Hi Peter,

The bandwidth in dm-band is determined by the proportion of the processing time of each device's tokens(I/Os) to the processing time of all device's tokens(I/Os). The processing time of one token(I/O) is determined by one I/O cycle include seek latency, interrupt latency, etc...
Thanks, Ryo Tsuruta <ryov@valinux.co.jp>
