The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...

Massively parallel storage systems are becoming more and more prevalent on HPC systems due to the emergence of a new generation of data-intensive applications. To achieve the level of I/O throughput and capacity that is demanded by data intensive applications, storage systems typically deploy a large number of storage devices (also known as LUNs or data stores). In doing so, parallel applicatio...

Energy production, distribution, and storage remain paramount to a variety of applications that reflect on our daily lives, from renewable energy systems, electric vehicles consumer electronics. Hydrogen is the sole element promising high energy, emission-free, sustainable metal hydrides in particular have been investigated as materials for this purpose. While offering highest gravimetric volum...

Existing data storage systems offer a wide range of functionalities to accommodate an equally diverse range of applications. However, new classes of applications have emerged, e.g., blockchain and collaborative analytics, featuring data versioning, fork semantics, tamper-evidence or any combination thereof. They present new opportunities for storage systems to efficiently support such applicati...

Multimedia applications such as Video On-Demand, Tele-Shopping, or Distance Learning require a storage facility for audio and video data, called video server. All these applications are very demanding in terms of storage capacity, storage bandwidth, and transmission bandwidth. A video server must also meet the requirements that stem from the continuous nature of audio and video. It must guarant...

The growing variety of data storage and retrieval needs is driving the design and development of an increasing number of distributed storage applications such as keyvalue stores, distributed file systems, object stores, and databases. We observe that, to a large extent, such applications would implement their own way of handling features of data replication, failover, consistency, cluster topol...

The File Design Analyzer is a software package which evaluates well-known data base storage structures and access methods in terms of secondary storage processing time and storage overhead required to service a set of user applications. It implements a first-order analytical model to specifically evaluate sequential, indexed sequential, direct access, and inverted multilist storage structures. ...

There are limits to the ability to migrate or deploy applications across geographically distributed/loosely coupled cloud resources, requiring substantial data movement and/or uniformly visible and accessible storage services across such distributed infrastructure. To address these issues, we propose and explore the utility of FleCS – an approach for providing FLExible Cloud Storage services in...
