For me,We have seem a supermicro machine,which is 2U with 2 CPU and 24 2.5 inch sata/sas drives,together with 2 onboard 10Gb Nic. I think it's good enough for both density and computing power.
To another end, we are also planning to evaluating small node for ceph,say a ATOM with 2 /4 disks per node,and you could have 6 nodes in a 2U space 在 2013-3-18，6:39，"Mark Nelson" <mark.nel...@inktank.com> 写道： > Hi Stas, > > The SL4500 series looks like it should be a good option for large > deployments, though you may want to consider going with the 2-node > configuration with 25 drives each.
