615732-B21 HPE 332T 1G PCIe 2.0 x1 Ethernet Network Card

Low-Profile Dual-Port 1GbE PCIe Network Adapter for Virtualized Rack Servers with the 615732-B21

The 615732-B21 is an HPE 332T low-profile PCIe Ethernet NIC designed to add reliable dual-port copper networking to dense rack server configurations where 1GbE remains the operational standard. Based on the Broadcom BCM5720 controller, it targets virtualization hosts that need consistent VM connectivity, traffic segmentation, and predictable latency characteristics across shared infrastructure.

With a PCIe 2.0 x1 host interface, the 615732-B21 integrates cleanly into modern server platforms while preserving higher-bandwidth lanes for storage and accelerator expansion. Its dual RJ45 ports support 10/100/1000 connectivity for top-of-rack access and legacy switching environments, while offload and virtualization features such as VMQ, VMware NetQueue, and TSO help reduce CPU overhead under multi-VM network load. IEEE 1588 Precision Time Protocol support improves time synchronization for distributed workloads, and PXE boot enablement makes the adapter suitable for provisioning and management network roles alongside production traffic.

Why Choose the 615732-B21?

The 615732-B21 delivers a balanced density-to-performance profile for enterprise designs that prioritize port availability, deterministic 1GbE throughput, and operational continuity across mixed network generations. For standardized fleet deployments, the 615732-B21 supports scalable host builds by enabling consistent dual-port copper networking in a low-profile form factor, simplifying cabling and slot planning while maintaining enterprise reliability for always-on virtualization and management planes.

HPE engineers adapters such as the 615732-B21 to align with disciplined data centre lifecycle practices, including predictable firmware behavior, long-term platform compatibility, and integration expectations within HPE server ecosystems. This approach supports stable operation in consolidated racks where network interfaces are foundational to provisioning, monitoring, and workload mobility.

Key Applications:

• Virtualization host 1GbE VM connectivity
• Traffic segmentation for multi-tenant networks
• PXE provisioning and boot networks
• Legacy top-of-rack copper uplinks
