In order to meet the new requirements of multimedia applications, high-performance storage devices are needed with a very high cost per storage unit. However, if the access ow has particular requirements it is possible to adopt speci c data storage and management algorithms which can optimize the performance of traditional systems, thus allowing them to be used in multimedia servers. The paper ...

Identifying some pointers as invisible threads, for the purposes of storage management, is a generalization from several widely used programming conventions, like threaded trees. The necessary invariant is that nodes that are accessible (without threads) emit threads only to other accessible nodes. Dynamic tagging or static typing of threads ameliorates storage recycling both in functional and ...

The management of storage — allocation and garbage collection — is intended to be transparent to the programmer and user, placing the burden on the implementation. In most situations, the Icon programmer does not need to think about the allocation of storage or its consequences on program performance. Nonetheless, in cases where the amount of memory is limited or where programs require unusuall...

We describe the design of Mariposa, an experimental distributed data management system that provides high performance in an environment of high data mobility and heterogeneous host capabilities. The Mariposa design unifies the approaches taken by distributed file systems and distributed databases. In addition, Mariposa provides a general, flexible platform for the development of new algorithms ...

XML documents management is becoming an area of great research value and interest, since XML has become a popular standard for data communication and knowledge exchange over the Internet. Therefore, new issues have emerged in terms of storage and access control policies for XML documents. Concerning the storage issues, the majority of proposals rely on the usage of typical database management s...

Modern enterprise, web, and multimedia applications are generating unstructured content at unforeseen volumes in the form of documents, texts, and media files. Such content is generally associated with relational data such as user names, location tags, and timestamps. Storage of unstructured content in a relational database would guarantee the same robustness, transactional consistency, data in...

Nimble Storage was founded in 2008 on the core belief that the storage industry would experience a major transformation over the next decade, driven by two fundamental catalysts: First, that flash technology would require a ground-up storage system redesign, rendering incumbent disk-centric storage architectures inefficient and ineffective. Second, that cloud-based management with granular real...

The Panasas file system uses parallel and redundant access to object storage devices (OSDs), per-file RAID, distributed metadata management, consistent client caching, file locking services, and internal cluster management to provide a scalable, fault tolerant, high performance distributed file system. The clustered design of the storage system and the use of clientdriven RAID provide scalable ...

The proposed paper presents the DC/AC microgrid modeling using the Energy storage units and photovoltaic (PV) panels. The modal consists of a two stage power conversion. The power is supplied to the both DC and AC loads by this PV solar panels. The suitable way to explore the PV generation model is by using manufacturer datasheet. A bidirectional converter is connected to the battery storage sy...
