Measurement and inference in data centers present a set of opportunities and challenges distinct from the Internet domain. Existing tool-sets may be perturbed or be mislead by issues related to virtualization. Yet, while equally con- fronted by scale, data centers are relatively homogeneous and symmetric. We believe these may be attributes to be exploited. However, data is required to better evaluate our hypotheses. Therefore, we introduce our efforts to gather data using a single framework from which we can launch tests of our choosing. Our observations reinforce recent claims, but indicate changes in the network. They also reveal additional obfuscations stemming from virtualization.
