Heading Off Correlated Failures through Independence-as-a-Service

Ennan Zhai, Ruichuan Chen, David Isaac Wolinsky, Bryan Ford
2014 USENIX Symposium on Operating Systems Design and Implementation  
Complementing existing post-failure forensics, we propose Independence-as-a-Service (or INDaaS), an architecture to audit the independence of redundant systems proactively, thus avoiding correlated failures  ...  may share deep, hidden dependencies, undermining redundancy efforts and introducing unanticipated correlated failures.  ...  While only a start, our proof-of-concept prototype and experiments suggest that INDaaS could be both practical and effective in detecting and heading off correlated failure risks before they occur.  ...

A Fresh Look at the Reliability of Long-term Digital Storage [article]

Mary Baker, Mehul Shah, David S. H. Rosenthal, Mema Roussopoulos, Petros Maniatis, TJ Giuli, Prashanth Bungale
2005 arXiv   pre-print
We present a simple model of long-term storage failures that helps us reason about the various strategies for addressing these threats in a cost-effective manner.  ...  Many emerging Web services, such as email, photo sharing, and web site archives, need to preserve large amounts of quickly-accessible data indefinitely into the future.  ...  Repairing from off-line media incurs the same high costs, long delays and potential correlated faults as auditing off-line media.  ...

JOSHUA: Symmetric Active/Active Replication for Highly Available HPC Job and Resource Management

K. Uhlemann, C. Engelmann, S. Scott
2006 2006 IEEE International Conference on Cluster Computing  
Most of today's HPC systems employ a single head node for control, which represents a single point of failure as it interrupts an entire HPC system upon failure.  ...  Test results as well as availability analysis of our proof-of-concept prototype implementation show that continuous availability can be provided by JOSHUA with an acceptable performance trade-off.  ...  This head node represents a single point of failure as it interrupts an entire HPC system upon failure.  ...
