RAID Calculation Reference

RAID 0
Disks × Capacity (no parity, max performance)
RAID 1
Capacity ÷ 2 (mirroring, full copy)
RAID 5
(Disks - 1) × Capacity (single parity)
RAID 10
(Disks ÷ 2) × Capacity (mirror + stripe)

📖 Como Usar

  1. Enter daily data growth (e.g., logs, backups)
  2. Enter data retention period (days/months/years)
  3. Check redundancy if needed (DR setup)
  4. Select disk count and capacity
  5. Review usable capacity by RAID level
  6. Plan optimal configuration using recommended disk counts

✨ Recursos

  • ✓Daily/monthly/yearly data growth calculation
  • ✓Redundancy (DR) doubles required capacity
  • ✓RAID 0/1/5/10 capacity auto-calculation
  • ✓Requirement fulfillment visualization
  • ✓Minimum disk count recommendation per RAID
  • ✓Disk capacity presets (256GB to 20TB)

📐 Fórmula

RAID 5 Usable Capacity = (Number of Disks - 1) × Disk Capacity

💡 Explicação

  • •RAID combines multiple disks to optimize performance, reliability, and capacity.
  • •RAID 0: Striping provides maximum performance but no data recovery on failure.
  • •RAID 1: Mirroring creates a full copy. Only 50% capacity usable but highly reliable.
  • •RAID 5: One disk is used for parity, tolerating 1 disk failure. Most versatile option.
  • •RAID 10: RAID 1+0 combination offers both high performance and reliability, but uses 50% capacity.
  • •Redundancy (DR) stores duplicate data in a separate location for disaster recovery, requiring 2x capacity.

❓ Perguntas Frequentes

Q. Which RAID should I choose?

A. RAID 10 for databases and critical data, RAID 5 for file servers and backups. RAID 0 is suitable for temporary data or cache.

Q. What's the difference between RAID 5 and RAID 6?

A. RAID 5 tolerates 1 disk failure, RAID 6 tolerates 2. For large disks (4TB+), RAID 6 is recommended due to longer rebuild times.

Q. What is a hot spare?

A. A standby disk that automatically replaces a failed disk. Recommended for critical systems.

Q. Why is redundancy important?

A. To protect against disasters (fire, flood) or ransomware attacks by keeping duplicate data in a physically separate location.

Q. Why is actual capacity different from advertised?

A. Manufacturers use 1TB=1,000GB while operating systems use 1TB=1,024GB, resulting in about 7% difference.
