Sumeet Sobti Intermemory.net The Evolving Field of Distributed Storage Memory is a fundamental commodity of computation. Storage systems provide memory that costs far less than RAM and has greater persistence, but suffers from much lower data transfer bandwidths and higher access latencies. These attributes — cost, persistence, bandwidth, and latency — are the traditional evaluation metrics for...

This paper presents a convergence of distributed Key-Value storage systems in clouds and supercomputers. It specifically presents ZHT, a zero-hop distributed key-value store system, which has been tuned for the requirements of high-end computing systems. ZHT aims to be a building block for future distributed systems, such as parallel and distributed file systems, distributed job management syst...

The rapid advances in the computer industry allow building larger systems that require mass storage volumes. As storage space increases, its management becomes increasingly difficult. In contemporary enterprise storage systems, performance has developed into a major bottleneck, which negatively affects the overall IT performance. Centralized solutions are often infeasible and thus a distributed...

In wireless distributed storage systems, storage nodes are connected by wireless channels, which are broadcast in nature. This paper exploits this unique feature to design an efficient repair mechanism, called broadcast repair, for wireless distributed storage systems in the presence of multiple-node failures. Due to the broadcast nature of wireless transmission, we advocate a new measure on re...

Digital information is a critical resource, creating a need for distributed storage systems that provide sufficient data availability and security in the face of failures and malicious attacks. However, the requirements for achieving high availability and security with distributed storage systems usually conflict with each other. This paper proposes a novel data dispersal/encryption scheme impr...

Regarding the advances in technology and anxieties around high and growing prices of fossil fuels, government incentives increase to produce cleaner and sustainable energy through distributed generations. This makes trends in the using microgrids which consist of electric demands and different distributed generations and energy storage systems. The optimum operation of microgrids with consideri...

In Distributed Storage Systems (DSSs), usually, data is stored using replicated packets on different chunk servers. Recently a new paradigm of Fractional Repetition (FR) codes have been introduced, in which, data is replicated in a smart way on distributed servers using a Maximum Distance Separable (MDS) code. In this work, for a non-uniform FR code, bounds on the FR code rate and DSS code rate...

Parallel applications running on clusters require both high-performance communications between nodes and efficient access to the storage system. We propose to improve the performance of distributed storage systems in clusters by efficiently using the underlying high-performance network to access remote storage systems. Storage and parallel computation have very different requirements. We show t...
