Sonnet will have xMAC Pro Server from June. Based on the concept of the award-winning xMac mini Server PCIe 2.0 expansion system/1U rackmount enclosure for the Mac mini, a 4U rackmount enclosure was designed exclusively for the new Mac Pro and incorporated three PCIe 2.0 slots, 20Gbps Thunderbolt technology, and Echo Express expandability III – R Thunderbolt 2 expansion chassis for PCIe cards.
Like the III – R , the xMAC Pro Server provides space for you to fit additional equipment, such as storage expansion. To support a wide range of popular mobile racks, carts and portable rack cases, the XMAC Pro Server is only 16” deep. The xMAC Pro Server firmly holds the computer and installed cards.
