405921-001 HPE 4Gb Dual Port Fibre Channel Mezz HBA

The 405921-001 is an internal mezzanine expansion module engineered to deliver cost-effective connectivity and enhanced system stability within multi-node server frameworks. Functioning as a dual-port 4Gb/s Fibre Channel host bus adapter (HBA), this high-speed network interface card integrates directly into blade server mezzanine expansion slots to provide dedicated, low-latency links to external storage area networks (SANs). Its fault-isolated layout manages high-throughput data streams cleanly, protecting critical processing paths from signaling disruptions, interface timeouts, and data drops during continuous high-availability runtime operations.
