RAID Configuration
?
RAID 6 extends RAID 5 with dual distributed parity, surviving two simultaneous drive failures. Excellent for larger arrays where rebuild time is critical. Lower write performance than RAID 5 but provides superior fault tolerance. Requires minimum 4 drives and provides capacity of N-2 drives.

🎯 VMS Storage Guidelines

  • Small sites (<10TiB): RAID 5 for cost efficiency
  • Medium sites (10-50TiB): RAID 6 for dual drive protection
  • Large sites (>50TiB): RAID 10 for performance + redundancy
  • Critical systems: Always use hot spares
  • Write-intensive: Avoid RAID 5/6, prefer RAID 10
  • Plan for 20% growth over 3 years

💾 Storage Technology

  • HDD: Cost-effective for large capacity needs
  • SSD: High performance, lower capacity per dollar
  • Enterprise drives for 24/7 operation
  • Match drive speeds within array
  • Consider warranty and MTBF ratings
  • NVMe for maximum performance requirements

📊 Capacity Planning

  • Plan for 150% of current requirements
  • Account for OS and application overhead
  • Reserve 10-15% for optimal performance
  • Consider backup storage requirements
  • Factor in compression ratios for video
  • Binary vs Decimal: 12TB = 10.91 TiB actual

⚡ Performance Characteristics

  • RAID 0: Maximum performance, no redundancy
  • RAID 1: Good read performance, 50% capacity
  • RAID 5: Balanced, poor write performance
  • RAID 6: Better protection than 5, slower writes
  • RAID 10: Best performance with redundancy
  • RAID 50/60: Better performance than 5/6

🛡️ Fault Tolerance Matrix

  • JBOD/RAID 0: No protection – avoid for critical data
  • RAID 1/10: Can lose multiple drives safely
  • RAID 5: Single drive failure tolerance
  • RAID 6: Dual drive failure tolerance
  • RAID 50: Multiple failures (different sub-arrays)
  • Hot spares reduce rebuild time significantly

🔧 Implementation Best Practices

  • Use dedicated RAID controllers for best performance
  • Enable write-back caching with UPS protection
  • Monitor drive health with SMART data
  • Test recovery procedures regularly
  • Document configuration for future reference
  • Maintain environmental monitoring
🚀 Galaxy-Class Recommendation: For mission-critical VMS applications, RAID 10 provides the optimal balance of performance, capacity, and fault tolerance. Use enterprise-grade drives with hot spares and plan capacity at 150% of current requirements for sustained performance and future growth.
Understanding Storage Calculations: Drive manufacturers advertise capacity in decimal TB (1TB = 1,000³ bytes), but operating systems report binary TB (1TB = 1,024³ bytes). The 9% “File System Use” represents this conversion difference plus actual filesystem overhead – what you’ll actually see available in your OS. Our calculator shows both raw theoretical capacity and actual usable capacity that matches real-world storage management systems.
