July 20, 20178 yr Author Well i'm dumb to say the least that transfer speed was between two mechanical drives (WD red in my unraid box to a WD green in my windows machine) but however just transferred from my WD green to my cache in unraid and saw about 400 mb/s still seems a little low for a 10gb connection....

Id recommend looking at running iperf to test line speed, samba and unraid has some overhead to it. https://elkano.org/blog/testing-10g-network-iperf/ Tim
July 20, 20178 yr Author alright to adjust this on the unraid side and sorry if this is a dumb question but do i just SSH into the unraid machine? still kinda new to unraid so was not sure if they're is a terminal built into unraid that im missing somewhere...

July 20, 20178 yr Author Yes I am using windows and I have putty... Another thing I was wondering about is if you can use the mellanox mlxup firmware tool within a putty SSH to the unraid machine...

Another thing I was wondering about is if you can use the mellanox mlxup firmware tool within a putty SSH to the unraid machine... nope, you can try but there are a lot of libraries that are missing because unraid is a stripped down version of linux.
July 20, 20178 yr Author so then if i wanted to update the mellanox card in that unraid machine would i essentially have to pull it out of that pc and put it into another one to perform a firmware upgrade?
