42D0491 IBM Emulex 8Gb PCIe Single-Port HBA Adapter

The 42D0491 is an internal data connectivity interface module engineered to deliver cost-effective network transformation and enhanced system stability within multi-node server frameworks. Functioning as a high-reliability Fibre Channel host bus adapter unit and high-capacity system interconnect layer, this 8Gb single-port PCIe HBA assembly slides directly into enterprise chassis backplane bays using localized connection lines. Operating under system-regulated DC power parameters across multi-channel SAN storage controller architectures, it establishes high-efficiency routing pathways to manage internal data processing pipelines across high-density databases, continuous multi-threaded enterprise workloads, and legacy hardware consolidations. Its modular adapter layout and fault-isolated circuit architecture manage internal bus communication cleanly, shielding core operational paths from signaling latency, packet drops, or single-point-of-failure throughput disruptions during continuous high-availability enterprise runtime operations.
