TL;DR: In this paper, a storage system that performs remote copy between two or more storage apparatuses and a host computer using such storage system is improved, where a third storage apparatus including a third volume is coupled to a first storage apparatus, and a fourth storage apparatus with a fourth volume being coupled with a second storage apparatus.

TL;DR: In this paper, the first node is configured to create a redundant code using a combination of data blocks received from the two or more other nodes and store the created redundant code to a storage device different from storage devices holding the data blocks used to create the redundant code.

TL;DR: The NTIRE 2021 challenge on perceptual image quality assessment (IQA) as discussed by the authors was held in conjunction with the New Trends in Image Restoration and Enhancement workshop (NTIRE) workshop at CVPR 2021.

TL;DR: In this paper, a storage apparatus for which a hierarchical data management system is adopted is designed so that when receiving a read request for a first logical area to which a first storage area of a first disk device in a virtual volume is allocated, whether or not to migrate data in a first file area of the first storage device, to a storage space of a second storage device is decided according to an access frequency to the first file space in synchronization with the read request.

TL;DR: In this article, a row of stripes comprising multiple data elements obtained by segmenting a prescribed data unit, and a redundancy code for rebuilding the data elements, is distributively stored in multiple first storage apparatuses, which are more numerous than the total number of stripe data elements.
