So if I get you right and extrapolate with the replication documentation page, can I say that on a 2 nodes cluster, with a bucket set to N=3 and W=ALL, my writes would be written 3 times to disk? (and with no guarantee to be on different nodes)? thanks! On Wed, Jun 26, 2013 at 8:17 PM, Mark Phill

Hi, Louis-Philippe. With a 2-node cluster and N=3, each value will be written to disk a total of three times: twice on one node, once on the other. (The W setting has no effect on the number of copies made or hosts used.) That behavior might seem a bit strange, but it's a strange configuration

so would it make more sense to have the N=2? I'd like to be on the safe side, after reading "There are no guarantees that the three replicas will go to three separate physical nodes" in the replication docs I started to worry about the reliability of a 2 nodes N=2 setting. On Fri, Jun 28, 2013 at
