NX-802RU30
2U 8-Bay Rackmount Expansion Chassis
Engineered for high-density storage nodes, the NX-802RU30 provides uncompromised direct-attached storage expansion. Built on a rigid steel chassis with an unbottlenecked sas/sata backplane, it offers exceptional reliability for home labs, custom NAS builds, and enterprise archival systems.

Architecture & Capabilities
8-Bay Direct Attached
Supports eight 3.5" or 2.5" SATA/SAS drives in hot-swappable trays. The backplane uses a direct 1-to-1 routing path to external SFF connectors, preventing any expander-related bottlenecks for high-throughput ZFS arrays.
Thermals & Cooling
Equipped with three 80mm PWM hot-swap fan modules positioned immediately behind the drive wall. Creates massive static pressure to keep high-capacity helium drives operating perfectly under sustained loads.
Power & Expansion
Accepts standard 1U server power supplies (single or redundant options). Seamlessly daisy-chain multiple NX-802RU30 units to a single head node utilizing multi-port SAS HBAs.
Technical Specifications
Primary Use Cases
TrueNAS / ZFS Pools
The direct passthrough backplane makes this chassis the absolute best choice for TrueNAS SCALE/CORE deployments. ZFS requires direct access to disks without RAID controllers in the way, and the NX-802RU30 delivers exactly that.
Media/Video Archival
Video editing teams can pair the chassis with a multi-port HBA in their main workstation, expanding storage capacity by massive amounts without replacing their primary node.
Frequently Asked Questions
Technical clarification for system integrators and engineers.
Is the backplane SAS expander-based or direct passthrough?
The NX-802RU30 utilizes a direct passthrough backplane architecture without a built-in SAS expander. This ensures maximum unadulterated bandwidth to each drive, making it ideal for software-defined storage systems like TrueNAS and Unraid where direct disk access is mandatory.
What HBA cards are recommended for the head node?
We recommend standard LSI-based SAS HBAs flashed to IT mode (e.g., LSI 9207-8e, 9300-8e) depending on your required interface speed. Ensure the card matches the external SFF connectors you plan to utilize to link the head node to the DAS enclosure.
Does it support standard ATX power supplies?
No, the compact 2U form factor requires 1U server power supplies (redundant or standard). We provide validated active PFC power supply options at configuration time to ensure stability under heavy 8-drive spin-up loads.
