SMB Multichannel

SMB Multichannel supports establishing a single SMB session over multiple network connections.

SMB Multichannel is a feature of the SMB 3.0 protocol that provides the following capabilities:

Increased throughput
OneFS can transmit more data to a client through multiple connections over high speed network adapters or over multiple network adapters.
Connection failure tolerance
When an SMB Multichannel session is established over multiple network connections, the session is not lost if one of the connections has a network fault, which enables the client to continue to work.
Automatic discovery
SMB Multichannel automatically discovers supported hardware configurations on the client that have multiple available network paths and then negotiates and establishes a session over multiple network connections. You are not required to install components, roles, role services, or features.
