Ubiquiti UniFi UNAS Pro 8 2U Rack-Mount NAS
8 × 2.5/3.5-inch; drives not included2 × NVMe SSD cache2 × 10G SFP+; 1 × multigigabit RJ452U rack-mount
The Ubiquiti UniFi UNAS Pro 8 (UNAS-Pro-8) is an 8-bay, 2U rack-mount NAS for network file storage and sharing. It includes 16 GB memory, two hot-swappable 550 W power modules and UniFi Drive features, but no HDD or SSD media; drives must be selected separately.
Best For: A fit for organisations needing an 8-bay, 2U UniFi NAS with 10G networking, RAID 5/6/10 and shared-file features, and prepared to select and install drives separately.
Before you order: This is a diskless appliance: HDD/SSD media is not included, and the two M.2 NVMe slots are for cache. The rack is also separate; use the included slide rails and suitable support. SFP+ ports are 10G only. Suitable network equipment and cables, plus optional SFP+ optics or DAC cables, are selected separately. The stated 4 TiB NVMe limit has no specified per-slot or aggregate scope. RAID, snapshots and power redundancy do not replace independent backup or guarantee uninterrupted service; cloud backup requires the relevant provider account/service and network access.
What's in the Box
- Ubiquiti UniFi UNAS Pro 8 NAS chassis
- Two hot-swappable AC/DC 550 W power modules
- Rack-mount slide-rail hardware and fasteners
- One pictured mains cord; quantity beyond the pictured cord is not established
- Cable tie, small tool and pads
What It Means in Practice
- The 2U chassis measures 442.4 × 480 × 87.4 mm and weighs 11.5 kg; check rack clearance with connectors and cables.
- Included slide rails support four-post racks with 9.5 × 9.5 mm square holes and post depths of 600–1066 mm. Two-post setups need a suitable centre bracket or cantilever shelf; front ears alone are insufficient.
- Install appropriate drives before use: the eight 2.5/3.5-inch bays accept HDDs or SSDs, while the two M.2 NVMe slots are specified for SSD cache.
- For power redundancy, connect the two AC inputs to proper separate AC feeds. The 550 W rating is per module; system maximum consumption is 250 W and the drive power budget is 225 W.
What Will Not Work
- HDD/SSD media is not included; the M.2 slots are for cache, not specified as standalone user-storage bays.
- Both SFP+ interfaces are 10G only; 1G SFP support is not established.
- The rack is not included. Slide rails are required for safe support; front ears alone are insufficient. Two-post racks require a suitable centre bracket or cantilever shelf.
- The 4 TiB maximum NVMe SSD capacity is stated without specifying whether it applies per slot or in aggregate.
- Power redundancy requires appropriate separate AC feeds and does not guarantee zero downtime or data availability.
- RAID, snapshots and redundancy do not replace an independent backup. Cloud backup requires the relevant provider account/service and network access.
- For indoor operation only; no waterproof or weather-resistance claim is established.
