Capacity bounds for distributed storage
The information capacity of a distributed storage system is the amount of source data that can be reliably stored for long durations. Storage nodes fail over time and are replaced, and thus data is erased at an erasure rate. To maintain recoverability of source data, a repairer generates redundant data from data read from nodes, and writes redundant data to nodes, where the repair rate is the r...
متن کاملA Class of MSR Codes for Clustered Distributed Storage
Clustered distributed storage models real data centers where intraand cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR) codes achieving capacity of clustered distributed storage are designed. Focus is given on two cases: = 0 and = 1/(n−k), where is the ratio of the available crossand intra-cluster repair bandwidths, n is the total numb...
متن کاملExplicit Construction of MBR Codes for Clustered Distributed Storage
Capacity of the distributed storage system (DSS) is often discussed in the context of tradeoff between storage overhead and repair bandwidth. This paper considers capacityachieving coding for the clustered form of distributed storage that reflects practical storage networks. The suggested coding scheme is shown to exactly regenerate the arbitrary failed node with minimum required bandwidth, i.e...
متن کاملClustered Storage
The paper introduces the reader to a new paradigm shift that is currently taking place in the data storage industry: the movement toward Clustered Storage architectures. Clustered Storage architectures are changing the rules of how data is stored and accessed. This paper discusses the trends that clearly define clustered storage architectures as the future of data storage, detail the requiremen...
متن کاملPlacement of storage capacity in distributed video servers
In this paper, we study how to distribute storage capacity along a hierarchical system with cache–servers located at each node. This system is intended to deliver stored video streams in a video–on–demand way, ensuring that, once started, a transmission will be completed without any delay or loss of quality. We perform a detailed analysis of the start–up time delay for some storage distribution...
