Hi there.

A few days ago I took delivery of a new QNAP nas box with 4 lan ports on the back, so I configured these for LACP along with my server.

My question is I have 2 ports LACP on my server, 3 ports on my NAS, and my managed switch I think configured as it should be as if I configure it any other way than LACP I cant ping the devices.

Should I be realistically able to get more than a sustained 113mb/s??

I can see form my server and NAS that I am maxing out only 1 port of the team.

Is there any way to get this higher??? I have 6TB of data to move and its taking ages lol.
 
That isn't how LACP works. Link aggregation is for redundancy or for use by a server with a bunch of clients.

You might see a bit more utilization if you run multiple sessions, but don't expect with what you're doing to get more than one gigabit.

If you want real speed start looking at 10gb or better. I'm running 56gb infiniband in our HPC clusters. Is there a PCIE slot in your NAS? I picked up a couple of used two port 10gb NICs with SFPs for $30 each last week for home.

Anyone know if QNAP supports bonding?
 
From QNAP's page on port trunking:

"Port Trunking cannot break the speed limit of a single Ethernet device, but it offers a sufficient amount of bandwidth for multiple users connecting at the same time. For example, if two 1Gb NICs are used for Port Trunking, the aggregated network bandwidth will be increased to 2Gb, but the network speed will remain 1Gb.

I guessed as much. Just thought I'd ask. And no it doesn't have an expansion slot.

Just have to do it the old fashioned way and wait. I started the move shortly after I posted anyway. 13 more hours to go. Wipe off hyper-v, load esxi and start the copy back the other direction
 
If both server and QNAP support SMB version 3. You can do multiple copy streams by splitting up the copy process and take advantage of LACP of the QNAP

I'm in the process of moving 100's of TB at work using robocopy. I've broken up jobs by running multiple robocopy session on same server.
 
I once setup trunking (2 x 1 gb) of broadcom adapters in an older Dell server. While one guy pulling a file didn't look any different, 2 other guys could pull another file and it went by about 50% faster.
