Specification of a distributed storage system
Computer Communications, 1996In many distributed telecommunications applications, the Quality of Service is largely determined by the performance and reliability of the distributed storage system. In this paper, we present the specification of a distributed database function which conforms to the Reference Model of Open Distributed processing (RM-ODP), the ISO/ITU-T standard.

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

Graftage Coding for Distributed Storage Systems
2018 IEEE Global Communications Conference (GLOBECOM), 2018Recently, several remarkable works [1]-[5] constructed regenerating codes to offer intermediate tradeoffs between storage and bandwidth. Unlike regenerating codes, this paper proposes to graft codes together to provide various such intermediate tradeoffs.

Flexible Consistency for Distributed Storage Systems
2017 IEEE International Conference on Smart Cloud (SmartCloud), 2017Consistency is a critical issue in distributed storage systems. Data in distributed storage systems are replicated across multiple storage nodes. When a copy of data is modified, all other copies need to be updated to prevent clients from reading stale data. However, such strong consistency requires the system to wait for all replicas to finish updates

Distributed storage allocation for heterogeneous systems
2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013We consider a distributed storage system where the storage nodes have heterogeneous access probabilities. The problem is to allocate a given storage budget across the nodes so as to store a unit-size data object with maximum reliability. We propose efficient algorithms for optimizing over several classes of allocations. In the basic one-level symmetric

Inventory control of storage in distribution systems
2012 American Control Conference (ACC), 2012Distribution-side energy storage is a natural mechanism for absorbing variability from renewable sources, and hence minimizing costly reliance on generator reserves. We consider a simple contract between a producer with uncertain output and storage. The optimal storage scheduling strategy is shown to be an inventory control-like policy, which we use to
