RE: Netapp trunking - no performance gain

Sorry no experience with this switch... > The odd thing is that when I setup two gigabit lines trunked together >from the netapp to the switch I saw no improvement in thoughtput >compared to a single gigabit line. Again, not familiar with this particular switch...however, I have setup an enviornment similar to what you described and did see performance increase instantly. Extreme Summit 200-48 with a FAS250. I created a single vif interface out of the 2 gige interfaces on the FAS250 and enabled sharing on the switch ports that they plug into. I then took two 10/100 cards on a server and bound them togther and enabled sharing on the ports for the switch too. I went from pushing about 10MB/sec from the server to 20MB/sec. As this is well below the theoretical maximum for two gige ports trunked together, 250MB/sec (125MB/sec each), the problem is that pushing so little data makes it hard to see how effectively the gige trunk works. So, to answer your original question, yes I have done it; but utilizing 10/100 cards doesn't do justice when testing performance on a gige device.

RE: reuse old NetApp shelf

Why do 'some' people that reply to these emails not read them first?? Tim, if you bothered to read my origignal emails you would see that it is you that is ignorant by replying in that fashion. If you can't be more helpful why not refrain from answering? I maybe inexerienced as far as reusing NetApp FC disks in this fashion, but as per my previous emails you would have seen that I know enough with out the 100's of people telling me that they need to be low level formatted - see 1 st and subsequent emails. That's not the problem I've got that done but I can not format them ala Windows 512 sectors. See previous comments about diskpart & gdisk32, etc. As for the response sugesting using a different shelf, well that wouldn't be reusing the DS14 would it? It's something I may have to do, but before doing so I thought I'd ask to see if anyone could suggest a way of 'reusing' the DS14 shelves. Now, your point about disk manufactures utilities to format the disks is a bit more along the right lines, at least it addresses the question. The details about the mylex is helpful, I'll check that out.

This is a copper card with two HSSDC connectors so depending on which style LRC's you have, you may need to do some optical to copper conversion. Now the LRC and the disk firmware were designed for NetApp, so you would still be better off with generic disk firmware and a shelf designed to be Windows compatible. Better yet, just put these DS14's back on a filer and run FCP.

Netapp trunking - no performance gain
by Chris Moll 25 Mar '05

25 Mar '05

Has anyone gotten any performance gains from network interface trunking with a netapp? So far I haven't.... my suspicion is that I don't have the switch setup right. ----- More details: I'm trying to setup trunking on a netapp connected to a Cisco 3550 gigabit switch (OS vers.12 on the switch). The odd thing is that when I setup two gigabit lines trunked together from the netapp to the switch I saw no improvement in thoughtput compared to a single gigabit line. As a test I set up four 100Mbit interfaces trunked together from the netapp to the switch. Again, I see the same throughput as with a single 100Mbit interface alone - there was no gain in throughput from adding three more interfaces. (Measured by connecting a Sun to the switch with a gigabit interface). The trunking worked even before I set anything on the switch. The only thing I knew to do on the switch was put the interfaces in a channel group: switch> interface range GigabitEthernet1/0/17 - 18 switch> channel-group 1 mode on switch> end ...but still no change in throughput (this worked with sun trunking, and there I did see a gain in throughput). netapp> vif create multi romvif0 -b rr e4a e4b e4c e4d netstat and vif status both show roughly equal numbers of packets on all four interfaces; all four are definitely being used. -Chris Moll Lawrence Berkeley National Laboratory
