Abstract


Along with the computer and Internet technology developing rapidly and the process of informatization boosting, data intensive application constantly emerging in large numbers. Huge demand of data storage promoted the development of computer storage technology. The simple isolated storage equipment such as Tape, disk and RAID faced a serious challenge. Storage system should not only has high access speed, but also can effectively use heterogeneous storage resources to construct the mass storage capacity. Using network to establish storage system and seek innovation and breakthrough in storage technology is a best choice.On the basic of deeply rearching in network storage technologies and some popular distributed file systems , we not only absorbed their advantages but also pointed out their problems, and put forward our intelligent network storage system (INSS) architecture. INSS adopts a kind of fusion INSS network storage system, in reference to traditional network storage system and distributed file system. Moer over, makes some optimization and improvement.My paper rearched the related technology research and design in storage nodes module of INSS storage system, and mainly studies some key technologies including the following aspects:1. Design of storage nodes and management node data structure , including management node election and backup strategy.2. Storage Virtualization of storage nodes. It offering the basic storage space for hole system with a liner and Transparent free space.3. Design and implement the storage nodes heartbeat algorithm named sliding windows accelerate heartbeat algorithm.4. Design and implement the high-speed storage nodes Cache mechanism.Experiments in performance show that virtualization of equipment for the entire system has obviously improve the management of storage space. The heartbeat algorithm reduced system failure and improved the reliability of system. Cache mechanism in storage nodes increased access rate, this means the characteristics of high performance.
