SMB Multichannel requirements

You must meet software and NIC configuration requirements to support SMB Multichannel on a cluster.

OneFS can only support SMB Multichannel when the following software requirements are met:

Windows Server 2012, 2012 R2 or Windows 8, 8.1 clients
SMB Multichannel must be enabled on both the cluster and the Windows client computer. It is enabled on the cluster by default.

SMB Multichannel establishes a single SMB session over multiple network connections only on supported network interface card (NIC) configurations. SMB Multichannel requires at least one of the following NIC configurations on the client computer:

Two or more network interface cards.
One or more network interface cards that support Receive Side Scaling (RSS).
One or more network interface cards configured with link aggregation. Link aggregation enables you to combine the bandwidth of multiple NICs on a node into a single logical interface.
