Guozhang, Thanks for your prompt replay. I got two 300GB SAS disks for each borker. At peak time, the produce speed for each broker is about 70MB/s. Apparently, this speed is already restricted by network. While, the consume speed is lower for some topics are consumed by more than one group. Under this circumstance, if the peak time lasts for hours, my disks will be fully used.
