質問 26
A storage system is configured with erasure coding, divided up into 12 data segments and 4 coding segments.
Each segment is written to different drives. What is the maximum number of drive failures that can be withstood without losing the data in this configuration?
- A. 0
- B. 1
- C. 2
- D. 3
正解: B
解説:
Explanation
In a typical erasure coded storage system, a set of n disks is divided into m disks to hold data and k disks to hold coding information, where n, m, and k are integers. The coding information is calculated from the data. If up to k of the n disks fail, their contents can be recomputed from the surviving disks.
