Thinking along the lines of the approach of many 1U by 4 drive host (as above) with no hardware RAID... what are the thoughts between SATAII (3G/s) vs SATAIII (6G/s) and on 1G Ethernet versus 10G Ethernet. - Steve P.S. I will be assuming a replication level of 3 copies and would probably be looking at 10 nodes or less initially. Maybe populating with 6 drives instead of 4 (if I can find the right chassis). -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
