Hello,

Looking at setting up a new CEPH Cluster, starting with the following.

3 x CEPH OSD Servers

Each Server:

20Gbps Network
12 OSD's
SSD Journal

Looking at running with replication of 2, will there be any issues using 3 
nodes with a replication of two, this should "technically" give me ½ the 
available total capacity of the 3 node's?

Will the CRUSH map automaticly setup each 12 OSD's as a separate group, so that 
the two replicated objects are put on separate OSD servers?

Thanks,
Ashley
