SIGCOMM2013: Leveraging Endpoint Flexibility in Data-Intensive Clusters

Network Usage is imbalanced! 
Take Facebook and Bing as example 

The distributed writing is hard, and the online distributed writing is NP-hard, to make it easy, the author assumes that:
1. Link utilizaions are stable
2. All blocks have the same size

In fact
1. Average link utilizaions are temporarily stable
2. Fixed-size large blocks write 93% of all blockes.


And the performance is faster, more balanced and improve storage balance.
