Hi all,

 

I'm trying to find info on the best setup for unraid and lacp with a managed switch, I have tried balance-rr and 802

802.3ad Link Aggregation (LACP)
Will give up multiple links for higher throughout (if clients and server can handle it) and will auto handle link failures

Your managed switch will need to support LACP for the Link-Agg signalling

HTH

I have a TP-Link TL SG2008 Smart switch which does support LACP but not sure what are the best settings to use

From looking at the manual for the SG2008, it’s fairly straight forward (I have one of these but it’s unused now)

GUI Menu
Switching -> LAG -> LACP
Select the ports you want to use
Leave Admin Key alone
Change mode to Active
Enable LACP on the port
Save Config
Done

I have had that settings for a long time  but when I check unraid it shows the (LACP rate: Slow) and I only copy files via network at 30-45mbps

Can you show me a screenshot of the “LACP rate:slow”?

A single copy won’t be able to use more than a single link.

That being said, what’s your UnRaid config look like? There may be a disk bottleneck going on

Please attach diagnostics, suspect same bottleneck as @miniwalks but need more data.

For balance-rr you will only see greater than 1Gbit with a Linux client - it will not work in Windows except for Windows Server.  Also, even with Linux you will suffer throughput issues with smb transfers due to the out of order packets and the congestion control kicking in.  NFS is better and I can get 2Gbit transfer speeds.  It needs switch support - trunking/link aggregation.  Mode 4/802.3ad I believe will not get you faster than 1Gbit on a single copy/transfer, but you can have multiple 1Gbit transfers taking place depending on the number of members in the group.  Infiniband/2.5/5/10G Ethernet is about the only real way to get faster than 1Gbit with Windows.

1 of my drives says its SATA Version is:  SATA 3.1, 6.0 Gb/s  but  -> (current: 3.0 Gb/s) any idea why this would be?

 

Attached in of the network settings

Possibly a bad cable?

Can you please post diagnostics to the thread for review

Cheers

What diagnostics do you want? where do I do it?

hi  I  trying to get Lacp to work with unraid and my srw2006 switch.

I set  the switch to 5 ports and check LACP for each one..  so they set

and when I set unraid to bonding 4 for link aggression  im locked out of unraid..  it cant get a ip address  just 169..

so to fix I gotta pull the usb stick  ending the network.cfg and change bonding to 0  from 4  

so I can re access it..  but what you gotta do to to get the link aggression to work
