The HPE Ethernet 10Gb 2-port 521T Adapter (part number 867707-B21) connects to servers via PCIe 3.0 x4, delivering the bandwidth ceiling required for demanding enterprise workloads while ensuring broad host compatibility across modern infrastructure. Built around the Intel X550 network controller, this low-profile PCIe adapter provides two RJ-45 copper ports rated for 10 Gbps per port, with intelligent auto-negotiation across 100Mbps, 1GbE, 2.5GbE, 5GbE, and 10GbE speeds. The adapter supports Cat6a cabling at full 10GbE line rate up to 100 meters, while backward-compatible Cat5e is supported at 1GbE speeds. Advanced features include jumbo frames up to 9,600 bytes, TCP/UDP/IP checksum offload, LSO, LRO, and RSS for optimized throughput, plus SR-IOV virtualization support and IEEE 802.1Q VLAN tagging for flexible network segmentation.
Network engineers, storage architects, and IT procurement teams select the HPE 867707-B21 to consolidate high-speed connectivity in virtualized and bare-metal environments. Link aggregation via IEEE 802.3ad (LACP) enables redundancy and load balancing, while deep management integration through HPE iLO, HPE OneView, Intelligent Provisioning, and HPE SPP firmware updates ensures seamless deployment and lifecycle management. The adapter is certified for HPE ProLiant DL, ML, and BL Gen9/Gen10 servers as well as HPE Synergy platforms, and supports VMware ESXi, Microsoft Windows Server 2012 R2 and later, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server operating systems.
Organizations standardizing on HPE infrastructure can rely on this proven two-port 10GbE adapter to deliver reliable, manageable connectivity at scale. Contact Omnixon Global to request a quotation and explore volume pricing for the HPE 867707-B21 network adapter.
