TrueNAS Configurator
Pick a model and configure disks, RAID, networking and expansion. Capacity and code update live.
How would you like to start?
If you already know which model fits, jump straight to the model picker. Otherwise describe your use case briefly — we will suggest matching models.

Availability (high availability / HA)
Storage type
Required usable capacity
Usable capacity after RAID/ZFS and 80 % pool fill — without compression. The required raw capacity is calculated automatically (factor ≈ 1.7× for RAID-Z2).
Network connectivity
Growth expected?
Use case
Fibre Channel required?
Suggestions

Platform
ZFS best practice: do not fill pools beyond 80 %. Higher values reduce the displayed effective capacity.
A second, capacity-matched system at another site as the replication target — a recommendation appears on the right.
Drives
Reduce the count/hot-spares or add an expansion shelf (section below).

- No critical findings — standard configuration.
Open items before order
- Backup and DR strategy (RPO/RTO, restore goal) — finalize before order.
- Site readiness (rack U, PDU, UPS, cooling) — confirm.
- Network topology (switches, transceivers, VLANs, MTU) — align.
- Support level and response times per SLA — confirm.
- Delivery window and commissioning date — coordinate.
