GC-WBAX210 Gigabyte 40G PCIe 3.0 x8 InfiniBand Network Card

High-Performance Mezzanine Interconnect Adapter delivering RDMA cluster I/O with the GC-WBAX210

The GC-WBAX210 is a dual-port QSFP+ mezzanine networking adapter designed to extend server platforms with low-latency, high-throughput fabric connectivity over a PCIe 3.0 x8 host interface. Positioned for HPC and data-intensive east-west traffic, the GC-WBAX210 enables consistent packet processing and deterministic transport where CPU cycles must remain available for compute and data services.

By combining Ethernet and InfiniBand fabric support with RDMA capability, the GC-WBAX210 aligns with clustered CPU nodes that require efficient memory-to-memory data movement across the network, reducing protocol overhead and improving job completion times for parallel workloads. The mezzanine form factor preserves PCIe expansion slots for storage or accelerators while maintaining predictable I/O pathways; dual QSFP+ ports provide up to 56Gb/s per port with support for 40G-class optics or DAC cabling for flexible top-of-rack integration. SR-IOV and protocol offloads allow the GC-WBAX210 to scale in virtualized compute stacks by presenting performant virtual functions per VM, while PXE boot support streamlines stateless provisioning and fleet rollout.

Why Choose the GC-WBAX210?

The GC-WBAX210 delivers a strong density-to-performance profile for nodes where bandwidth, latency, and isolation are operational requirements rather than optional enhancements. The GC-WBAX210 supports scalable fabrics with RDMA acceleration and SR-IOV segmentation, making it suitable for repeatable cluster deployments, predictable VM networking, and controlled expansion without redesigning the server I/O topology.

Gigabyte engineering focuses on platform compatibility and datacenter-grade integration, emphasizing stable signal integrity, validated interoperability, and lifecycle-aligned components to meet modern rack standards for serviceability and continuous operation.

Key Applications:

• HPC cluster interconnect and MPI fabrics
• RDMA-enabled east-west storage and data services
• High-throughput virtualization with SR-IOV
• Low-latency InfiniBand or Ethernet uplinks
