RAID 1 MIRROR MESHED INTO A CO-EXISTING RAID 5 PARITY STREAM |
| 摘要 |
A method includes storing an operating system in minor stripes on a first data storage device forming a first logical storage unit, and storing data in major stripes across a plurality of data storage devices forming a second logical data storage unit. Each major stripe includes a plurality of minor stripes storing data and a parity stripe. The method further includes calculating the parity stripe from the plurality of minor stripes within the major stripe and a corresponding one of the minor stripes on the first data storage device, wherein the minor stripes on the first data storage device match the size of the minor stripes on the array of data storage devices. |

1. A method, comprising:
storing an operating system in minor stripes on a first data storage device forming a first logical storage unit; storing data in major stripes across a plurality of data storage devices forming a second logical data storage unit, wherein each major stripe includes a plurality of minor stripes storing data and a parity stripe; and calculating the parity stripe from the plurality of minor stripes within the major stripe and a corresponding one of the minor stripes on the first data storage device, wherein the minor stripes on the first data storage device match the size of the minor stripes on the array of data storage devices. |
