Mass Storage
Abstract
While not always given the consideration it deserves in the world of high performance computing, mass storage is critical for creation of adequately performing storage subsystems with sufficient capacity for supercomputers. It encompasses a collection of technologies that make it possible to preserve a large amount of the computational state, both data and executable code, generated and consumed by applications between their invocations and after machine shutdown. The chapter discusses in detail several prevalent storage device technologies, such as hard-disk drives, solid state devices, optical drives, and magnetic tapes. Basic principles of operation are delineated for each device class, along with a few recent ...
