HPE 634671-001

Voltaire 34-Port QDR InfiniBand + 2-Port 10 GbE LM Switch

The HPE Voltaire 634671-001 is a hybrid switch blending high-speed InfiniBand connectivity with dual 10 Gigabit Ethernet ports. Designed for demanding HPC and enterprise environments, it serves data centers that require ultra-low latency communication with broad protocol flexibility. Offering 34 QDR InfiniBand ports alongside two 10 GbE LM (Leaf Module) Ethernet connections, the unit enables seamless integration between compute clusters and high-bandwidth Ethernet storage or management networks. Perfect for organizations bridging InfiniBand-based servers or fabrics with Ethernet infrastructure, this switch ensures high throughput and streamlined networking operations. Refurbished units provide cost-effective upgrades for labs or deployments where budget meets performance.

Features

Organizations utilizing InfiniBand for high-performance computing benefit from its low-latency, high-throughput architecture. The 634671-001 integrates 34 ports of QDR (Quad Data Rate) InfiniBand—offering up to 40 Gb/s per port—with two versatile 10 GbE LM Ethernet connections. These Ethernet ports allow bridging to SANs, Ethernet storage devices, or management networks. In clustered environments, this switch enhances communication between nodes while enabling unified infrastructure management. Its dual-protocol capability makes it particularly valuable in mixed environments or for gradual transitions from InfiniBand to Ethernet.In IT environments leveraging virtualization, storage arrays, or backup networks over Ethernet, the 10 GbE ports ensure compatibility and high-speed data exchange. The switch’s compact form factor (Leaf Module style) and HPE branding promise integration with existing HPE networking frameworks. Refurbished models like the one typically available deliver excellent value for performance-hungry workloads. 

Advanced Options

Built for the rigors of HPC, research clusters, and data-intensive operations, the HPE Voltaire 634671-001 delivers robust performance with its 34 InfiniBand QDR ports—ensuring low-latency, non-blocking architecture suited for parallel compute traffic. HPE hardware-grade quality and use of proven Voltaire (now part of HPE ) InfiniBand tech underscore its reliability in mission-critical environments. The integrated 10 GbE ports offer flexibility for storage or management network connection, minimizing the need for separate interface devices. As Leaf Module form factor, deployment in server racks optimizes space utilization and simplifies integration with blade enclosures or modular systems.
