RAID calculator determines data protection level, usable capacity, and redundancy. Different RAID levels offer various tradeoffs between speed, capacity, and fault tolerance.
공식
RAID 0: Capacity = n×D; RAID 1: Capacity = D; RAID 5: Capacity = (n-1)×D; etc.
단계별 가이드
- 1Enter number of drives and drive capacity
- 2Select RAID level
- 3Calculate usable capacity and fault tolerance
풀어진 예시
입력
4 drives × 2TB each, RAID 5
결과
Usable: 6TB, Can lose 1 drive
RAID 5 parity stripe
피해야 할 일반적인 실수
- ✕Confusing hot spare with usable drives
- ✕Not accounting for RAID rebuild time vulnerability
