Analysis of iSCSI target software

Abstract

We analyzed the design and performance of iSCSI storage systems, built into general purpose operating systems. Our experiments revealed that a storage system that uses specialized functions, in conjunction with the modified operating system, outperforms a storage system that only uses the standard functions provided by the operating system. However, our results also show that careful design enables the latter approach to provide a comparable performance to that of the former, in common workloads.
