The concept of providing transparent access to a collection of files in a mass storage system is a familar one. The goal of this project was to investigate the feasibility of providing similar access to a collection of persistent, complex objects. We describe an architecture for interfacing a persistent store of complex objects to a hierarchical storage system. Persistent object stores support ...

Large-scale scientific experiments or simulation programs often generate large amounts of multidimensional data. Data volume may reach hundreds of terabytes (up to petabytes). In the present and the near future, the only practicable way for storing such large volumes of multidimensional data is tertiary storage systems. But commercial (multidimensional) database systems are optimized for perfor...

Storage consumption continues to grow rapidly, especially with the popularity of multimedia files. Storage hardware costs represent a small fraction of overall management costs, which include frequent maintenance and backups. Our key approach to reducing total storage management costs is to reduce actual storage consumption. We achieve this in two ways. First, we classify files into categories ...

Recently storage management has emerged as one of the main problems in building cost effective storage infrastructures. One of the issues that contribute to management complexity of storage systems is maintaining previous versions of data. Up till now such functionality has been implemented by high-level applications or at the filesystem level. However, many modern systems aim at higher scalabi...

in a large scale cyclic storage system ,as the number of rule parameters and/or number of operating period increase, general purpose gradient-based nlp solvers and/or genetic algorithms may loose their merits in finding optimally feasible solution to the problem. in these cases hybrid ga which decomposes the main problem into two manageable sub-problems with an iterative scheme between ga and l...

Cloud storage is one of the most popular services techniques in cloud computing environment. A crucial problem to be addressed in the cloud storage system concerns the security mechanism of protecting the private data and sharing data with other users. Cloud storage services are inherently insecure as the management technique of the data in the cloud storage is controlled by third parties beyon...

Deduplication in storage systems has gained momentum recently for its capability in reducing data footprint. However, deduplication introduces challenges to storage management as storage objects (e.g., files) are no longer independent from each other due to content sharing between these storage objects. In this paper, we present a graph-based framework to address the challenges of storage manag...
