Towards Transactional Load over XtreemFS

چکیده
We evaluate the performance of distributed file systems (DFS) under the IO load produced by enterprise applications. The evaluation is carried out using a trace-based approach that allows for recording file system accesses of an application and re-playing the trace on an arbitrary file systems under test. This method avoids the overhead that is associated with installing and maintaining complex multi-tier enterprise applications. Our trace-based assessment suggests that DFS, and specifically XtreemFS have a good potential to support transactional IO load in distributed environments: they demonstrate good performance of read operations and scalability in general, while at the same time opening the way for significant TCO reduction. We found, however, that more work should be done to improve the performance of write operations, which is crucial in transactional enterprise applications.

The XtreemFS Architecture
This paper describes the architecture of XtreemFS, a federated and globally distributed file system. XtreemFS has to cope with scalability problems, a huge number of clients connected over WANs, the related high latency and security problems, as well as distributed file data and metadata. The XtreemFS architecture solves performance, scalability and grid-related problems by a novel design combi...
متن کاملTowards Load Balanced Distributed Transactional Memory
We consider the problem of implementing transactional memory in d-dimensional mesh networks. We present and analyze MultiBend, a novel load balanced directory-based protocol, which is designed for the data-flow distributed implementation of software transactional memory. It supports three basic operations, publish, lookup, and move, on a shared object. A pleasing aspect of MultiBend is that it ...
متن کاملXtreemFS : A File System for the Cloud
Cloud computing poses new challenges to data storage. While cloud providers use shared distributed hardware, which is inherently unreliable and insecure, cloud users expect their data to be safely and securely stored, available at any time, and accessible in the same way as their locally stored data. In this chapter, the authors present XtreemFS, a file system for the cloud. XtreemFS reconciles...
