Abstract


Network technology continues to evolve the ever-increasing demands on server I / O performance , improve I / O performance is the focus of the current server technology development . This study is divided into two parts: the design of a line with the the I2O specification RAID system and the system hardware module development . The significance of the research is to develop embedded I / O compatible with existing server platforms , this I / O platform not only through the use of RAID technology to improve server I / O performance , while I2O technology , greatly reduce the burden of the host-side application program processor due to I / O operations caused by addition , also based on the the I2O driver design specification mode can greatly simplify the high repeatability of driver development process . This paper focuses on two core issues discussed . The I2O specification defines and system architecture as the basis for the development of knowledge , given the realization of several typical the I2O platform of the form ; and will introduce select the I2O operating system IxWorks including characteristics of IxWorks , the services provided by first introduced , and integrated development environment Tornado , and detailed description of the cross compiler built environment steps from both hardware and software ; established a good knowledge base , given the entire I2O RAID system structural design, the definition of the various parts of the system function , and as the development of standards ; and detailed description of the system hardware module development and implementation process , including the creation of the virtual disk , set up the module parameters and parameter table array , message processing function , and cited a number of the typical sense of the function implementation details ; Finally, the installation and use of specific hardware modules , combined with RAID intermediary service module , complete implementation of the RAID function of the system as a whole , to test the I / O performance , combined with test data analysis , Reference the I2O RAID system can greatly improve the I / O performance of the entire system .
