4U, 24 bay Thunderbolt 2 Storage and PCIe Expansion

The Thunderbolt 2 NA381TB enclosure turns the Mac mini into an enterprise server with the capacity for nearly 100TB of storage. Designed to fit for high-speed SAN architecture, this chassis also features 3 PCIe slots for expansion. Preferred RAID controller cards can be installed to make the available storage RAID ready.












The Mac Mini Becomes an Enterprise Server

The NA381TB is equipped with two Thunderbolt 2 ports, each capable of daisy-chaining with up to 6 Thunderbolt™ devices including a display for extra quick 20Gbps bi-directional I/O performance. Built with an easily removable rear host plate, the Mac mini can be integrated to NA381TB conveniently with existing Mac I/O.

Optimized for Space and Cooling
The NA381TB’s design allows for optimal airflow ventilation to keep the Mac mini cool and applications running smoothly without compromising effective storage design.
