lukeoslavia Posted July 6, 2023 Share Posted July 6, 2023 (edited) I am trying to setup SMB multichannel, potentially with RSS as well, between my unraid NAS and my windows server 2022. I have tried several configurations but I just cannot seem to get a connection to the unraid share with multichannel. Both machines are DL360 Gen9's. The nas has 64gb ram and the windows machine 192gb ram and the processors are different models, but other than that specs are equal. Unraid is version 6.12.2. What I've tried so far: Windows configuration: 4x 1gbe ports in a NIC team (LACP / 802.3ad) Verified multichannel is enabled Verified the nic team has RSS enabled Checked that the interface throughput is 4gbps Ignore the first result, I disabled and re-enabled RSS as an attempted fix... Unraid config: I have tried all 4 of the ethernet ports separated and then added to the SMB extra commands: server multi channel support = yes aio read size = 1 aio write size = 1 interfaces = "10.10.30.1;capability=RSS,speed=1000000000" "10.10.30.2;capability=RSS,speed=1000000000" "10.10.30.3;capability=RSS,speed=1000000000" "10.10.30.4;capability=RSS,speed=1000000000" This didn't work, I got no additional throughput and wasn't able to copy multiple items at 1gbps even. I tried also just enabling Multichannel in the smb settings dropdown without any additional config with the same result. Current and closet to a good result config: SMB multichannel enabled in the smb settings dropdown. All 4 ethernet ports in an 802.3ad bond (LACP / Mode 4) With this setting I cannot get a multichannel SMB copy, but I installed the openspeedtest docker to test throughout the process and with this configuration I am getting 1gbps download speed and 3 - 3.5gbps upload. Super odd that it isn't full duplex this way!? This is where I currently am. I am not sure if multichannel is not currently working in unraid, or if I am configuring something wrong, but if anyone could help me get this going better I would greatly appreciate it!

cholzer Posted September 4, 2023 Share Posted September 4, 2023 (edited) @jonp can you tell us the current state of SMB Multichannel? Did anything change since this blog post? https://unraid.net/blog/how-to-beta-test-smb-multi-channel-support Edited September 4, 2023 by cholzer Quote Link to comment
