Title: Storage Systems Then And Now

Host: Abhishek Bhattacharjee

Abstract:

Storage technology has undergone rapid change in the past years. For many decades, hard disk drives were the dominant medium; then, Flash-based systems came into existence and started to dominate in some regimes (e.g., where performance was critical). Now, a proliferation of new technologies, often called “persistent memories”, are threatening to redefine the storage landscape even further. In this talk, I will examine these technology trends, and discuss how storage systems will change to accommodate them. I will also focus on aspects of storage that will likely stay the same, regardless of technology.
