com Subject: RE: "Case survey" stuff from NetApp Not true Jeff. I discard the surveys - always. Reason. Insufficient information to describe what this case is about. I would prefer the email had a link I could click on that would take me back to the case so I could be recall the case - then allow a rating right then and there. Alternatively, the email could have MORE case information in it - and I would reply to that. But I won't reply to something where I no longer recall the facts. ...Stu -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Mohler, Jeff Sent: Wednesday, April 25, 2001 3:44 PM To: Sullivan, Justin; 'Chris Thompson'; toasters(a)mathworks.com Subject: RE: "Case survey" stuff from NetApp I would think that it would take more of my time, to load up the WWW browser to work it there, than to insert five numbers between the ()'s. -----Original Message----- From: Sullivan, Justin [mailto:Justin.Sullivan@netapp.com] Sent: Wednesday, April 25, 2001 1:22 PM To: 'Chris Thompson'; toasters(a)mathworks.com Subject: RE: "Case survey" stuff from NetApp Capital idea.. We would certainly like to have more surveys returned - we should like to see EVERY survey returned. You have an excellent point - why not have a web-based survey form? Easy, friendly, quick.. Back in the days when I was a NetApp customer, I admit, I threw them away too - too much trouble to fill out the e-mail form; who has that kind of time anymore? I have passed your idea along to the folks in Customer Satisfaction who can make this happen.

I admit I throw them in the e-wastebin. It seems to me that providing only a method of returning these (probably only marginally meaningful) answers by e-mail is absolutely pessimal. If they really want to increase the response rate, surely NetApp should provide a method using forms at now.netapp.com? My vague recollection is that at one time a WWW-browser-based method was offered, but this doesn't seem to be the case now.
