Spreading the network load will not reduce the cpu load. Given the output of sysstat in your mail, it probably won't help to add bandwidth, however, if you were to experience a different workload, more cached reads for example, you could easily exceed the capacity of a single 100Mb ethernet.

EtherChannel trunking
by Todd C. Merrill 09 Feb '99

09 Feb '99

Greetings. Has anyone configured a quad 100 ethernet card with EtherChannel trunking? I searched the archives for this lists and didn't find any subject heading with "EtherChannel" or "trunk." My proposed plan is (I hope it is this simple): o create a virtual interface with `vif create` o replace the ifconfig line in the rc file: ifconfig e0 mediatype 100tx-fd `hostname`-e0 with ifconfig vif1 mediatype ??? `hostname`-vif0 o reboot the filer There is probably a more elegant way to do this live and online, by downing e0 and then upping vif0, but I'll be doing this off hours anyway, so a reboot is not a problem. I've got a brand new F740 running ONTAP 5.2.1, and I'm new to NetApp filers, so please be gentle with a newbie to this technology. What a nice machine, though. Had it running at: CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 91% 1785 876 0 9346 1783 787 9056 0 0 8 91% 1858 722 0 9796 1100 182 10326 0 0 7 87% 2147 562 0 8924 1369 209 9138 0 0 8 83% 2007 934 0 7491 1330 147 8642 0 0 8 85% 2051 990 0 7703 1596 592 7265 0 0 8 for a while today; at this level, our previous file server (not a NetApp) would have long since fell over and died. If I've already nearly got it pegged in this peak operation (sustained is about 30-50%...so far), and the theoretical limit of the 100 Mb/s fd link is ~12,200 kB/s in and out, do I really need this quad 100 card? Will spreading the network load reduce the CPU load? Until next time... Todd C.

RE: NetApp CPU upgrade
by Benn, Paul 08 Feb '99

08 Feb '99

I can't vouch for whether or not a Filer's CPU can be upgraded but I can point something else out.... A 90MHz Pentium has an internal clock speed of 60MHz and a multiplier of 1.5 (60x1.5=90). On motherboards that allow configuration changes there are usually (at least) two jumpers, one for clock speed and another for the multiplier. A Pentium 133 has an internal speed of 66 and a multiplier of 2 (66x2=132 or 133). So, as you can see, a simple chip swap won't work (actually, it might work but without proper mother board support you'd still have a Pentium 90).

RE: Gigabit Ethernet Card
by Naden, Barbara 06 Feb '99

The 1000-fx designation on the filer is just a string and has no effect on the encoding on the wire. Unfortunately, it is also wrong. It should read 1000-sx. You should have no problems connecting to your switch.

RE: NetApp CPU upgrade
by Bulfer, David 05 Feb '99

The F230's performance is not limited by CPU clock rate. It is limited by the performance of the host bridge (a.k.a. north bridge). The host bridge defines memory bandwidth and PCI bandwidth. Overclocking the F230 won't solve a heavily loaded filer.

I had a lot of fun setting it up. :) And actually, I didn't even do the method without the port number, although I always wanted to go back and change that once I figured out how to do it on the Portmaster. That being said, if you don't like Livingston, er, Lucent, you can probably get Xylogics, er, Bay Networks, to work just as well. And as a former Purdue student, I have nothing against conserver at all, but I've yet to see it in full implementation across an entire machine room to know if it's truly worth the effort or not.

FreeBSD3.0 compatible with Packet Engines Gigabit?

I have a customer who recently upgraded from FreeBSD2.8 to FreeBSD3.0 and they can't seem to get their PacketEngines gigabit card to work. The card worked flawlessly with FreeBSD2.8. Is there anyone out there running this type of configuration?

Re: watchdog resets
by Steven D'Aurora 05 Feb '99

05 Feb '99

We had similar problems on our F630s. Turns out this was due to the system backplane stack height. The backplane standoffs were about 3mm too short! Since we have always been running 5.x.x of some flavor I'm not sure if it's OS related or not. Check to see if the card edges are fully seated in the backplane. The watchdog resets were a problem only after I had reseated all cards and the system was up for a couple of days/weeks (it did vary that much). Flex in the chassis was enough to dislodge the environment card that has the stupid watchdog cable on it. One system was bad enough the CPU board had "intermittent" connection to the rest of the system. The frustrating part was that Adaptec was the only site in this area to have this problem :( And it took me about 5 weeks to find it wasn't bad hardware. I went to a local hardware store and picked up some washers to pick up the backplane. A real pain to install but fixed the problems. After NetApp had found out about this manufacturing problem, all our F630 chassis were replaced with newer rev units that fix the stack height. Good luck! ____________________________________________________ Steve D'Aurora ESN - Engineering Systems and Network Administrator Adaptec Milpitas, CA, USA phone: 408 957 2351 fax: 408 957 4895 mailto: nevets(a)eng.adaptec.com ____________________________________________________ > Date: Fri, 05 Feb 1999 09:12:59 -0600 > From: John Tatar <tatar(a)dis.anl.gov> > X-Accept-Language: en > MIME-Version: 1.0 > To: toasters(a)mathworks.com > Subject: watchdog resets > Content-Transfer-Encoding: 7bit > > We have had a particularly annoying problem with our 540 filer over the > last several months.

watchdog resets

We have had a particularly annoying problem with our 540 filer over the last several months. We keep getting watchdog resets. As a matter of fact we just got another as I was composing this message. We get an average of one every other day. We have checked the cables, reseated cards, replaced cards, replaced the head. I am going to start replacing the power supplies on the shelves tonight. If that doesn't work, we'll replace the SCSI cables between the shelves and the head. This problem started after we upgraded the firmware and OS to 1.11a and 5.0.2R3 respectively.
