HP QLogic 4X QDR InfiniBand Switch Module

The HP 505958-B21 is a QLogic 4X QDR InfiniBand switch module that brings high-speed fabric connectivity to the HP c-Class BladeSystem. By delivering up to 40 Gbps on every port, it equips clustered servers and storage nodes with the bandwidth they need for data-intensive workloads, while keeping latency to a minimum.

Inside a BladeSystem enclosure, the module creates a dedicated InfiniBand network that bypasses the overhead of traditional Ethernet. Applications that rely on rapid message passing or large data exchanges—think scientific simulations, real-time analytics, or financial modeling—benefit from the consistent throughput and responsive performance the switch provides.

Installation is straightforward. The module slides into an interconnect bay and weighs only 4.4 pounds, so it adds virtually no strain on the chassis. Because the switching intelligence sits inside the enclosure, you reduce the need for additional external switches and cabling, which simplifies rack layouts and lowers power and cooling demands.

Administrators running high-performance computing clusters, virtualization farms, or scalable databases can use the switch to aggregate multiple blade enclosures into a single low-latency fabric. As requirements grow, adding more modules lets the network expand without disrupting existing workloads.
