Why 24TB of Storage Does NOT Mean 24TB Usable Capacity

George Fady Lv1Posted 2026-May-31 22:49

Many engineers are surprised when a datastore shows less capacity than the installed disks.

Example:

Raw Capacity = 24TB

Replica Policy = 2 Copies

Storage Efficiency = 85%

Calculation:

24 ÷ 2 × 85%

≈ 10.2TB Usable

Key Point

Always calculate usable storage based on replica settings instead of raw disk capacity.
