HP HSTNS-BN80 (P/N 764285-B21) Dual-Port 544FLR-QSFP+ 10/40 GbE FlexibleLOM Adapter, Lot of 10: This is a lot of 10 refurbished dual-port FlexibleLOM (FLR) network adapters identified by HP assembly P/N HSTNS-BN80 and HP product number 764285-B21, commonly known as the HP 544FLR-QSFP. The card is built on Mellanox ConnectX-3 Pro silicon and is a server-side LAN-on-motherboard option for HP ProLiant Gen8 and Gen9 servers. This is NOT a standard PCIe slot adapter and is NOT a standalone NIC for generic motherboards. All 10 units are sold in refurbished, professionally tested working condition.
Engineering Context: The 544FLR-QSFP installs into the HP FlexibleLOM connector and is electrically a PCIe Gen3 x8 endpoint. Dual QSFP+ ports support 10 GbE and 40 GbE Ethernet. The Mellanox ConnectX-3 Pro silicon adds NVGRE and VXLAN stateless overlay offloads, RDMA over Converged Ethernet (RoCE), and SR-IOV for virtualization, on top of the standard ConnectX-3 transport offload feature set.
Deployment & Use Cases: Server-side adapter for HP ProLiant Gen8 and Gen9 systems requiring 10 or 40 GbE QSFP+ uplinks; virtualization hosts using RoCE and SR-IOV for low-latency east-west traffic; converged Ethernet fabrics with VXLAN or NVGRE overlay networks; high-throughput web, database, and analytics tier servers consolidating onto 40 GbE.

Compatibility & Constraints: Compatible with HP ProLiant Gen8 and Gen9 servers exposing the FlexibleLOM connector, HP-distributed firmware and drivers, QSFP+ DAC and AOC cables, and 10 GbE / 40 GbE switch ports. Will NOT install in standard PCIe slots (this is a FlexibleLOM-only form factor); NOT supported on ProLiant Gen6 / Gen7 generations; NOT a drop-in for HPE Gen10+ systems where the connector and form factor differ — verify HPE QuickSpecs for your exact server before deployment. The card is HP-firmware-locked; cross-flashing to non-HP Mellanox firmware is not supported by the OEM.
