TrueNAS operations tools
Use these tools to prepare an app deployment or compare workload assumptions. Start with the question you need to answer, then check the explanation beside the result before treating it as a system requirement.
TrueNAS RAM and ARC Calculator
Estimate a provisional RAM allowance from drive count, active apps and concurrent users. Compare the illustrative ARC budget and single-link network ceiling, with the formula shown beside the widget. Inputs stay in the browser. The result is a planning scenario to check against each application's documented requirements.
Put the estimate in context
Inventory applications before entering a count: a small utility and a database do not have interchangeable memory needs. The app migration guide helps organise deployment details. The custom service walkthrough covers the storage, device and network settings that a memory estimate cannot decide.
Looking for usable storage capacity?
Drive parity and capacity are a different calculation. Use the TrueNAS pool capacity calculator for a TrueNAS storage plan, or the ZFS RAIDZ calculator for the generic pool calculation. Read each tool's assumptions before comparing outputs.
