Blockchain, with its characteristics of non-tamperability and decentralization, has had a profound impact on various fields society set off boom in the research application blockchain technology. However, technology faces problem data availability attacks during application, which greatly limits scope domain applications. One most advantageous researches to address this is scalable solution tha...

Abstract - One of the important problems in grid environments is data replication in grid sites. Reliability and availability of data replication in some cases is considered low. To separate sites with high reliability and high availability of sites with low availability and low reliability, clustering can be used. In this study, the data grid dynamically evaluate and predict the condition of t...

This paper examines how server marketing claims of high reliability (e.g., 99.999%) stack up against real world data measurements. Our goals were to: measure discretionary NFS data availability, compare data availability between standalone and clustered systems, and draw some conclusions about best practices for customers. We explain our methodology for measuring, filtering, and categorizing av...
