How would you respond to this
by Barry Lustig 24 Apr '01

24 Apr '01

This is an excerpt of an email that was sent to the management of a company that I'm working with. 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.

RE: Vif and Cluster setup questions

I'll try ifconfiging the vif without 100tx-fd and see what happens tonight. I've been up all night working on W2K issues so I'll try it tonight. I also have a bunch of quad cards from our pix firewalls, I want to try out. art -----Original Message----- From: FPS France [mailto:fpsfrance@fps.fr] Sent: Tuesday, April 24, 2001 12:37 AM To: Art Hebert Cc: toasters(a)mathworks.com Subject: Re: Vif and Cluster setup questions Bypass the e0 device : well done ! This device seems to be... proprietary in a way. About your 100Mb/s limitation, do you limit the rate in ifconfig ? like : > ifconfig vif01 `hostname`-e6 mediatype 100tx-fd partner vif01 may be you could try : > ifconfig vif01 `hostname`-e6 partner vif01 As Sam said, there should be no problem to use the same name.

RE: Redundant FCALs with ONTAP 6.1
by Traitel, Eyal 24 Apr '01

24 Apr '01

Chris, If I'm not incorrect, the redundant FCAL loop is not used for data transfer unless there is a problem with first loop. In this regard, even if 2nd FCAL card is not in an ideal slot, it would not matter that much. Nevertheless, it is better to avoid it altogether if possible...

But presuambly not now that Sam Rafter set us straight on the subject in his toasters posting of 12 Jan 2001... or could the scenario of burt 19290 ever apply in the context of "redundant FCALs"?

filer-mrtg on Solaris (Intel)
by Malek Hamdan 24 Apr '01

24 Apr '01

Hi all, Has anyone been successful in getting filer-mrtg working on Solaris (x86) ?? The rateup binary is for Sparc Solaris and using the latest rateup binary (mrtg 2.9.12) does not seem to work. I keep getting this error: PROBLEM: rateup died from Signal 8 with Exit Value 0 when doing router 'filer1.net.snmp' If this happens all the time, you should probably investigate the cause. :-) Does anyone know what I might be doing wrong?? Kind Regards, MH

logging snapshot events
by Todd C. Merrill 24 Apr '01

24 Apr '01

Is there a way to log snapshot events? I.e.: Sun Apr 22 02:29:13 EDT [consumer]: Disk scrubbing finished... Sun Apr 22 08:30:46 EDT [snapevent]: Snapshot test created on vol vol0 by user luser from machinename Sun Apr 22 08:31:46 EDT [snapevent]: Snapshot test renamed to test2 on vol vol0 by user luser from machinename Sun Apr 22 08:32:46 EDT [snapevent]: Snapshot test2 deleted on vol vol0 by user luser from machinename Sun Apr 22 08:33:46 EDT [snapevent]: Snapshot test3 created on vol vol0 by user luser from console [...] Mon Apr 23 00:00:02 EDT [snapevent]: Snapshot nightly.0 rolled on vol vol0 by user root from scheduler [...] Etc? Sometimes, as today, I find snapshots that should be there aren't, and it takes a while to find out how they disappeared. Sometimes, I never do find out how they gave up their mortal bits. Until next time... The Mathworks, Inc. 508-647-7000 x7792 3 Apple Hill Drive, Natick, MA 01760-2098 508-647-7001 FAX tmerrill(a)mathworks.com http://www.mathworks.com ---

RE: Vif and Cluster setup questions
by Art Hebert 24 Apr '01

Status so far. I decided to bypass the E0 network port and put another nic out of a pc I had in slot 5. I then tested in single mode and multi mode and everything worked great. I'll try out cluster failover tommorrow. Since I have each nic going to a different network card on my cisco 6509, I decided to hit the netapp from machines on each of the network cards on the cisco and instantly saw traffic on both interfaces. It only maxed at a 100mb thoughput and was distributed between the interfaces on the Netapp. I was hoping to be able to get double the performance. Is this a limitation of the bus or the virtual Interface? thanks art -----Original Message----- From: FPS France [mailto:fpsfrance@fps.fr] Sent: Monday, April 23, 2001 3:51 AM To: Art Hebert; Sam Cramer Cc: toasters(a)mathworks.com Subject: Re: Vif and Cluster setup questions Hi, I think what Sam Cramer said about switch might be considered : > A multi-mode vif will, when attached to a switch or set of interfaces on > another host capable of trunking, balance network load across its > constituent links. Most switches distribute the load across the links by > hashing an incoming packet's source and destination address. Thus, if > incoming packets share the same source and destination address, they will > flow over the same link. This may be what is biting you here. Try to get an expert from the Cisco support to help you in knowing how to configure your Cisco 6509 switch, and the way you could make some tries to see if it works. Also , I wonder if you do not bad in using identical names for your devices (vif01 in both Filer). Also (again), try to use ifconfig only to set up the IP adress. Instead of : > ifconfig e6 mediatype 100tx-fd > ifconfig e0 mediatype 100tx-fd > vif create multi vif01 e6 e0 > ifconfig vif01 `hostname`-e6 mediatype 100tx-fd partner vif01 you could try : > ifconfig e6 mediatype 100tx-fd > ifconfig e0 mediatype 100tx-fd > vif create multi vif01 e6 e0 > ifconfig vif01 `hostname`-e6 partner vif02 At the end (not also), I noted in you sysconfig -v output that one of two interface was down. So to be sure you right use single or multi here is : - failover purpose : ifconfig e1... ifconfig e2... vif create single vifa e1 e2 vif favor e1 ifconfig vifa... - loadbalancing purpose : ifconfig e1... ifconfig e2... vif create multi vifa e1 e2 # no favor expected ifconfig vifa... Thank you to let us know how it works.
