Simulation Study of iSCSI-based Storage System
نویسندگان
چکیده
iSCSI is becoming an important protocol to enable remote storage access through the ubiquitous TCP/IP network. Due to the significant shift in its transport mechanism, iSCSI-based storage system may possess different performance characteristics from the traditional storage system. Simulation offers a flexible way to study the iSCSI-based storage system. In this paper, we present a simulation work of iSCSI-based storage system based on ns2. The storage system consists of an iSCSI gateway with multiple targets, a number of storage devices that are connected to the storage router through FC-AL and clients, which access the target through iSCSI protocol. We present the system model, the implementation of the components, the validation of the model and performance evaluation based on the model. Coupled with the rich TCP/IP support from ns2, the simulation components can be effortlessly used for the performance and alternatives study of iSCSI-based storage systems, applications in broad configurations.

An Efficient Data Sharing Scheme for iSCSI-Based File Systems
iSCSI is an emerging transport protocol for transmitting SCSI storage I/O commands and data blocks over TCP/IP networks. It allows storage devices to be shared by multiple network hosts. A fundamental problem is how to enable consistent and efficient data sharing in iSCSI-based environments. In this paper, we propose a suite of data sharing schemes for iSCSI-based file systems and use ext2 as a...
