Hi Smaine, There is always an overhead of running multiple flume instances, i.e. multiple Java VMs. Thus, I wouldn't recommend running more of them if that's not due to distribution across servers.
But, you are able to do round-robin events from source into multiple channels and those channels could have one disk per channel. However, in that case you'll also need at least one sink per channel. Guess that's even desirable if you're sinking your data into the HDFS.
