ProCruve LACP to Linux
I am wondering if you can help me with a problem, we have a ProCrurve Switch (ProCurve J4899B Switch 2650) Running firmware H.08.83 and am trying to get a LACP Port Trunk working between this and a Linux server. At the moment I have the trunk up and running but I cannot however see an increased performance, a single port seems to be preferred without the second port being used even when the first is maxed out to its full speed.
The Linux side of the trunk is running in LACP mode and there seem to be no errors reported by each side. I am wondering if there is some option that may have been missed to utilize both links fully rather than a fail-over system.
If I can provide any more information please let me know what you require.

Re: ProCruve LACP to Linux
I keep meaning to look to see if any switches have similar capabilities but haven't gotten around to it :(
If you need a single connection/flow/stream to go faster than trunking isn't the way to go - you need to upgrade to a faster link - eg from 100BT to 1G or from 1G to 10G.

Re: ProCruve LACP to Linux
You are definitely scating on thin ice, and I suspect that if you were to do a bit of netperf benchmarking you would find that the service demand for the RR stuff at 200Mbit/s is rather higher per KB transferred than a 100 Mbit/s stream through some other scheduling algorithm.
There are some reasonably inexpensive GbE switches in the ProCurve line these days, and GbE NICs aren't all that expensive now, so do consider an upgrade to gigabit ASAP
