The Thunderbolt™2 NA381TB enclosure turns Mac mini into rackmount server, enabling power of Mac mini fully utilized by single Thunderbolt connection; it also transforms Mac mini into enterprise solution with over 100TB storage for data center, extra 3 PCIe slots for PCIe cards expansion, and is designed to fit for high-speed storage architecture. Any preferred RAID controller card can be selected to go into the NA381TB to make RAID available to storage. Professional PCIe cards such as video card, FC or 10GbE network card (sold separately) can even be added to NA381TB to work with Mac mini.

Simply, Mac mini becomes Enterprise Server
The Thunderbolt™2 NA381TB is equipped with two Thunderbolt™2 ports capable of daisy-chain up to 6 Thunderbolt™ devices and display, supporting I/O performance 20Gbps bi-directional. Once Mac mini with Thunderbolt 2 is released, the NA381TB can perform as fast as the Thunderbolt 2 throughput of the data rates 20Gbps. Built with rear easily removable host plate, the Mac mini can be integrated to NA381TB conveniently with existing Mac I/O accessible to users.

Excellent Cooling Design with Most Efficient Use of Space

The NA381TB rackmount enclosure is designed to have high efficiency airflow ventilation; even under the most mission-critical working environment, the Mac mini and each PCIe card are ensured to be staying at the coolest condition for running application smoothly. The Thunderbolt™ NA381TB also makes the most utilization of space for server; with the space-saving architecture, the Mac mini is transformed into enterprise server with PCIe expansion and mass storage upon no single space wasted.
