Question 10

What is true about DRE?

Answer 10

can span across physical enclosures in the appliances and have mixed drive sizes

Question 11

What is the spare rule for DRE?

Answer 11

each fault resiliency set reserves spare space equal to 1 physical drive (1 of 25)

full stripe writes occur regardless of 4+1 or 8+1

rebuild performance favors 8+1 (why it’s recommended to start at 10 drive minimum instead of 6)
