Poster: Data Migration

IBM estimates that 2.5 quintillion bytes are being created every day and that 90% of the data in the world today have been created in the last two years alone. These big data come from search engines logs, social media sites, and digital media just to name a few. A large share of these data is not being kept on personal computers but in large-scale storage systems such as data centers. Data migration, a frequent and time-consuming operation in such storage systems, requires that data are moved around across thousands of disks. In this talk, I will show how the data migration problem can be modeled as a graph problem and use this model to demonstrate efficient algorithms for data migration
