In cluster file system, data distribution and load balancing become increasingly important. This paper presents a high performance run-time active block layout (RABL) mechanism which cans dynamically replicate and optimize the frequently accessed data blocks in the heterogeneous cluster file system. The works in this paper include: (1) presents a dynamic replicating and placing mechanism for the frequent...
The cluster technology can organize many cheap servers to cluster, and obtain the high performance. The traditional cluster file systems although can achieve high performance, but these systems all require to modify the software on client. This requirement make these systems can not be widely applied. This paper provides a novel high performance cluster file system with standard network file system...
In cluster file system, the meta-data represents the key information of a file. In order to make sure the safety of meta-data, the most of cluster file system write the meta-data to disk as soon as possible to suffer the possible failure of underlying facilities, such as node accidentally crash. The synchronous disk write of meta-data is a performance bottle of cluster file system. This paper presents...
