Purchase readiness

Turn a NAS plan into a purchase checklist

A shopping cart should be the output of the plan. Use a checklist to make capacity, compatibility, power protection, and recovery requirements visible together.

Verify the primary system

Check usable-capacity target, drive bays, platform expansion rules, networking, memory limits, noise, power draw, and the exact compatibility list.

Verify each drive model

Record the exact model number, capacity, recording technology, warranty, workload specification, firmware notes, and a realistic replacement candidate.

Fund recovery before capacity upgrades

Reserve budget for a separate local or offsite target, retention, restore documentation, and the first representative restore test.

Keep four acquisition totals separate

Record the primary array, independent backup, UPS, and networking changes as four separate totals. This prevents a low enclosure quote from hiding the cost of the recovery path or the infrastructure needed to use it.

If a requirement is already covered, record that decision explicitly. For planned purchases, compare quotes in one currency and attach each quote to the same capacity, backup, shutdown, or network specification.

Add the operating horizon when it matters

Use measured whole-system watts and your energy tariff to add an operating-cost boundary across the same planning horizon as the capacity forecast. Keep the energy value separate from acquisition cost so changes in load, uptime, or tariff remain easy to update.
