HP 727054-B21 Ethernet 10Gb 2-Port Adapter

The HP 727054-B21 delivers dual-port 10 Gigabit Ethernet connectivity over a PCIe 3.0 x8 interface — the standard specification for production server networking in enterprise and data center environments. At 10GbE per port, this adapter moves 10x the bandwidth of gigabit infrastructure, which translates directly to reduced backup windows, faster NFS and iSCSI storage throughput, and the ability to consolidate multiple 1GbE ports into a single high-bandwidth connection. The PCIe 3.0 x8 host interface provides approximately 64 Gbps of theoretical bandwidth — a bus that will not constrain either port under full simultaneous load. The SFP+ cage design is the professional choice for structured data center cabling: transceiver-based connectivity means you match the optical or copper medium to the run length and infrastructure rather than being locked into a single cable type.

This adapter is built for HPE ProLiant server environments — virtualization hosts, database servers, and NAS appliances where 1GbE has become the bottleneck and a single additional PCIe slot investment can meaningfully change I/O headroom. The dual-port design specifically enables the two most common 10GbE deployment patterns: NIC teaming for redundancy and aggregated bandwidth to a single upstream switch, or dual-segment connectivity where the server needs simultaneous presence on separate networks — storage and production, or management and data plane. The HPE OEM designation means iLO integration and ProLiant Driver Kit support work as expected in certified configurations. Administrators deploying this card in non-HPE environments should verify driver availability and expect to forgo HPE-specific management integration.
