505958-B21 HP BLC Qlogic Infiniband 32-Port 4x QDR Network Switch

HP BLC Qlogic 505958-B21

Power your cluster with the HP 505958-B21, an InfiniBand switch built for high-performance computing clusters, AI and machine-learning workloads and research computing.

It provides 32 ports for connecting compute nodes, storage servers and other switches. Support for QDR 40Gb/s InfiniBand data rates delivers very high bandwidth with low latency between nodes. InfiniBand fabrics use hardware offloads and low-latency switching to speed up MPI, parallel file systems and distributed applications. It is equally suited to building a new cluster or expanding an existing fabric. Non-blocking, low-latency switching helps parallel applications scale efficiently across many nodes. Use suitable copper or optical cables depending on rack-to-rack distances. A subnet manager is required to bring an InfiniBand fabric online. Depending on the model, it can run on a switch or a host.

Consistent switch models across a cluster simplify cabling plans, spares and fabric management. Simulation, analytics and AI training all benefit from low-latency interconnects. RDMA lets InfiniBand move data between servers with very little CPU overhead. Ordering by part number 505958-B21 helps you match the configuration, region and feature set exactly. Combine edge and spine switches to build fat-tree or other scalable topologies. For anyone sourcing InfiniBand connectivity, the 505958-B21 combines HP engineering with practical, everyday performance.
