Storage Systems
This course on Storage Systems focuses on the design and implementation of persistent storage systems. It begins with an introduction to the fundamental building blocks of modern storage hardware, including magnetic hard disk drives (HDDs) and solid-state drives (SSDs), as well as their organization into RAID systems for reliability and performance. Building on this foundation, the course explores the structure of the Unix/Linux I/O stack and examines how storage is managed across local, networked, and parallel file systems.
The course then delves into advanced techniques used in large-scale storage systems, including key-value stores, persistent memory technologies, and methods for improving efficiency and performance. Topics such as deduplication, delta encoding, secure auditing, and systems like LOCKSS are discussed in the context of real-world applications. The lectures are designed to be self-contained, requiring no additional materials beyond the recommended references, while offering a comprehensive overview of modern storage system design and optimization.

The lecture slides are accessible to registered students of this course directly via this LMS. For legal reasons, the literature links are often only accessible from within the network of Saarland University, for example via a VPN. The lectures take place in Building E1 1 in Seminar Room 106
