A performance study of the Babel file system

Abstract

collaborates with the research team at the DAIC in INFOTEC.Abstract-The performance of a distributed file system is defined by its hardware components, as well as its operational parameters. Even a slight change on a working condition may induce the major impact, for instance, on service response times. In this paper, we propose a set of experiments on the Babel file system using a client that sends requests for either file storage or retrieval, with two file sizes (512 MB and 1 GB). The aim is to achieve the best working conditions. To measure the performance of the Babel system we took the throughput and the response time when any of two operations (storage or retrieval) was running. The analysis of results showed that, for a given set of operational parameters, there is an optimal file size that gets the best out of the system's performance.keywords-redundancy, storage, Babel file system, availability.

A Federated Content Distribution System to Build Health Data Synchronization Services

“…• Reliability is added to mitigate problems caused by outages in the infrastructure where the data are processed and stored [13], [14]. This requirement is achieved by using the well-known IDA algorithm [15]. • Security (CIA: confidentiality, integrity, and access control) is added to solve problems that arise when the data is shared through non-controlled and untrusted environments, such as in the cloud [16], [17].…”

“…To provide the reliability property to the preparation/retrieval scheme, the information dispersal algorithm (IDA) [15] was used. In the preparation scheme, each file is segmented into n segments, which are called dispersal files, with redundancy.…”
