ProCurve 2910-al - LACP config for max speed

[roman_sputnik]

Hi all

I'm trying to configure Link Aggregation (LACP) on the ProCurve 2910-al switch to increase file read/write speeds via the network and was looking for some advice on configuring this. 

The workstations are a mixture of Mac Pros and high-end PC with Dual NIC. Each connected to the switch with two cat5e cables. The server is connected to the switch via a 10Gbe backplane and this connection is fast indeed. 

I have enabled LACP on the switch and configured the computers so that hey have a single IP, etc. however the speed did not increase at all, i.e. it's almost the same as with single port connected to 1Gbe port. ~80MBps read/~60MBps write.

I'm getting confused with Trunk Types and Groups, LACP Status and Flow Control settings. The manual is somewhat confusing and I can't figure out best options for these specific requirements.

Possible options are: 

* Mode: currently Auto (10HDx, 100HDx, 10FDx, 100FDx, Auto, Auto-10, Auto-100, Auto-1000, Auto-10-100)

* Flow Control: currently Enable (Enable, Disable)

* LACP Status: currently Active (Disabled, Active, Passive)

* Trunk Type: currently None (None, Trunk, LACP)

* Trunk Group: currently None (None, Trk1-Trk60)

* Broadcast Limit (0-99): currently 0.

Has anyone had any luck increasing the network speeds by tweaking the LACP? If so, I'd highly appreciate your advice or feedback!

You config is probably fine, but remember how hashing over link-aggregation works. One flow won't utilize both links, but only one of them at the time. You must use multiple sessions to utilize the aggregation fully.
