Zoned-RAID
Seon Ho Kim, Hong Zhu, Roger Zimmermann
Article No.: 1
DOI: 10.1145/1227835.1227836

The RAID (Redundant Array of Inexpensive Disks) system has been widely used in practical storage applications for better performance, cost effectiveness, and reliability. This study proposes a novel variant of RAID named Zoned-RAID (Z-RAID)....

Dynamic data reallocation in disk arrays
Ron Arnan, Eitan Bachmat, Tao Kai Lam, Ruben Michel
Article No.: 2
DOI: 10.1145/1227835.1227837

We present an application which optimizes the configuration of data in a disk array. The application relies on very little input data which is readily available from many storage devices. We validate the application in a controlled experiment and...

SLAS: An efficient approach to scaling round-robin striped volumes
Guangyan Zhang, Jiwu Shu, Wei Xue, Weimin Zheng
Article No.: 3
DOI: 10.1145/1227835.1227838

Round-robin striping, due to its uniform distribution and low-complexity computation, is widely used by applications which demand high bandwidth and massive storage. Because many systems are nonstoppable when their storage capacity and I/O...
