Abstract


As clustering technology applications in the field of critical transaction processing results , the availability of high availability system is a system with a balance between the costs . In high-availability computer system to analyze the key technology , based on in-depth study of the high availability based on shared memory architecture of the system . Preliminary design of a service group to monitor objects iSCSI-based shared storage system prototype dual- node high availability , high availability system gives the overall design and management software management module implementation. System is designed to have good scalability. High availability system design is the most important issue facing the system architecture design . Detailed analysis of the high-availability architecture of the system and its storage interconnect technology , the establishment of an iSCSI-based high availability system architecture model . While the high-availability disk array system also ensures high availability of data . Established a Markov model for the system , the system is analyzed theoretically achievable availability . High availability high availability systems management software is the core of the system . Detailed analysis of the high-availability systems management software functionality and its key technologies . Windows2000/XP based services technology to design a two-node management software, multi-process and use the mileage between each monitor communications technology to improve software stability , the use of asynchronous input-output technology to improve the operating efficiency of the software . Gives its process division, module division and major data structures. Management software support extended to different operating system platforms and multi-node . High availability systems management software management module is used to manage high-availability system administrators a separate executable program. View data management module using separate ways, using multi-threading technology to improve operational efficiency , the use of an optimized communication protocol. Analysis of the management module technology solutions, discussed in detail the design and implementation of the management module .
