What is the aggregate bandwidth of the HPE 632222-B21 switch?

The switch provides 34 QDR InfiniBand ports at 40 Gbps each, delivering 1.36 Tbps aggregate bandwidth. Combined with 2 10GbE ports, this enables massive data movement for HPC clusters and data centers. The architecture eliminates network bottlenecks in large-scale parallel computing environments.

Can this switch be integrated with existing Ethernet networks?

Yes. The two integrated 10 Gigabit Ethernet ports provide flexible uplink and management connectivity to IP networks. These ports support standard 10/100/1000Base-T technology, enabling seamless integration with existing enterprise Ethernet infrastructure without consuming InfiniBand fabric capacity.

How many switches can be connected in a single fabric?

Up to 8 HPE Voltaire switches can be connected in a single fabric, enabling incremental capacity expansion. This scalability allows organizations to grow their interconnect infrastructure from 34 ports to 272 InfiniBand ports while maintaining unified fabric management and consistent low-latency performance.

What management capabilities does this switch provide?

The integrated management module enables centralized monitoring, configuration, and troubleshooting of the switch fabric. Organizations gain visibility into port statistics, fabric health, and performance metrics. The managed architecture supports enterprise operational requirements for visibility and control across the interconnect infrastructure.

Is this switch suitable for scientific computing applications?

Yes. The QDR InfiniBand technology delivers deterministic, ultra-low latency performance essential for scientific simulations and computational research. The 40 Gbps per-port bandwidth eliminates network congestion, enabling rapid inter-node communication for parallel processing workloads typical in scientific computing environments.

What are the environmental operating specifications?

The switch operates reliably between 50°F and 95°F (10-35°C) with relative humidity from 10% to 90% non-condensing. These specifications align with standard data center cooling infrastructure, ensuring compatibility with typical enterprise environments without special environmental requirements.

What is the 'Low Memory Version' designation?

The low-memory architecture optimizes resource utilization and reduces total cost of ownership while maintaining full switching performance. This configuration is ideal for cost-conscious deployments where memory footprint is a consideration, without compromising the switch's core InfiniBand switching capabilities.
