V. Optical Mass Storage System

Experimental analysis of a mass storage system

Mass storage systems (MSSs) play a key role in data-intensive parallel computing. Most contemporary MSSs are implemented as redundant arrays of independent/inexpensive disks (RAID) in which commodity disks are tied together with proprietary controller hardware. The performance of such systems can be difficult to predict because most internal details of the controller behavior are not public. We...

Optical CDMA system using bacteriorhodopsin for optical data storage

An optical CDMA (code division multiple access) system for the optical data storage using bacteriorhodopsin (BR) is reported as an application of the BR materials. The desired signal of multiple input can be recorded and reconstructed by use of orthogonal codes. An experimental setup is proposed and demonstrated.

OPTICAL ABSORPTION IN Ce0 -V 0 EVAPORATE THIN FILMS

In this work, the optical absorption near the fundamental absorption edge of co-evaporated Ce0 -V20 films is studied. It is found that the fundamental optical absorption in these materials is sharp more like that expected for crystals. It is also found that as the V O content increases, the edge becomes less sharp and shifts towards higher wavelengths

Mass storage support for a parallelizing compilation system

Online Data Compression in a Mass Storage File System

A Unix based mass storage le system which provides access to the stored data only through the ftp protocol has provided the incentive to examine the performance of inserting an online data compression algorithm at each client in order to increase the eeective capacity of the storage system. Two online compression algorithms were tested, namely the Ziv-Lempel (gzip) and LZW (compress) algorithms...
