The full-stripe write technology supported by Dorado can effectively improve SSDs’ service life.
- A . True
- B . False
A
Explanation:
Based on characteristics of SSDs, OceanStor Dorado V6 uses ROW. In comparison with overwrite, full-stripe write avoids the overhead of reading disks brought by the write penalty, and also avoids frequent overwrites of parity data. After the data in the logical space is overwritten, the original data on the disk becomes garbage. The garbage data is released after being reclaimed in the background. Meanwhile, garbage reclaiming also produces extra overhead which has impact on the service performance after the reclaiming starts.
