Configuring Multichannel
Multichannel, or UMC, enables the capability to divide a 10Gb port into multiple
physical functions, with flexible bandwidth capacity allocation, that appear to the
operating system and network as separate physical devices.
Multichannel can be configured on OCe14000-series adapters through the adapter BIOS
or the OneCommand Manager application.
To configure multichannel using the adapter BIOS, see the Boot for NIC, iSCSI,
FCoE, and RoCE Protocols User Manual.
