The end-to-end refresh of our server hardware fleet

This post announces an end-to-end refresh of Meta's server hardware fleet, introducing four new designs: Bryce Canyon (storage chassis), Big Basin (GPU server for AI training), Tioga Pass (compute server), and Yosemite v2 (multi-node compute platform). These designs leverage the Open Compute Project standards and incorporate improvements in density, performance, thermal efficiency, and serviceability. Key innovations include higher HDD density in Bryce Canyon, increased training throughput and memory in Big Basin, enhanced PCIe bandwidth and networking in Tioga Pass, and hot-swappable server cards in Yosemite v2. The designs also integrate OpenBMC for system management and are compatible with Open Rack v2.
