Cloud storage systems are now mature enough to handle a massive volume of
heterogeneous and rapidly changing data, which is known as Big Data. However, failures …

A critical part of developing a reliable software system is testing its recovery code. This code
is traditionally difficult to test in the lab, and, in the field, it rarely gets to run; yet, when it does …

Cloud systems suffer from distributed concurrency bugs, which often lead to data loss and
service outage. This paper presents CloudRaid, a new automatical tool for finding …

Context Large-scale distributed systems are becoming commonplace with the large
popularity of peer-to-peer and cloud computing. The increasing importance of these systems …

Heterogeneity is the natural feature in distributed networks. Different from the traditional disk
array, the amount of data allocated on heterogenous peers may be not the same. To …

In this paper we present a technique for automatically assessing the amount of damage a
small number of participant nodes can inflict on the overall performance of a large …

Cloud service providers are consistently striving to provide efficient and reliable service, to
their client's Big Data storage need. Replication is a simple and flexible method to ensure …

This paper explores the coupling between power/thermal aspects of data center and the
vibrations caused by chassis/server fans in environments dominated by mechanical disks …
