Abstract(in English) | IP-SAN and iSCSI are expected to remedy the problems of Fibre Channel-based SAN. iSCSI has a structure of multilayer protocols. A typical configuration of the protocols to realize this system is as follows : SCSI over iSCSI over TCP/IP over Ethernet. Thus, in order to improve the performance of the system, it is necessary to precisely analyze the complicated behavior of each layer. We proposed an IP-SAN analysis tool that monitors each of these layers, and constructed the first implementation which could not support file systems but support only raw devices. In this paper, we propose an integrated trace system which can also monitor behaviors of file systems, and introduce the implementation of the proposed system. In addition, we present the measured file access performances on the iSCSI network storage. It is obtained that network latency and file sizes do not have very large impact on file access performances in the case of not using the journaling system. On the other hand, the sizes of files have large impact on the performances in the case of using the journaling system. |
