InfiniBand High-Speed Networking
InfiniBand HDR200 and NDR400 network design, installation and management. Low-latency, high-bandwidth interconnect for MPI workloads.
InfiniBand is a dedicated high-speed interconnect technology that delivers inter-node communication in HPC clusters at microsecond latencies and speeds of 200–400 Gb/s. Its RDMA support enables direct memory access without CPU involvement, providing a critical performance advantage for MPI workloads, deep learning training and large-scale simulations. Mevasis delivers end-to-end InfiniBand services, from fabric design and physical installation through driver configuration to production testing.
Beyond raw speed, InfiniBand fabrics include quality-of-service and adaptive routing that protect latency-sensitive traffic under heavy load. Correctly configured, they provide the RDMA path that lets MPI libraries, BeeGFS and AI frameworks exchange data with little CPU overhead.
Key Features
Microsecond Latency
RDMA technology enables direct inter-node memory access without CPU involvement, keeping application latency at the 1–2 µs level. This is essential for tightly coupled MPI codes where even microseconds matter. Communication overhead is dramatically reduced compared with standard TCP/IP.
Fat-Tree Fabric Architecture
A fat-tree topology guaranteeing full bisection bandwidth ensures performance does not degrade as the cluster grows. Adding more switches and links scales capacity linearly, so the fabric never becomes a bottleneck. This makes the architecture highly predictable for expansion planning.
End-to-End Installation and Testing
Design, physical installation, MLNX_OFED driver configuration and IMB/OSU benchmark tests are carried out systematically by our team. Each link and switch is validated against its rated performance before production. The entire fabric is documented so future maintenance is straightforward.
Continuous Monitoring and Support
A Prometheus + Grafana fabric monitoring system tracks port errors, temperature and traffic in real time. Proactive alerting catches degradation before it escalates into a major outage. Ongoing support keeps the fabric healthy and at peak performance.
Frequently Asked Questions
InfiniBand should be chosen for workloads that require intensive inter-node data exchange, such as MPI-based parallel computing, deep learning training and large-scale simulation. When the latency and bandwidth of standard Ethernet networks become insufficient for such workloads, InfiniBand HDR200 or NDR400 technology delivers a decisive performance advantage.
Mevasis provides end-to-end service from InfiniBand network design through installation to operational management. Fabric topology planning, switch configuration, RDMA-compatible driver installation, MPI performance tuning and production readiness testing are all carried out by our team. Post-installation monitoring and technical support services are also provided.
InfiniBand infrastructure cost varies by port count, speed tier (HDR200 or NDR400), switch architecture and cable type. We recommend filling in the request form to obtain an accurate project-specific quote; our team will evaluate your needs and present tailored pricing.
