On adaptive distributed storage systems
2015 IEEE International Symposium on Information Theory (ISIT), 2015In a distributed storage system (DSS), high data reliability is obtained by dispersing the data over a number of nodes over a network. In an (n, k) erasure code based DSS, a data file is first divided into k packets and then these k packets are encoded into n packets using an MDS code, and finally these n packets are distributed over n nodes so that ...

Information dependability in distributed systems: The dependable distributed storage system
Integrated Computer-Aided Engineering, 2014In distributed infrastructures data are usually scattered among different nodes and thus accessible by several users. It is therefore necessary to provide mechanisms and tools for managing the information, ensuring the access exclusively to authorized users avoiding malicious ones. Furthermore, satisfactory performance and adequate fault tolerance have

Storage-Repair Tradeoff for Hierarchical Distributed Storage Systems
2019 IEEE SmartWorld, Ubiquitous Intelligence & Computing, Advanced & Trusted Computing, Scalable Computing & Communications, Cloud & Big Data Computing, Internet of People and Smart City Innovation (SmartWorld/SCALCOM/UIC/ATC/CBDCom/IOP/SCI), 2019Real-world distributed storage systems (DSS) such as modern data centers are hierarchical in nature, in which storage nodes are organized in different racks and connected by a network. In such a hierarchical DSS, we focus on establishing the fundamental tradeoff between storage capacity and repair bandwidth.

BASIC Codes for Distributed Storage Systems
2017 26th International Conference on Computer Communication and Networks (ICCCN), 2017Distributed storage systems are composed by many unreliable storage nodes over a network. A data file is redundantly stored in multiple storage nodes to provide high reliability. Recently erasure codes with Maximum Distance Separable (MDS) property are gradually employed in distributed storage systems to reduce the cost of reliably storing large ...

Towards green distributed storage systems
2015 49th Asilomar Conference on Signals, Systems and Computers, 2015We model a distributed storage system consisting of energy harvesting nodes which store multiple files. To investigate the performance of file retrieval and node repair, we formulate two optimization problems: maximizing the number of retrieved (repaired) files given a deadline, and minimizing the retrieval (repair) time of a number of stored files. We

Coding Schemes for Distributed Storage Systems
2017This thesis is devoted to problems in error-correcting codes motivated by data integrity problems arising in large-scale distributed storage systems. We study properties and constructions of Maximum Distance Separable (MDS) codes, which are widely used in storage applications since they provide the maximum failure tolerance for a given amount of ...
