What are the port specifications of the HP Voltaire 4036?

It features 36 InfiniBand QDR ports in 4x configuration, each supporting 40Gb/s speeds with auto-negotiation to 20Gb/s or 10Gb/s. QSFP connectors enable flexible cabling with signal optimization, providing 9 virtual lanes and 4096-byte MTU for high-density HPC connectivity.

What performance does this switch deliver?

Delivers 2.88Tb/s non-blocking aggregate bandwidth and port-to-port latency under 100 nanoseconds. This fully non-blocking design eliminates I/O bottlenecks, ideal for high-performance clusters in scientific and enterprise applications.

What is the form factor and physical size?

1U rack-mounted switch, 19-inch width, 15-inch depth, weighing 8.50 lbs. Supports front-to-rear or reversed airflow with hot-swappable fans for dense rack deployments.

How is the switch managed?

Fully managed via CLI interface for monitoring operations, firmware upgrades, and port settings. Includes RJ45 10/100/1000 Ethernet, USB, and DB-9 console ports, plus system LEDs for status.

What power and cooling options are available?

Dual redundant hot-swappable power supplies (100-240VAC auto-sensing, max 216W typical 106W). Hot-swappable fan units with auto-heat sensing and reversed airflow option ensure high availability.

Is it suitable for large-scale HPC clusters?

Yes, with 36 ports scaling to thousands of nodes, 2.88Tb/s bandwidth, and <100ns latency. Designed for database, storage servers, and scientific computing in enterprise environments.
