About Multichannel
Multichannel is a feature of the SMB 3.0 protocol which allows the client to bind a single session to multiple connections.
Multichannel provides the following benefits:
Increased Throughput – The file server can simultaneously transmit more data using multiple connections for high speed
network adapters or multiple network adapters.
Network Fault Tolerance – When using multiple network connections at the same time, the clients can continue to work
uninterrupted despite the loss of a network connection.
Automatic Configuration – SMB Multichannel automatically discovers the existence of multiple available network interfaces
and dynamically adds connections as required.
Multichannel can be enabled and disabled from the CLI using the command CLI > (tenant) internal protocols-
settings SMB-settings edit.
Multichannel Requirements
Multichannel requires the following:
Hardware – On both the client and the server, multichannel requires multiple NICs or a NIC configured with RSS (Receive Side
Scaling).
Operating System – FluidFS supports multichannel on Windows 8 or Windows Server 2012 and 2016.
By default, the Windows client opens one connection per non-RSS NIC and up to four connections per RSS capable NIC.
