Correct me if I'm wrong, but the sole cost of storing 300TB on AWS will account for roughly 300000*0.10*12 = 360000 USD per annum.
We operate a cluster with 112 nodes offering 800+ TB of raw HDFS capacity and the CAPEX was less than 700k USD, if you ask me there is no comparison possible if you have the datacenter space to host your machines. Do you really need 10Gbe? We're quite happy with 1Gbe will no over-subscription. Mathias.
