Design And Implementation Of High-speed Disk Array Storage Control System

"Cloud computing" rapid development and "cloud storage", and "cloud computing" and "cloud storage" technologies increasingly frequent updates, related applications are increasingly widespread. Traditional computer information technology industry and national information security has attracted increasing attention, high-performance storage products for a higher performance, better security, more reliable and more secure stability requirements. As a server-class storage and professional-grade storage products in the key control technology, control technology to improve disk array is extremely important.Disk interface technology after years of continuous improvement, from the early SAS SCSI interface to the current interface, data interface transfer rates and storage system performance continues to increase. Need to design a control system using a disk array for high speed interfaces to meet the requirements of high-performance storage.Brief classification of disk array technology to analyze the development of disk array technology and the common characteristics of the disk array level and application of occasions. Using the latest disk array controller design a new high-speed disk array storage control system hardware.Papers will be divided into the control module hardware system design, memory module design, PCI Express module design, SAS module design, power module design and firmware module design six main modules, complete system hardware design and testing.
