Modeling and design analysis of a workstation LAN server

Abstract

This papcr describes the development of a tracedriven performance model for a PS/2 token-ring file server. The target system consists of a tokcn ring network, a PS/2 file server, and several requesters. We havc dcrived a high lcvel bchavioral modcl for the server hard disk and disk cache, which enablc us to study thc scrver pcrformancc and rcquest response times under diffcrent pattcrns of network traffic and configurations. Thc model simulation results have been uscd for analyzing the design trade-off of network componcnts and for thc capacity planning and performance tuning of a LAN servcr.
