In Cloud Storage system, storage systems have to service for large numbers of scattered data access nodes, and data I/O almost are in random access form, in addition, the distribution storage of data result in data transmission between the Cloud nodes increases greatly, then the performance of the cloud storage system was be restricted remarkably. In this paper, we put forward a system for improving...
The file system for the Cloud Storage usually use the distributed structure which store the metadata and the user data respectively. The I/O nodes get the management information of file from the specific metadata server through the networks. Under this mode, the metadata server should be the performance bottleneck of the whole system when huge number nodes or the heavy workloads in Cloud Storage....
IB network as a new network technology, in many areas has been rapid development. In the mass storage system, the network will serve as a link compute nodes and storage nodes in the task, while the IB network in high-performance systems are gradually popular. In this paper, test new high-speed InfiniBand network into FC testing methods, and proved by experiments that the method is feasible and reasonable...
The aim of autonomic computing is to realize self - management of complex IT systems, which makes systems own the ability of self-configuration, self-recovering, self-optimizing and self-protecting. The aim of cloud computing is to realize the use of resources on demand in distributed environment. But the problem of how to build an autonomic computing model for cloud computing environment has not...
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...
LZpack is a general file system benchmark tool conforming to POSIX.1. It provides an effective method to evaluate different file systems. It also offers reliable data to the developers who use POSIX.1 file system API to design applications. With the cluster testing structure, LZpack can make precise evaluations of file IO performance and file system metadata operation performance. This paper not only...
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...
