Hi, Josh:
Thanks for your reply. However, I had asked a question about replica setting

http://www.spinics.net/lists/ceph-devel/msg07346.html

then that means the total io throughputs on hard disk is over 3 * n MB/s.
Because I

Osd.0 ~ osd.11 is on server1
Osd.12 ~ osd.23 is on server2
Mon.0 is on server1
Mon.1 is on server2

I have updated the how-to here:

And published the results of my latest tests:

I have taken a look into teuthology, the automation of all this tests

Thanks in advance.
