HP 487505-001 InfiniBand 4X DDR Dual Port PCIe Host Channel Adapter

HP 487505-001 InfiniBand 4X DDR Adapter

The HP 487505-001 is a dual-port PCIe host channel adapter built for InfiniBand 4X DDR clusters. It targets administrators who need low-latency, high-throughput interconnects between compute nodes or storage arrays. Each port supports the 4X DDR signalling rate over standard PCI Express slots. The card ships new under part number 487505-001.

Sustained load behaviour

Under continuous traffic the adapter maintains the 4X DDR link rate across both ports without dropping to a lower speed. The dual-port design balances streams so that neither port becomes a bottleneck during long-running MPI jobs or parallel file-system access. Heat output remains proportional to the 5.1 unit weight rating given by the manufacturer. Buyers who require single-port or higher-speed EDR links should look elsewhere.
