FWIW I tend to agree. There are probably some network deployments where it makes sense, but for most people I think it just adds complexity. Maybe it makes it easy to utilize dual interfaces, but my guess is you're better off bonding them if you can. Note that on a largish cluster the public/client traffic is all north-south, while the backend traffic is also mostly north-south to the top-of-rack and then east-west. I.e., within the rack, almost everything is north-south, and client and replication traffic don't look that different. sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
