The HPE Ethernet 10/25Gb 2-port SFP28 BCM57414 Adapter (P08443-B21) is a dual-port enterprise network interface card powered by the Broadcom NetXtreme-E BCM57414 controller. Designed for ProLiant Gen10 and Gen11 servers running cloud virtualization, RoCE v2 storage traffic, and high-performance clustering, it supports 25GbE and 10GbE speeds with hardware offloads for VXLAN, NVGRE, and Geneve. It delivers sub-microsecond latency and RoCE v2 RDMA for NVMe over TCP and iSCSI storage networks. Used buyers should verify that genuine HPE firmware is loaded for complete iLO integration.

About the P08443-B21

P08443-B21 is HPE's dual-port 10/25GbE SFP28 PCIe adapter based on the Broadcom BCM57414 NetXtreme-E controller. Designed for enterprise virtualization, software-defined storage, and high-frequency cloud workloads on ProLiant Gen10 and Gen11 servers, it delivers line-rate RoCE v2 RDMA and packet processing offloads across a PCIe 3.0 x8 interface.

Compatibility

Fully certified across HPE ProLiant DL380 Gen10, DL380 Gen10 Plus, DL380 Gen11, DL360 Gen10, and DL360 Gen11 servers. Fits into any standard PCIe 3.0 or 4.0 x8 or x16 slot. Connects to HPE Aruba CX 8325 and CX 8360 switches, supporting iSCSI and NVMe/TCP storage traffic to HPE Alletra and MSA arrays.

How to identify a genuine unit

The card features a green PCB with two SFP28 cages and an aluminum heatsink over the Broadcom BCM57414 controller. HPE label indicates option part number P08443-B21, spare part number P09363-001, and assembly P08440-001. In iLO and OS tools, it displays under HPE vendor ID 103C.

Buying used

Inspect both SFP28 cages for bent contacts or damage to the grounding fingers. Verify that the card enters the server UEFI inventory and detects properly in HPE iLO. Confirm that both ports achieve 25GbE line rate, test with supported optical transceivers or DAC cables, and update cleanly using HPE SUM.

Works together

How the HPE P08443-B21 connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
