Design and performance evaluation of a disk array controller with fibre channel interface

摘要

Storage demands are growing rapidly with the increasing usages of multimedia, stream casting, and large scale database. High-performance RAID storage is a critical component for many large-scale data-intensive applications. The goal of our project is to implement high performance external RAID controller based on Intel IOP321. The software design of the RAID controller is introduced, which consists of six functional modules: SCSI Target, Cache Management, RAID Kernel, I/O Schedule, SCSI Initiator and Global Configuration. A PC architecture RAID controller with Fibre Channel interface to host has been implemented to test algorithms and evaluate performances. We also present hardware scheme of the controller based on Intel IOP321 processor.
