There also is platform-agnostic system management for Yosemite and the four SoC server cards so they can be managed regardless of the vendor. The system will be compatible with Open Rack OCP standard, which can hold up to 192 SoC server cards in a single rack.

"With the design proposed as a contribution for OCP, we're excited to see what the rest of the community builds and deploys based on this submission," he wrote.

In addition, Facebook announced it is contributing the Wedge spec for top-of-rack network switches to the OCP, and is working with such tech vendors as Cumulus Networks, Big Switch Networks, Broadcom and Accton Technologies to develop a product package of the OCP community. Accton will begin shipping Wedge in the first half of the year, according to the company.

"The design of Wedge itself is distinctive from other top-of-rack switches in that we've embraced the idea of making the switch feel as much like a server as possible for ease of management and software development," Facebook software engineer Adam Simpkins wrote in a post on the company blog. "Further, Wedge is the basic building block for our new chassis switch (code-named '6-pack'), so once you're familiar with the Wedge specification, you'll be pretty close to understanding 6-pack, as it is simply a combination of Wedge boards networked together with Ethernet on the backplane."

Facebook announced the Wedge last year, and the 6-pack module in February.

The company also is making its FBOSS networking software—created for the Wedge—available to OCP members.

In addition, Facebook released OpenBMC, which opens baseboard management controller (BMC) technology and creates a framework for system management. Facebook will first leverage OpenBMC with Wedge, and then with 6-pack, according to company officials.
