About the HPE 615732-B21 - HPE Ethernet 1Gb 2-port 332T Adapter
The HPE Ethernet 1Gb 2-port 332T Adapter delivers dual-port connectivity at 10/100/1000 Mbps with auto-negotiating support, making it an essential addition to enterprise server infrastructures requiring reliable Ethernet expansion. Built on the Intel 82576 network controller and backed by HPE engineering, the 615732-B21 combines proven performance with flexible deployment options across virtualized and physical environments.
This adapter connects via PCIe 2.0 x4 host interface in a low-profile form factor with full-height bracket included, fitting seamlessly into HPE ProLiant Gen7 and Gen8 server platforms. Network engineers and IT infrastructure teams rely on the 332T's comprehensive offload capabilities—TCP/IP checksum offload, UDP checksum offload, Large Send Offload (LSO), and Receive Side Scaling (RSS)—to reduce CPU overhead and maximize throughput. The adapter supports industry-standard IEEE protocols including 802.3, 802.3u, 802.3ab, 802.3ad, 802.1Q, and 802.1p, while VMDq and SR-IOV virtualization support enable efficient multi-tenant and virtual machine scaling. Jumbo frames up to 9 KB are supported for optimized data center workloads. Operating within a thermal envelope of just ≤5.5 W and rated for 0°C to 55°C operating conditions, the HPE 615732-B21 delivers enterprise-grade reliability with minimal power impact on system cooling and efficiency.
Whether you're modernizing legacy ProLiant infrastructure or expanding network capacity across a distributed environment, this dual-port gigabit adapter provides the connectivity density and advanced features your data center demands.
