Storage Systems

Storage Systems. Instructor: Dr. K. Gopinath, Department of Computer Science and Automation, IISc Bangalore. The objective of this course is to discuss storage systems, their design and analysis from both hardware (architectural features) and system software (operating systems, networking, run-time systems) point of view.
