Abstract

Direct-attached storage has historically had the reputation of being less capable than equivalently sized SAN installations. Here, we empirically demonstrate the performance achievable in multiple-terabyte, direct-attached disk subsystems. A number of parameters are explored, including file system, number of logical drives, and RAID configuration.
