PACS Migration Time Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Transfer hours = archive TB * 8,388,608 megabits per TB / throughput Mbps / 3600 * overhead factor. Migration days = transfer hours / migration hours per day.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Archive Size: 250 TB
  • Sustained Throughput: 800 Mbps
  • Migration Window: 16 hr/day
  • Validation / Retry Overhead: 25%

Expected outputs

  • Estimated Migration Duration: 56.89 days
  • Adjusted Transfer Hours: 910.22 hours
  • Daily Transfer Capacity: 4.39 TB/day
  • Migration Time: 37d 22h 13m

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • Throughput is sustained across the migration window.
  • Overhead covers retries, validation, and operational pauses.
  • No archive contents are accessed.

Unit handling

  • Archive Size accepts values in TB.
  • Sustained Throughput accepts values in Mbps.
  • Migration Window accepts values in hr/day.
  • Validation / Retry Overhead accepts values in %.
  • Estimated Migration Duration is displayed in days.
  • Adjusted Transfer Hours is displayed in hours.
  • Daily Transfer Capacity is displayed in TB/day.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
