Pergamum: Replacing Tape with Energy Efficient, Reliable, Disk-Based Archival Storage
Figure 3: Inter-Tome Redundancy Pergamum can survive the loss of an entire tome through the use of inter-tome redundancy encoding. Segments on a single disk are grouped into regions , and a redundancy group is built from regions of identical sizes on multiple disks. To ensure data survival, each redundancy group includes extra regions on additional disks that contain erasure correction informat...
متن کاملUsing Storage Class Memory for Archives with DAWN, a Durable Array of Wimpy Nodes
The long life and low usage of archival data make cost considerations paramount. Today, most archival storage architectures depend on magnetic or optical media such as tape and disk because they have a low initial cost per byte. The high initial cost of storage class memories (SCMs) has been seen as prohibitive for archival use. Nevertheless, SCMs have many advantages for archival use, includin...

LoneStar: Design and Evaluation of an Energy-E cient, Disk-Based Archival Storage System by Matthias Grawinkel Tape has been the predominant storage target for digital archives, but with workloads becoming more active and storage media like hard disk drives catching up on costs-perbyte, the archival storage stack needs to be reinvestigated. Reliability, integrity, and durability are the main go...
متن کاملVirtual Tape Libraries: The Best of Tape and Disk Backup
Tape backup has traditionally been the mainstay of enterprise data protection when long-term data protection is required. As disk technologies have improved and economies of scale have driven down prices, disk adoption rates have surged and it would appear disk is poised to eclipse tape as the dominant backup platform and relegate tape to a minor archival and disaster recovery role. Numerous su...
متن کاملA Simple Mass Storage System for the SRB Data Grid
The functionality that is provided by Mass Storage Systems can be implemented using data grid technology. Data grids already provide many of the required features, including a logical name space and a storage repository abstraction. We demonstrate how management of tape resources can be integrated into data grids. The resulting infrastructure has the ability to manage archival storage of digita...
