We are in the process of analyzing our options for the future purchases of our Hadoop/HBase DN/RS servers. Currently, we purchase Dell PowerEdge R710's which work well for us. However, we know that there are other options that may give us more bang for our buck.
I'm not as interested in knowing the specs of the machines that people are using. Rather, I'm curious to know where you buy them from or if you are building them yourselves. Any feedback on how you acquire server hardware in your environment would be greatly appreciated. Jason
