Eric,

The Xpander you have is operating at data transfer speeds of 80Gbps bi-directional. A Thunderbolt 2 port is only capable of operating at 20Gbps bi-directional. Neither Intel or Apple currently support discrete graphics cards residing in an external PCIe slot expansion chassis connected to the host via Thunderbolt.

Cubix had planned to release its own line of Xpanders using Intel Thunderbolt 2 technology during the late June timeframe. Due to a variety of factors, not the least of which is the current lack of Intel and Apple support for discrete GPUs hosted in an external slot expansion chassis or the 20Gbps data transfer speed limitation, Cubix has opted to focus its development efforts on its new PCIe Gen3 x16 (128Gbps data transfer rate) Xpander models plus its HostEngine dual Xeon-based workstations.

Hi Colin,

If you haven’t yet done so, you need to contact Mic Grover, Cubix Technical Support Manager (micg@cubix.com). There seems to be some issue which is neither Cubix or NVIDIA-related, but there are some things you can do to stabilize the system.

Hi Nodari – Please contact Cubix Customer Service if you have any unanswered questions at this point. They can assist you with configuration questions and help maximize the Xpander and NVIDIA GPU performance.

The difference in specs you’re referring to may be a difference in perspective – where you (more specifically, a component) are located relative to the PCIe bridges or switches. I’ll check on it and get back to you with any definitive response from my engineers.

You are correct sir! Forgive my brain-fart. We (Cubix) generally talk internally about PCIe bandwidth performance specs in Gbits per second, but you are absolutely correct in calling it 2.5GB/second, which also equals 20Gbps.

Thunderbolt 2 = 20Gbps bidirectional
PCIe Gen2 x4 = 20Gbps bidirectional
PCIe Gen3 x4 = 40Gbps bidirectional
PCIe Gen2 x8 = 40Gbps bidirectional
PCIe Gen3 x8 = 80Gbps bidirectional
PCIe Gen2 x16 = 80Gbps bidirectional
PCIe Gen3 x16 = 160Gps bidirectional

Therefore, the Thunderbolt 2 controller / interface should produce performance numbers similar to a PCIe Gen2 x4 interface.

Yes, 2-4 Titans per Xpander Desktop unit depending upon Xpander model. Also, since there’s less power draw then a GTX 690, no need for upgraded power supply (1200W runs about $300+ less expensive than the 1500W models)

Hi Eric,

From the Cubix end of things, you should be good to go with the 2009 Mac Pro. You will utilize Slot 2 (16-channel Gen 2) of the Mac Pro for the Xpander’s HIC, which connects to the Xpander unit of your choice (Xpander Desktop Series II, Desktop Elite, Rackmount Elite).

Hi Chris,

We would be interested to hear more about your comparison of GTX 690 vs GTX Titan, whenever you have time to contact us. We’re testing both cards ourselves, but we’re always interested in hearing more about the real-world experiences of customers such as yourself.
