Cloudflare's Gen 13 servers introduce AMD EPYC™ Turin 9965 processors and a transition to 100 GbE networking to meet growing traffic demands. In this technical deep dive, we explain the engineering rationale behind each major component selection.
Cloudflare’s Gen 13 servers double our compute throughput by rethinking the balance between cache and cores. Moving to high-core-count AMD EPYC ™ Turin CPUs, we traded large L3 cache for raw compute density. By running our new Rust-based FL2 stack, we completely mitigated the latency penalty to unlock twice the performance.
Cloudflare’s Gen 12 server is the most powerful and power efficient server that we have deployed to date. Through sensitivity analysis, we found that Cloudflare workloads continue to scale with higher core count and higher CPU frequency, as well as achieving a significant boost in performance with larger L3 cache per core.
Cloudflare is thrilled to announce the general deployment of our next generation of server — Gen 12 powered by AMD Genoa-X processors. This new generation of server focuses on delivering exceptional performance across all Cloudflare services, enhanced support for AI/ML workloads, significant strides in power efficiency, and improved security features.
Cloudflare Gen 12 Compute servers are moving to 2U1N form factor to optimize the thermal design to accommodate both high-power CPUs (>350W) and GPUs effectively while maintaining performance and reliability
The DC-SCM (Datacenter-ready Secure Control Module) decouples server management from the server motherboard. It provides flexibility to implement multiple server management and security solutions with the same server motherboard design
