Need More Thunderbolt Ports from Your Mac Pro?

Is a maximum of 42 devices not enough for you?

Here is my solution for your Thunderbolt device problems

The first problem

You have fully populated all of the Thunderbolt ports and maxed out the supported number of daisy-chained devices. You have more devices and need them to be connected without disconnecting other devices. What do you do?

The second problem

You have six 27" 2560x1440 or 30" 2560x1600 monitors for gaming, but you need these to be connected to the Thunderbolt ports to maximise the performance of refresh rates for gaming. What do you do when you want more devices and fast refresh rates?

Solution One

Component List

Buy a Sonnet Thunderbolt PCIe expansion chassis.
Buy an ASUS ThunderboltEX II/Dual expansion card.
Fix ASUS ThunderboltEX II/Dual expansion card within the Sonnet Thunderbolt PCIe expansion chassis.
Connect the Sonnet Thunderbolt PCIe expansion chassis to the Mac Pro with a Thunderbolt cable.
Connect the Thunderbolt out port on the Sonnet Thunderbolt PCIe expansion chassis to another Thunderbolt device within the Thunderbolt daisy chain.

Configuration

The above configuration allows for a maximum of 6 * 7 * 12 * 3 = 1512 devices or 6 * 6 * 12 * 3 = 1296 devices and six monitors connected to the Thunderbolt through from each of the last ports from the Sonnet Enclosures

Solution Two

Component List

Buy a Sonnet Thunderbolt PCIe expansion chassis.
Buy three ASUS ThunderboltEX II/Dual expansion card for each Sonnet Thunderbolt PCIe expansion chassis.
Fix ASUS ThunderboltEX II/Dual expansion card within the Sonnet Thunderbolt PCIe expansion chassis.
Connect the Sonnet Thunderbolt PCIe expansion chassis to the Mac Pro with a Thunderbolt cable.
Connect the Thunderbolt out port on the Sonnet Thunderbolt PCIe expansion chassis to another Thunderbolt device within the Thunderbolt daisy chain.
Connect the remaining Thunderbolt connectors to six devices and then connect to the Display Port connector on the ASUS ThunderboltEX II/Dual expansion card within the Sonnet Thunderbolt PCIe expansion chassis.

Configuration

The above configuration allows for a maximum of 6 * 12 * 3 = 216 devices and six monitors connected directly to the Sonnet Thunderbolt PCIe expansion chassis Thunderbolt through.
