Design and implementation of a fibre channel network driver for SAN-attached RAID controllers

Abstract

Fibre channel SAN (storage area network) is considered to be a promising solution to address storage problems caused by the sheer volume of data and their management. To adopt this new storage environment, we design and implement a high performance fibre channel network driver for SAN-attached RAID controllers in a real-time operating system. We describe the architecture of the fibre channel driver which consists of two modes; a target mode and an initiator mode. An exception handling mechanism for enduring a disk failure is also given. Lastly, we measured the performance of the fibre channel driver. Testing results reveal a moderately successful performance of the fibre channel driver.
