Drive Space Efficiency Using the Deduplication/Compression Function of the FUJITSU Storage ETERNUS DX S4/S3 series and ETERNUS AF series

Ceph-based FUJITSU Storage ETERNUS CD10000: an improvement over traditional RAID-based storage systems in OpenStack cloud environments

Using Similarity in Content and Access Patterns to Improve Space Efficiency and Performance in Storage Systems

In the past few years, we have seen a tremendous increase in digital data being generated. By 2011, storage vendors had shipped 905 PB of purpose-built backup appliances. By 2013, the number of objects stored in Amazon S3 had reached 2 trillion. Facebook had stored 20 PB of photos by 2010. All of these require an efficient storage solution. To improve space efficiency, compression and deduplica...

Techno-Economic Assessment of Heat Recovery in Series Condensers Arrangement: Hot and Humid Regions

A direct expansion (DX) HVAC system is an efficient way to supply fresh and dehumidified air to a built environment. To improve the efficiency of a conventional DX system in hot and humid regions, fresh air dehumidification and conditioning systems with energy recovery measures are the key equipment to reach such a goal. To achieve this goal an integrated system is proposed. The integrated syst...

Achieving Storage Efficiency through Emc Vnx File Deduplication and Compression

This white paper describes VNX File Deduplication and Compression, a feature of EMC VNX that increases the efficiency of storing network-attached storage (NAS) data. This paper outlines the motivation for increased storage efficiency, how VNX File Deduplication and Compression works, the principles and technical architecture behind it, and how it interacts with other VNX features and functions....

NUMERICAL APPROACH TO SOLVE SINGULAR INTEGRAL EQUATIONS USING BPFS AND TAYLOR SERIES EXPANSION

In this paper, we give a numerical approach for approximating the solution of second kind Volterra integral equation with Logarithmic kernel using Block Pulse Functions (BPFs) and Taylor series expansion. Also, error analysis shows efficiency and applicability of the presented method. Finally, some numerical examples with exact solution are given.
