Abstract


NAS high-availability cluster architecture based on the analysis of the NAS high availability cluster key technology , in-depth study , the contents of a single system image technology . The preliminary design of the prototype of a high - availability cluster system in a two-node NAS , while the system has good scalability . The primary problem faced in the design of the high-availability NAS cluster system is the architecture of the system . Analysis of the basic principles of traditional NAS cluster solution architecture , establish a high-performance NAS cluster solution model . Its users with decentralized services , centralized management of the global source data , play to their respective advantages of decentralized and centralized , and the realization of the principle discussed in detail . A single system image technology is one of the key technologies of NAS high-availability cluster NAS cluster is mainly used for data storage , I / O performance in a single system image technology is the key . Description of the services provided by a single system image , single file hierarchy technical solutions to achieve a single I / O space , a single entry point , are discussed in detail . NAS cluster high availability system software is the core part of the entire the NAS high availability cluster system . The system software is designed and implemented in the Windows NT system environment , the form of its core services under WindowsNT system . Through a series of monitoring agents , monitoring system status . The whole system fully automated failover . Applications running on a node failure , the system in a very short time to be automatically transferred to another node .
