Quick Overview

PCIe 2.0 expansion system/4U rackmount enclosure for new Mac Pro with Thunderbolt 2 ports. Integrated 300W power supply and auxiliary power connector for installed cards.



Manufacturer Part Number: XMAC-PS

Expand and Enclose Your New Mac Pro at the Same Time
The new Mac Pro has become the object of desire, but a lustrous finish hides its true beautythe massive power within. If you're a pro user in the video or audio industries, the Mac Pro offers the power you need, but lacks the built-in expandability you count on. In order to achieve this engineering feat, Apple designers stripped away components and space to a minimum, taking out PCIe slots and drive bays, and packed the remaining components into a small cylinder. Its compact size makes the new Mac Pro more transportable and rackable, but prevents onboard installation of PCIe expansion cards. In addition, the computer still requires an enclosure to make it road- or rack-ready and provide convenient cable management. Sonnet's xMac Pro Server PCIe expansion system/4U rackmount enclosure addresses these issues and increases a Mac Pro's potential in a big way.

Building on the concept of our award-winning xMac mini Server PCIe 2.0 expansion system/1U rackmount enclosure for Mac mini, we designed a 4U rackmount enclosure exclusively for the new Mac Pro, and integrated the three PCIe 2.0 slots, 20Gbps Thunderbolt 2 technology, and expandability of Echo Express III-R Thunderbolt 2 expansion chassis for PCIe cards. Like the III-R, xMac Pro Server provides space for you to mount additional equipment, such as storage expansion. To support a wide range of popular mobile racks, carts and portable rack cases, xMac Pro Server is just 16' deep. The xMac Pro Server securely holds the computer and installed cards, making your Mac Pro fully rack- and road-ready.

Connect Up to Three PCIe Cards to Your New Mac Pro
Sonnet's xMac Pro Server supports three full-length PCIe cards. It integrates a universal 300W power supply and includes a 75W PCIe power connector for cards that require supplementary power, such as the Avid Pro Tools|HDX or the new RED ROCKET-X. Even with all that power, xMac Pro Server is enviro-friendly; it automatically powers the PCIe expansion system on or off whenever the connected computer powers on or wakes, or powers off or sleeps, respectively.

Smart Design All Around
The xMac Pro Server has numerous thoughtful design touches. Its front panel mounted power switch turns the computer on and off without the need for you to reach around back. The front panel USB 3.0 port connects to the Mac Pro, enabling you to connect a keyboard, mouse, or thumb drive to the computer without having to access its ports from the back. Other Mac Pro interface ports are extended to the back of the chassis and mounted on the rear panel for convenient interfacing of the remaining connections: Gigabit Ethernet, HDMI, and USB 3.0 cables, as well as the power cord. Holes for cable ties enable you to secure cables inside, keeping them tidy while avoiding accidental disconnects. An included Thunderbolt cable connects your one of the Mac Pro's Thunderbolt 2 port to one of xMac Pro Server's Thunderbolt ports, linking the PCIe slots to the computer. Like the Mac Pro, xMac Pro Server's additional Thunderbolt port supports daisy chaining Thunderbolt peripherals such as additional PCIe expansion (like Sonnet's Echo Express III-R rackmount chassis), pro video breakout boxes, video capture and playback devices, audio I/O devices, and more. The xMac Pro Server includes adjustable and removable rackmount extension rails that allow the enclosure to be installed securely in a variety of racks from 16' to 26' deep.

Thunderbolt 20Gbps IconBuilt for Speed
The Mac Pro includes six high-bandwidth Thunderbolt 2 ports to compensate for its lack of internal expansion. The original 10Gbps Thunderbolt on older computers interface provided breakthrough bandwidth for external expansion, more than sufficient to support the maximum performance of most PCIe cards. However, some high-bandwidth cards such as the RED ROCKET, 16Gb Fibre Channel, multi-port 10 Gigabit Ethernet, and other bandwidth-hungry adapters require more than 10Gbps. Thunderbolt 2 technology removes this barrier by providing more bandwidth for demanding applications. The xMac Pro Server's 20Gbps Thunderbolt 2 interface takes full advantage of this increased bandwidth to ensure optimum performance from installed cards connected to the Mac Pro. If you need to connect a peripheral equipped with 10Gbps Thunderbolt, there's no problemxMac Pro Server is fully compatible with earlier generation Thunderbolt devices as well.

Steel IconSecurely Enclose Your New Mac Pro and PCIe Cards
Constructed of heavy-duty steel, xMac Pro Server's outer enclosure provides secure mounting and protection for the computer and PCIe cards installed inside. Hidden behind a handsome front panel, both the computer and PCIe card expansion system reside in separate modules to simplify setup and maintenance, allowing you to work with the computer or cards individually. We know that your Mac Pro is a beautiful, gleaming cylinder, so we constructed a protective cocoon for the computer out of steel, and covered it with soft touch padding to hold the Mac Pro firmly in place while protecting its mirror finish. There is leftover space in the enclosure, perfect for mounting additional equipment such as HDDs and SSDs, a tape drive, optical drive, or even a Qio MR pro media reader.

Cool, Quiet Operator
Fan AirflowThe new Mac Pro's cylindrical core is topped with a single large fan that quietly and efficiently cools the computer, drawing in cool air through the bottom and expelling warm air through the top. Mounted on its side inside xMac Pro server, the computer's airflow path remains unchanged and unobstructedfull, independent airflow through the computer is maintained according to Apple's specifications. The xMac Pro Server was designed to be remarkably quiet so that it can be comfortably used in noise-sensitive environments. The PCIe card expansion system is cooled separately with dual, ultra-quiet, temperature-controlled fans. Its fans vent warm air through custom Venturi openings with low form-drag grills, resulting in reduced air velocity, turbulence, and, consequently, fan noise. The fans are variable-speed, and the computer-modeled airflow management ensures that even hot-running cards and the chassis' components remain reliably cool without the need to install an extra PCIe blower card that would prevent the use of one of the three slots.

Every Thunderbolt-Compatible Card Supported
The xMac Pro Server supports three full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt-compatible card available. PCIe 1.1, PCIe 2.0, and PCIe 3.0 cards are supported.

RED ROCKET Supporter
If you're a RED ROCKET, or RED ROCKET-X user, you already know that the card normally takes up two PCIe slotsone for the card itself and another for the BNC connector bracket (for HD-SDI output). Sonnet designed xMac Pro Server to accommodate the card/bracket pair in a single slot. The xMac Pro Server includes mounting holes designed specifically for the installation of two BNC connectors, enabling you to install the RED ROCKET card in one slot and its BNC connectors in the Echo chassis' mounting holes, leaving the two remaining slots open. The extra bandwidth afforded by the Thunderbolt 2 interface significantly increases the ROCKET's throughput, too.

xMac Pro Server BNC Connector Ports
Designed for BNC Connector CablesxMac Pro Server's back panel has two mounting holes for BNC connectors, allowing the use of a RED ROCKET card without the need for the BNC connector bracket that would normally occupy a valuable PCIe slot.

PCIe Card Thunderbolt Compatibility Chart
Do you have a card in mind but aren't sure it's compatible with Thunderbolt? We've worked closely with PCIe card manufacturers to provide a list of compatible PCIe cards on our PCIe Card Thunderbolt Compatibility Chart. The chart provides an up-to-date list of cards that have been tested to be recognized over a Thunderbolt connection and compatible with Thunderbolt technology requirements.

Thunderbolt Cable LockThunderbolt Cable Lock Included
Sonnet includes a lock that secures the Thunderbolt cable connectors in place when plugged into xMac Pro Server. It is easy to install and prevents accidental cable disconnections.

5-Year Warranty Included at No Extra Cost
There's no need for you to pay an additional 1020% on top of the purchase price to extend the warranty period beyond one yearSonnet backs xMac Pro Server with its Pro 5-year warranty.

Expand More with Optional Mobile Rack Device Mounting Kits
Using Sonnet's optional Mobile Rack Device Mounting Kit, you can install two 5.25' mobile rack devices inside xMac Pro Server's enclosure and easily connect them to cards installed in the chassis. Connected to a 6Gb/s SAS host controller card, you could add an internal LTO 6 tape drive for backups plus an enclosure for four swappable 2.5' SSDs for fast storage. An alternate configuration might include a Sonnet Qio MR pro universal media reader (with its interface card installed in one of the chassis' PCIe slots) for quick ingests of files from SxS, P2, and CF memory cards. Or, install a 6Gb/s eSATA host controller in one of the chassis' slots and connect one full-height mobile rack enclosure for three swappable 3.5' hard disk drivesyou can migrate your old Mac Pro's drives to your new system. The Mobile Rack Device Mounting Kit includes an internal 100W power supply inside to power the installed devices, a large internal fan to cool the installed devices, and mounting hardware to secure the devices and the kit itself. To make your selections even simpler, Sonnet offers preconfigured kits that include the mobile rack devices, PCIe card, and necessary cables; you provide drives as necessary. No matter what you choose, Mobile Rack Device Mounting Kits enable you to add more expansion devices to your rack without taking up additional rack space.
