About the HPE 629135-B21 - HPE 1Gb Ethernet 4-port 331FLR Adapter
The HPE 629135-B21 is a factory-original 1Gb Ethernet 4-port 331FLR Adapter designed for enterprise data center environments requiring reliable, low-latency network connectivity. This FlexibleLOM (FLR) interface adapter integrates directly into HPE ProLiant server slots, eliminating the need for external PCIe expansion cards and reducing physical footprint within dense server racks. Built around the proven Broadcom BCM5719 controller, the 629135-B21 delivers per-port throughput of 10/100/1000 Mbps across all four RJ-45 connectors, making it ideal for mission-critical applications spanning virtualization, storage networking, and enterprise workloads.
Network engineers and IT procurement teams deploying HPE ProLiant DL360p Gen8, DL380p Gen8, DL560 Gen8, DL580 Gen8, and select Gen9 FlexibleLOM-equipped servers will benefit from advanced offload capabilities—TCP, UDP, and IP checksum processing—that reduce CPU overhead and improve throughput efficiency. The adapter supports IEEE 802.3, 802.3u, 802.3ab standards, VLAN tagging via 802.1Q, and Link Aggregation Control Protocol (802.3ad) for redundancy and load balancing. Jumbo frames up to 9KB MTU, PXE and iSCSI boot support, and Wake-on-LAN functionality provide comprehensive network provisioning and management flexibility. Seamless integration with HPE iLO, HPE Intelligent Provisioning, HPE Smart Update Manager (SUM), and Service Pack for ProLiant (SPP) ensures straightforward deployment across VMware ESXi, Microsoft Windows Server, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server environments.
