Digimer, Thanks for your reply.
I come up with the number 300M from DRBD official website "A good rule of thumb for this value(rate parameter) is to use about 30% of the available replication bandwidth. ". I use 10G Ethernet card for replication traffic, 1024M * 0.3 is 300M. What wrong with my calculation?
