Abstract

In recent years advances in computational speed have been the main focus of research and development in high performance computing. In comparison, the improvement in I/O performance has been modest. Faster processing speeds have created a need for faster I/O as well as for the storage and retrieval of vast amounts of data. The technology needed to develop these mass storage systems exists today. Robotic storage libraries are vital components of such systems. However, they normally exhibit high latency and long transmission times. We analyze the performance of robotic storage libraries and study striping as a technique for improving response time. Although striping has been extensively studied in the content of disk arrays, the architectural differences between robotic storage libraries and arrays of disks suggest that a separate study of striping techniques in such libraries would be beneficial.
