Description
The HP 619985-001, featuring Voltaire technology, is a high-performance 36-port InfiniBand switch designed for demanding High-Performance Computing (HPC) environments. It supports 4x QDR (Quad Data Rate) InfiniBand connections, providing a raw data rate of approximately 40 Gigabits per second per port. This level of performance is critical for applications that require massive data throughput and extremely low latency, such as large-scale simulations, financial modeling, and scientific research clusters. The switch incorporates a reversed airflow design. This is a specific thermal management consideration often found in HPC environments where servers and switches are densely packed. Reversed airflow typically means the fan exhaust is directed towards the front of the rack, which can be beneficial depending on the overall data center cooling strategy and rack layout, ensuring components remain within optimal operating temperatures. With 36 ports, this switch offers significant connectivity for building large and complex InfiniBand fabric topologies. It enables high-speed, direct communication between compute nodes, storage systems, and other InfiniBand-enabled devices, minimizing bottlenecks and maximizing application performance. The combination of high bandwidth, low latency, and a substantial port count makes the HP 619985-001 a powerful component for advanced computing infrastructures.
