I just enabled SMB Multichannel on my Synology DS918+. I already have both NICs running in as an aggregated link, so the bandwidth to/from the NAS is 2Gb/s both ways.
I enabled the beta SMB Multichannel and connected up my 2.5Gbe router and PC but only getting 1Gb/s SMB transfers.
I've narrowed this down to my onboard Intel I225-V LAN adapter not exposing receiver side scaling (RSS), which Windows needs to operate SMB multichannel.
RSS-enabled 2.5gbe LAN adapters seem to be tricky to find; even if the chipset supports it (on paper) it's often not enabled (by exposing in the driver INF file) for some reason. I notice you looked at this MEO card, which Amazon says supports RSS. Can you confirm? Otherwise, can you recommend a decent alternative that definitely does?
