Avoiding disaster when your hard drive fails

We propose a new algorithm for recovering asynchronously from failures in a distributed computation. Our algorithm is based on two novel concepts-a fault-tolerant vector clock to maintain causality information in spite of failures, and a history ...

Failures or unexpected events are inevitable in critical and complex systems. Proactive failure detection is an approach that aims to detect such events in advance so that preventative or recovery measures can be planned, thus improving system ...

A hard disk drive (HDD) is a critical component in computers. The failure of HDD can result in the users' data loss and computer downtime. Both consequences cause inconveniences to the users. Therefore, detecting the impending failure of HDDs becomes a ...
