Steve, Depends on your app. Trunking just allows alternate paths for data: you're not going to be able to push 4 Gb/s over a single link on that bond. Rather, if you have multiple connections all firing data around, you can approach that bandwidth or 4 gigs/s.
So: if you're pushing huge arrays of data around not very often, 10 GbE will be much faster, but if you're throwing a zillion smaller sized messages to lots of different hosts at once, you will definatly get some usage out of that trunk. At least, this is how I understand it. -Jack Carrozzo On 7/3/07, Steve Cousins <[EMAIL PROTECTED]> wrote:
We are purchasing a NAS NFS server for our cluster and I'm wondering if a 10 GbE card would give us twice the performance than say 4 trunked 1 GbE lines. Given that the NAS itself has the performance to drive this, do any of you have real-world numbers comparing this sort of thing?
