The new Fort Worth data center will feature the latest Open Compute Project hardware designs — including Yosemite, Wedge, and 6-pack — making it one of the most advanced data centers in the world.
The new data center will be cooled using outdoor air instead of energy-intensive air conditioners, even during the hot summers in Texas.
Capital investment is projected to exceed $500 million within 5 years, including building construction costs and data center equipment.

In an engineering blog posting, Facebook said the 6-pack switch uses Wedge as its basic building block: it is a full mesh non-blocking two-stage switch that includes 12 independent switching elements. Each independent element can switch 1.28Tbps.
Facebook is currently building two configurations: One configuration exposes 16x40GE ports to the front and 640G (16x40GE) to the back, and the other is used for aggregation and exposes all 1.28T to the back. Each element runs its own operating system on the local server and is completely independent, from the switching aspects to the low-level board control and cooling system. Facebook said the advantage of this unique dual backplane design is the ability to modify any part of the system with no system-level impact, software or hardware.
