I guess you are looking for a way to evaluate how you can load data in data center. If it is the case, please refer to Cisco's Book : "Data Center Fundamentals". It outlines a set of metrics to consider for data load balancing data.

Hope it helps to answer your question.

thank you for your reply

indeed I have optimal data placement algorithm of data in a set of data center, and I'm looking tools, test database to assess the performance of my algorithm

I am not sure if this tool would be helpful or not : http://www.ixiacom.com/products/racksim

Have a look also at this paper : http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6664409

Otherwise, let me know if you need any research paper (IEEE, ACM, Elsevier, etc.) and I will send it to you.
