TCP/IP checksum offload, Large Send Offload (LSO), and Receive Side Scaling (RSS) capabilities deliver reduced CPU overhead and improved throughput for bandwidth-intensive enterprise workloads. The HPE Ethernet 1Gb 4-port 331T Adapter (part number 647594-B21) combines these performance-enhancing offload engines with a quad-port gigabit design built on the Broadcom BCM5719 controller, making it an ideal choice for network engineers upgrading HPE ProLiant server infrastructure.

This HPE network adapter features four RJ-45 ports rated at 1 Gbps (10/100/1000BASE-T), connected via a PCIe 2.0 x4 host interface in a low-profile form factor suitable for dense rack deployments. Each port supports standard Cat5e or Cat6 UTP copper cabling with a maximum distance of 100 m per port at 1000BASE-T speeds. The card is compatible with HPE ProLiant Gen8 and select Gen9 rack and tower servers, with full support for NIC teaming in both active-active and active-passive modes, IEEE 802.1Q VLAN tagging, and jumbo frames up to 9 KB. Power is delivered directly through the PCIe slot—no auxiliary connector required. Supported operating systems include Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi, with management integration through HPE Insight Control and HPE Intelligent Provisioning.

Deployment Scenarios

• Multi-NIC server aggregation and failover clustering in virtualized data centers
• Legacy ProLiant Gen8/Gen9 network interface upgrades for sustained 1 Gbps workloads
• VLAN-segmented production environments requiring low-latency packet processing and RSS load balancing
• Compliance-driven deployments where CE, FCC, and RoHS certification is mandatory
• Cost-effective four-port consolidation reducing physical switch port density
