CEFT: A cost-effective, fault-tolerant parallel virtual file system
The vulnerability of computer nodes due to component failures is a critical issue for cluster-based file systems. This paper studies the development and deployment of mirroring in cluster-based parallel virtual file systems to provide fault tolerance and analyzes the tradeoffs between the performance and the reliability in the mirroring scheme. It presents the design and implementation of CEFT,...
متن کاملImproved Read Performance in a Cost-Effective, Fault-Tolerant Parallel Virtual File System (CEFT-PVFS)
Due to the ever-widening performance gap between processors and disks, I/O operations tend to become the major performance bottleneck of data-intensive applications on modern clusters. If all the existing disks on the nodes of a cluster are connected together to establish high performance parallel storage systems, the cluster’s overall performance can be boosted at no additional cost. CEFT-PVFS...
متن کاملScheduling for Improved Write Performance in a Cost-Effective, Fault- Tolerant Parallel Virtual File System (CEFT-PVFS)
Without any additional hardware, CEFT-PVFS utilizes the existing disks on each cluster node to provide RAID-10 style parallel I/O service. In CEFT-PVFS, all servers are also computational nodes and can be heavily loaded by different applications running on the cluster, thus potentially degrading the I/O performance. To minimize the degradation, I/O requests can be scheduled on a less loaded ser...
متن کاملI/O Response Time in a Fault-Tolerant Parallel Virtual File System
A fault tolerant parallel virtual file system is designed and implemented to provide high I/O performance and high reliability. A queuing model is used to analyze in detail the average response time when multiple clients access the system. The results show that I/O response time is with a function of several operational parameters. It decreases with the increase in I/O buffer hit rate for read ...
متن کاملFault Tolerant File Models for MPI-IO Parallel File Systems
Abstract. Parallelism in file systems is obtained by using several independent server nodes supporting one or more secondary storage devices. This approach increases the performance and scalability of the system, but a fault in one single node can make the whole system fail. In order to avoid this problem, data must be stored using some kind of redundant technique, so that it can be recovered i...
