Facebook Inc (NASDAQ:FB) has now brought a new concept of “Pods”. Before it, the company was using racks in the cluster architecture. The article quoted Facebook Inc (NASDAQ:FB)’s director of Network Engineering, Najam Ahmed, who has recently explained why the company was so frantically searching for an alternative to the cluster-rack approach. Ahmed said that Facebook Inc (NASDAQ:FB)’s experts were always searching for some vertically integrated, large-chassis-based box architecture where the space can ben ever ending. They were tired of adding more and more racks to the clusters. Buying the biggest switch that is available was the last option, which was, years ago, used by Facebook Inc (NASDAQ:FB) and now experts were scratching their heads.

In the pods approach, Facebook Inc (NASDAQ:FB) can add as many fabrics of data cluster as needed without worrying about bandwidth and space. Ahmed said that Facebook Inc (NASDAQ:FB) is focusing more on power efficiency of the data architecture. He said that the company measures the performance of the data center architecture in terms of megawatts of power. Bottom up SDN approach is the future and Facebook Inc (NASDAQ:FB) is trying to convince the vendors to adapt the emerging trends.

The source said that Facebook Inc (NASDAQ:FB) has opted for this design in order to facilitate application development and app speeds. Line-rate performance is a key factor that will be improved after the introduction of pods.
