Title: “Next-Generation Storage Systems for Big Data”

Talking Points:

How to efficiently manage current emerging storage devices
How to design a new DNA storage system
How to build a high-performance storage system for big-data applications

Abstract
Tremendous technology developments have been witnessed in the area of computing, network and storage systems. A huge amount of digital data was generated in the past decades with the rapid growth of new technology development such Internet of Things (IoT) devices, edge devices, sensors, 5G, and so forth. Such vast amounts of digital data are being generated and are available for access to all new applications. It becomes a critical and increasing challenge to manage this huge amount of data available at our fingertips and to locate the information that we need at anytime from anywhere.

In this talk, I will focus on emerging storage systems for big data from two perspectives. First, from the capacity perspective, two emerging storage devices/systems with large areal densities (i.e., shingled magnetic recording (SMR) and DNA storage) are introduced including their management and utilization. For SMR, based on its unique properties, we introduce a Machine Learning (ML) based scheme to improve the performance of the SMR storage system. Moreover, for image-based applications, we will introduce how to efficiently store images into DNA storage with higher reliability and capacity. Secondly, from the performance perspective, I will present a high-performance system to accelerate graph neural networks (GNNs). The system is co-designed with the storage systems and algorithms in GNNs and finally can significantly speed up the training process of GNNs.
