Consider a user who wishes to store file in multiple servers such that at least $t$ are needed reconstruct the file, and notation="LaTeX">$z$ colluding cannot learn any information about file. Unlike traditional secret-sharing models,...

This article systematically studies 99 distributed performance bugs from five widely deployed storage and computing systems (Cassandra, HBase, HDFS, Hadoop MapReduce ZooKeeper). We present the TaxPerf database, which collectively organizes analysis results as over 400 classification labels 2,500 lines of bug re-description. is classified into six categories (and 18 subcategories) by their root ...

The possibility to migrate a virtual server from one physical computer in a cloud to another physical computer in the same cloud is important in order to obtain a balanced load. In order to facilitate live migration of virtual servers, one needs to provide large shared storage systems that are accessible for all the physical servers that are used in the cloud. Distributed storage systems offer ...

This paper introduces Multiagent Systems (MAS) storage resource allocation algorithms and methods on a Peer-to-Peer (P2P) system of computer storage resources. MAS Complex Adaptive Systems (CAS) based on squirrels behaviors are proposed and evaluated to produce emergent global behaviors that can solve the storage resource allocation problem in a distributed system of peers. Experimental results...

With the deployment of larger and larger distributed storage systems, data reliability becomes more and more of a concern. In particular, redundancy techniques that may have been appropriate in small-scale storage systems and disk arrays may not be sufficient when applied to larger scale systems. We propose a new mechanism called delayed parity generation with active data replication (DPGADR) t...
