Anyone got SMB multichannel working on OS6?
Hi, I have old Ultra 4 Plus with OS6 6.10.8 connected on both 1Gbit ports to 2.5Gbit network switch (no teaming or bond configuration , just two separate adapters with two IP). PC is using a single ...
I made it work in OS6! I can now transfer single file with 1.7Gbit/sec from old NAS using single 2.5Gbit NIC and two NAS 1GBit NIC's. In order for multipath to work, you need two IP's on both sides: NAS and PC. If you have single NIC in PC, you need to give it two IP's. Then you need to go into Windows NIC advanced properties and enable RSS (you will need up-to-date driver for this). Then on NAS side, you need to add configuration to smb.conf:
interfaces = "192.168.0.4;speed=10000000000,capability=RSS" "192.168.0.5;speed=10000000000,capability=RSS"
server multi channel support = yes
And also add static routes to your PC (where two adresses are the two adresses of your PC NIC)
ip route add 192.168.0.222 dev eth0
ip route add 192.168.0.223 dev eth1
Reboot, check status in PowerShell with "Get-SmbMultichannelConnection" and that's it.
This is what I added to smb.conf to enable SMB multi channel:
interfaces = "192.168.0.2;speed=10000000000,capability=RSS" "192.168.0.3;speed=10000000000,capability=RSS"
server multi channel support = yes
and according to PC I do have SMB multichannel working against NAS:
PS C:\Windows\system32> Get-SmbMultichannelConnection
Server Name Selected Client IP Server IP Client Interface Index Server Interface Index Client RSS Capable Client
RDMA
