| Zusammenfassung: | The present invention is directed to a data storage system utilizing a number of data storage devices. Each of the data storage devices stores primary and mirrored copies of data. Furthermore, the data is arranged such that no one data storage device stores both the primary and mirrored copies of the same chunk of data. Data may be striped across the storage devices such that stripes containing primary copies of data chunks are interleaved with stripes containing mirrored copies of data chunks. |
