Summary
The blog post delves into the comprehensive process of building a SCION 25 Gbit/s Workstation, tailored for high-performance networking and testing. It starts with choosing the right components, focusing particularly on the LGA4677 socket fitted with a 12-core Intel Xeon CPU, and Mellanox NVIDIA BlueField-2 Dual-25G smart NICs. The author meticulously discusses each step, from planning and component selection to the assembly and configuration of the workstation. The project not only highlights technical specifications and challenges but also touches on the broader implications and potential of SCION technology in enhancing data plane performance critical for future networking demands.
Highlights:
- Detailed walkthrough of building a SCION 25 Gbit/s workstation including planning, component selection, and assembly.
- Insight into the SCION (Scalability, Control, and Isolation On Next-Generation Networks) technology and its potential to complement or replace BGP.
- Challenges faced and solutions implemented in achieving a low-noise yet high-performance workstation suitable for an office environment.
- Cost analysis and component sourcing strategy, revealing a total expenditure of approximately $4,700 USD.
- Performance testing and initial setup of the SCION workstation, achieving near line rate data transmission.
The construction of the SCION 25 Gbit/s Workstation was a detailed project involving careful planning and component selection tailored for high-performance networking. The workstation utilizes a 12-core Intel Xeon CPU compatible with LGA4677 socket, powering 64 PCIe Gen5 lanes to handle three Mellanox NVIDIA BlueField-2 smart NICs, each offering Dual-25G connectivity. This setup aims to significantly enhance the SCION Association's testbench capabilities for data plane performance testing and development, specifically targeting improvements needed for high-bandwidth applications like video calls over SCION OSS.
The total cost of the workstation reached approximately CHF 3,741.34 (around $4,700 USD), which included high-grade components such as Intel Ethernet 800 Series and NVIDIA/Mellanox ConnectX-5,6,7 smart NICs. The selection process emphasized not only performance but also the operational requirements like low noise levels for office compatibility, leading to the choice of specific server-grade mainboards and cooling systems. The workstation was assembled in a Phanteks Enthoo Pro II case, which supports extensive cooling and airflow management to maintain optimal operating temperatures for the high-performance hardware.
Upon completion, the workstation underwent rigorous testing, achieving 24.6 Gbit/s data transmission rates, demonstrating the effectiveness of the SCION infrastructure in handling high-speed data transfers. The setup process also included configuring the NICs for optimal communication within the Linux environment and ensuring all components were correctly installed and functional. This project not only serves as a robust testbed for ongoing SCION technology development but also provides a blueprint for building advanced networking workstations capable of handling next-generation data demands.
