Sonnet ( www.sonnettech.com) has announced the Mobile Rack Device Mounting Kit – Thunderbolt 2-to-PCIe Card Expansion Edition, the latest addition to their line of Thunderbolt 2-to-PCIe card expansion systems.

The new chassis is an accessory for Sonnet’s xMac Pro Server and Echo Express III-R rackmount expansion systems, and is itself a self-contained three-slot PCI Express (PCIe) expansion system that mounts inside the xMac Pro’s or III-R’s enclosure and can connect to a second 20Gbps Thunderbolt 2 bus on a Mac Pro computer.

The PCIe Card Expansion Edition enables the use of a variety of high-performance PCIe cards with the latest Mac Pro computer or any other computer with Thunderbolt or Thunderbolt 2 ports. The new model supposedly supports every low-profile, Thunderbolt-compatible PCIe card on the market. 

The Thunderbolt 2-to-PCIe Card Expansion Edition will be demonstrated at the 2015 NAB Show in booth SL10824. It’s due to be available this summer at a manufacturer’s suggested retail price of US$699.
