ASK NC

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?

Unfortunately, I don't have specific information on whether the MEO PCI-E 2.5G Network Adapter supports RSS. However, I would suggest checking the manufacturer's website or contacting their customer support to confirm if the adapter supports RSS.
Alternatively, you may want to consider other 2.5G LAN cards that are known to support RSS. One option is the Aquantia AQC107 or AQC108 2.5G LAN cards, which are known to support RSS and are available from various manufacturers. Another option is the Intel X550-T2 10G LAN card, which supports both 10G and 2.5G speeds and is known to support RSS.
