Typical scenario

NAS capacity checked by adding disk labels

If a NAS specification requires available capacity but the supplier adds nominal disk capacities, the calculation may omit array configuration. Mirroring, redundancy and system partitions reduce data space. Units, file system and a dedicated spare in the actual delivery also matter.

What needs to be clarified

Check available capacity from installed disks and settings, distinguishing physical total, array space and user volume before comparing with a clearly defined requirement.

Materials to prepare

  • Requirement and specification defining the required capacity
  • Disk inventory and exported array and volume configuration
  • Management screenshots showing units, reserves and system version

What to compare

Match installed disk count, models and capacities to inventory. Check array level, spares and model limits. Convert to consistent units, showing redundancy, system partitions and file-system reservations separately. Compare the estimate with an empty volume’s available capacity without reconfiguring or deleting data for testing.

Possible outcome of the analysis

A technical calculation may trace capacity levels, tabulate actual settings and state whether the measured parameter meets an explicit requirement or its meaning needs clarification.

Limits of the conclusions

Total disk capacity is not user space. Capacity checking establishes neither performance nor fault tolerance; the report does not determine procurement legality, penalties or delivery acceptance.
