Title Proper : PERFORMANCE ANALYSIS AND MODELING OF DISK UO SUBSYSTEM IN HIGH THROUGHPUT SERVERS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : While processor speeds are rapidly increasing, the InputIOutput (I/O) especially disk I/Ospeeds are lagging far behind. The implication of this trend is that the performance ofseveral high throughput networking application servers is limited by I/O subsystemoverheads. This thesis considers three I/O subsystem configurations for high throughputservers: single disk, disk array, and Redundant Array of Inexpensive Disks (RAID). Inaddition, we consider two disk I/O scheduling policies: First-Come First-Served (FCFS)and Shortest Position Time First (SPTF) with and without prefetching. We characterizethe high throughput server workloads in terms of three categories: SequentiallyDistributed Strides Accesses (SDSA), Widely Distributed Strides Accesses (WDSA) andNarrowly Distributed Strides Accesses (NDSA). Using this characterization, we employtrace-driven simulation to compare the alternative....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
