As the latest development of the distributed storage technology, Cloud storage is the product of the integration of distributed storage and virtual technologies. Cloud storage is a method that allows you to use storage facilities available on the Internet. Relative to the current Commercial cloud storage file systems, introducing P2P network of interest groups put forward the idea of a P2P model based...
With the information and network technology, rapid development, rapid increase in the size of the data center, energy consumption in the proportion of IT spending rising. In the great green environment many companies are eyeing the green store, hoping thereby to reduce the energy storage system. Data de-duplication technology to optimize the storage system can greatly reduce the amount of data, thereby...
Managing data growth continues to be the biggest challenge for IT. And tiered storage, a solid way to Information Lifecycle Management (ILM), is very helpful to reduce the cost and improve the storage efficiency in data center. However, data migration is the primary challenge to implement tiered storage management, and it's hard to be resolved by traditional data migration solutions, which are mainly...
In order to meet the need of data disaster tolerance in low end application, this paper discusses some flaws of already existing replication protocols based on storage replication system. Then a casual ordering replication protocol (CORP) is presented in the paper aiming at resolving these flaws. Furthermore, the paper discusses the workflow of CORP and provides a timestamp method to implement CORP...
In this paper, we present the design and evaluation of PeerCSDB. It is a database management system in P2P networks. It uses a structured P2P network to manage copies of data cache, and an unstructured P2P network to manage peers who are responsible for the data cache. It has the benefit of the Client/Server model and peer-to-peer model at the same time. PeerCSDB distinguishes itself from existing...
One research question crucial to RFID technology's wider adoption is how to efficiently transform sequences of RFID readings into meaningful business events. Contrary to traditional events, RFID readings are usually of high volume and velocity, and have the attributes representing their reading objects, occurrence times and spots. Based on these characteristics and the non-deterministic finite automata...
