Flexible Architecture of Disk Array

Hai JIN, Jiangling ZRANG
1997 Journal of the Magnetics Society of Japan  
Redundant Array of Independent Disks (RAID) IS the most etlicient way to avoid the bottleneck problem between I/O subsystem's performance and the CPU processing power.  ...  Two kinds of special structures, RAID_table and RAID_map are proposed in order to implement FlexArch.  ...  Each byte in the map illustrates the usage of the corresponding block in the disk array.  ...

The mechanisms can effectively aggregate the bandwidth from a large number of distributed disks and statistically tolerate pear-disk performance variation.  ...  For example, for a 1GB data access using 64 disks, RobuSTore achieves average bandwidth of 186MBps for write and 400MBps for read, nearly 6x and 15x that achieved by a RAID-0 system.  ...  Acknowledgements Supported in part by the National Science Foundation under awards NSF EIA-99-75020 Grads and NSF Cooperative Agreement ANI-0225642 (OptIPuter), NSF CCR-0331645 (VGrADS), NSF NGS-0305390  ...

2018 2018 48th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN)  
We evaluate how several redundancy schemes perform in unreliable environments and show that alpha entanglement codes are flexible and practical codes.  ...  Data centres that use consumer-grade disks drives and distributed peer-to-peer systems are unreliable environments to archive data without enough redundancy.  ...  V.E.G. thanks Jay Lofstead, Ahmed Amer, Kragen Sitaker, and Hugues Mercier for stimulating discussions, and to Luiz Barroso for answering questions regarding availability in global systems.  ...
