Frequently asked questions

What is the maximum bandwidth per InfiniBand port on this switch?

Each of the 34 QDR InfiniBand ports delivers 40 Gbps of bandwidth. The switch supports 4X QDR signaling rates with peak data rates of 40 Gbps per port in each direction, enabling ultra-high-speed inter-node communication for HPC clusters.

Can this switch be scaled to support larger clusters?

Yes. The Voltaire architecture supports up to 8 switches interconnected in a single fabric, enabling expansion from 34 ports to 272+ ports. This scalability allows organizations to grow compute clusters incrementally without replacing core switching infrastructure.

What cable types are supported by the InfiniBand ports?

The 34 QDR InfiniBand ports use QSFP connectors and support both 4X QDR copper cables and fiber optic cables. The 2 uplink ports are 10GbE SFP+ ports supporting both copper and optical transceivers for flexible deployment options.

How is this switch managed and monitored?

The switch includes an integrated management module enabling centralized configuration, monitoring, and troubleshooting. Management access is provided via the 2 integrated 10GbE ports, eliminating the need for separate out-of-band management infrastructure.

What are the environmental operating requirements?

The switch operates reliably between 50°F and 95°F (10-35°C) with relative humidity of 10-90% non-condensing. These specifications align with standard datacenter environmental controls, ensuring compatibility with typical climate-controlled facilities.

What is the total switch fabric capacity?

The switch provides 480 Gbps of total fabric capacity, supporting non-blocking, full-duplex communication across all 34 InfiniBand ports simultaneously. This ensures all ports can operate at full 40 Gbps capacity without bandwidth bottlenecks or performance degradation.

Is this switch suitable for machine learning and AI workloads?

Yes. The 40 Gbps per-port bandwidth and 480 Gbps fabric capacity make this switch ideal for distributed machine learning training requiring massive parallel data transfers between GPU/compute nodes with minimal latency.
