Scenario
A newer NAS and clients support SMB multichannel, but transfer speeds remain no better than a single link.
Recommended Resolution Path
- Verify the NICs, switch path, and client adapters actually qualify for multichannel.
- Check whether RSS, RDMA, or teaming settings are supported and enabled correctly.
- Run tests that prove whether the workload is network-bound or storage-bound.
- If the hardware cannot really benefit, document that to avoid cargo-cult tuning.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
