Drive Size

Choose NVMe drives to force F-Series (all-flash performance). HDD drives are best for capacity workloads.

RAIDZ Level

RAIDZ2 is recommended for production — it can survive 2 simultaneous drive failures with minimal performance impact. RAIDZ1 maximises usable space. Mirror gives the best read performance.

UAE Data Residency

A UAE-hosted TrueNAS design can support data-residency controls. PDPL compliance also depends on access, purpose, retention, security, contracts, rights, and transfer governance.

Common Questions

About This Calculator

How accurate is this calculator?+
The calculator uses iXsystems recommended RAIDZ configurations (8-drive vdevs) and standard ZFS parity efficiency ratios. It is a reliable sizing guide — actual hardware specifications depend on workload I/O profile, network throughput requirements, and budget. A free infrastructure assessment refines the estimate.
What is the difference between RAIDZ1, RAIDZ2, and RAIDZ3?+
RAIDZ1 tolerates 1 drive failure (87.5% usable with 8-drive vdev). RAIDZ2 tolerates 2 simultaneous failures (75% usable) and is the recommended default for production. RAIDZ3 tolerates 3 failures (62.5% usable) for mission-critical data. Mirror vdevs offer the best read performance at 50% usable.
What is an iXsystems appliance?+
iXsystems is the company behind TrueNAS. Their certified hardware appliances (Mini, R, H, M, F-Series) are purpose-built, pre-configured, and supported with gold/platinum SLAs. Apisylux is an authorised iXsystems partner in the UAE — we procure, deploy, and support these systems.
Can TrueNAS replace our Windows file server?+
TrueNAS Community Edition supports SMB file sharing and Active Directory integration, so it can replace Windows file-server workloads when the storage, permissions, backup, support, and migration design fit the organisation. ZFS adds integrity checks and snapshots, but capacity, performance, and cost depend on the selected hardware and topology.
Do you supply the hardware or just the software?+
Both. We can procure iXsystems certified appliances or custom-build systems using Supermicro/Dell hardware optimised for TrueNAS. All hardware is UAE-stocked with fast delivery. We install, configure, and provide ongoing managed support.
What happens after I use this calculator?+
