Storage sizing calculator

Plan Your Perfect Storage

Welcome to the Storage Sizing Calculator, the essential tool for every system administrator or DevOps engineer.

Stop guessing! Don’t base your hardware purchases on luck. Our calculator lets you transform your specific business needs (annual growth, lifespan) into a Net Capacity requirement and instantly provides you with the exact hardware recommendations.

How does the storage sizing calculator work?

Capacity planning is more than just a sum of sums. It requires taking into account:

1. Future Growth: How much data will you generate over the next 3, 5, or 7 years?
2. RAID Tolerance: The RAID level (such as RAID 6 or RAIDZ2) that you choose imposes a capacity penalty (Parity).
3. Safety Margin: The free space required for the proper functioning of file systems (such as ZFS) and future upgrades.

Key Recommendations

After you enter your objectives, this tool analyzes the efficiency of each popular RAID level and recommends the most cost-effective configuration, showing you:

• The minimum number of disks required.
• The usable capacity you will obtain.
• The efficiency of the chosen solution (percentage of wasted capacity in parity).

Whether you are planning a storage array for virtual machines, a cold data archive or an IOPS-intensive production environment, our tool ensures accurate sizing, saving you time and avoiding costly overpurchasing of unnecessary terabytes (TB).
