HP 724206-B21 Ethernet 10Gb 1-Port 544+FLR-SFP+ Adapter: This is a single-port 10GbE network adapter in HP's FlexibleLOM Rack (FLR) form factor, designed for HP ProLiant Gen8 and Gen9 rack servers. The card uses a single SFP+ port and is built on NVIDIA Mellanox ConnectX-3 Pro silicon under HP firmware. This is an FLR mezzanine card, not a standard PCIe add-in card; it does not fit a generic PCIe slot. This is a new unit.
Engineering Context
The 724206-B21 delivers 10Gb/s Ethernet on a single SFP+ port with a PCIe 3.0 x8 host link. The HP FlexibleLOM connector is a dedicated mezzanine slot on supported ProLiant servers, freeing standard PCIe slots for other workloads. The card supports RDMA over Converged Ethernet (RoCE v1 and v2), SR-IOV with up to 127 virtual functions, and full TCP/UDP/IPv4/IPv6 stateless offloads. HP firmware adds Smart Component installer integration and HP iLO inventory reporting.
Deployment & Use Cases
10GbE expansion in HP ProLiant DL360, DL380, and DL580 Gen8 and Gen9 servers via the FlexibleLOM slot. Storage front-end connectivity to HP MSA, 3PAR, and Nimble arrays over iSCSI or NFS. RoCE-enabled SQL Server and Hyper-V Storage Spaces deployments on HP infrastructure. VMware vSphere virtual switch uplinks where the FLR slot is preferred for management or storage traffic.

Compatibility & Hard Constraints
Compatible with HP ProLiant Gen8 and Gen9 rack and tower servers that have a FlexibleLOM slot, including DL360 Gen8/Gen9, DL380 Gen8/Gen9, DL580 Gen8/Gen9, and ML350 Gen9. Drivers are integrated in the HP Service Pack for ProLiant (SPP) and ship with mainline Linux kernels and Windows Server. Not compatible with standard PCIe slots — this is an FLR-only mezzanine card. Not compatible with HP ProLiant Gen10 or Gen11 servers, which use OCP 3.0 NICs. The single SFP+ port is 10GbE only and does not support 25GbE SFP28.
