The Open Compute Project (OCP)-compliant Tundra server family is based on Cavium’s, 64-bit ARMv8 ThunderX workload optimized processors, enabling build-to-order server solutions for users with specialized hardware requirements in bioinformatics, federal government, enterprise, financial and Internet segments. The server platforms focus on highly-scalable Hyperscale and HPC-type workloads including big data, large-scale graph analytics, molecular dynamics, and Ceph / cloud storage. Performance is driven by ThunderX ARMv8 SOCs optimized for these workloads, with up to 48 high performance custom cores, very high memory bandwidth, and large memory capacity. Adding to these high-performance features are integrated accelerators for storage, networking or security, offloading from the main ARMv8 CPU cores and enabling best-in-class performance. In addition, integration of Ethernet fabric interfaces and storage controllers reduces both power and cost, driving reductions in TCO.
