In today's networking environments, the disk subsystem is a key element in determining overall system performance. The goal of this paper is to provide informative test results and performance-related information for various disk subsystems, to assist systems engineers and network administrators in making decisions on disk subsystem installation, optimization, and configuration. This white paper also provides information on using Fault Tolerance to prevent data loss, while maintaining system performance. Finally, this paper provides a section discussing the advantages and disadvantages of RAID technology. Help us improve our technical communication.
