In the vSphere Client, each storage device, or LUN, is identified by several names
Runtime Name The name of the first path to the device. The runtime name is created by the
host. The runtime name is not a reliable identifier for the device, and is not
persistent.
The runtime name has the following format:
vmhba#:C#:T#:L#, where
vmhba# is the name of the storage adapter. The name refers to the physical
adapter on the host, not to the SCSI controller used by the virtual machines.
C# is the storage channel number.
Software iSCSI initiators use the channel number to show multiple paths
to the same target
Can somebody explain more about what channel number is referred here
