Design of computer network security storage system based on cloud computing technology

Nowadays, computer networks are widely used. Besides the convenience, people also feel the pressure of network viruses and hackers. At present, in the process of fighting against network security threats, traditional defense measures have been difficult to meet. Therefore, in order to meet the needs of computer network security under cloud computing technology, and for the future of cloud computing high-quality network storage system can be gradually optimized. In this paper, from the cloud computing and network security storage system two aspects of the computer network security storage performance analysis and design; Then from the design framework, through careful design, to ensure the reliability and security of data upload, storage.

The Management Strategy of Metadata in Large-scale Network Storage System

The wan Internet storage system based on Distributed Hash Table uses fully distributed data and metadata management, and constructs an extensible and efficient mass storage system for the application based on Internet. However, such systems work in highly dynamic environments, and the frequent entry and exit of nodes will lead to huge communication costs. Therefore, this paper proposes a new hierarchical metadata routing management mechanism based on DHT, which makes full use of the node stabilization point to reduce the maintenance overhead of the overlay. Analysis shows that the algorithm can effectively improve efficiency and enhance stability.

The Design and Implementation of Intelligent High-Speed Disk Storage Protocols

In this paper, through the analysis of the redundant array of independent disks system (RAID), storage area network system (SAN), network storage system (NAS), based on RAID on the system FPGA is used to design a set of intelligent high speed disk storage protocol, through the test and analysis can meet the continuous data acquisition, the real-time data storage needs, in the software through providing high access speed increases memory buffer, large storage capacity and higher data security.

Study on Object-Storage System Metadata Load Balancing

The explosive growth of information to promote the development and evolution of the network storage system structure, object-storage system came into being, the object-based storage system stores the data in a storage device with intelligent in Object-based Storage Device, and the use of the metadata server to manage the metadata, but when the metadata access amount is very large, there is a potential performance bottleneck exist in MDS, so metadata server load balancing is very important, this paper studies the metadata server load balancing technology, proposed a dynamic equilibrium strategy based on permissions.

ISCSI Network Storage System Based on Android System

In this article we extend the application of ISCSI protocol to the data storage field of mobile device. First of all, we describe the implement principles and advantages of ISCSI protocol, and discuss the problems and solutions in the design. Then we implement the interface design based on the Android platform, port the ISCSI kernel-mode module, and design the ISCSI communication interface for multiple layers of Adroid system. After that we propose a local cache policy based on the linear mapping method of Device mapper. At last, we analyze the impact of the cache policy on the improvement of system performance according to the experiment results. In a word, we supply a feasible storage solution to solve the problem that there is not enough storage capacity in the mobile device and satisfy the instant accesses from users.
