18-746 Storage Systems (Fall 2024)

Overview

Storage systems are among the most fascinating and the most important parts of computer systems. They often dominate the performance of a system, and failures of other components are frequently addressed by restarting from the data stored on them. Indeed, storage systems hold the crown jewels of most organizations: their information (from source code to Microsoft's software to the sales databases of every e-commerce site to the logs and indices driving the Big Data and ML revolution). There continues to be great demand for bright people and better solutions in this critical field of computer systems.

This course covers the design, implementation, and use of storage systems, from the characteristics and operation of individual storage devices to the OS, database, and networking approaches involved in tying them together and making them useful in servers and large-scale distributed systems. Along the way, we will examine several case studies of real systems, demands placed on storage systems by important applications, and impacts of trends and emerging technologies on future storage systems.

Although the word "Advanced" is no longer part of the title for this class, due to an unfortunate acronym, the class will continue to have the same advanced level of content, projects, and high-level expectations.

This class is supported in part by a AWS in Education Grant award.
